1. Scope and Applicability

This attributional PCR selects one product boundary: an uncoated nonphotochromic single-vision silicate spectacle-glass pressing blank of the standard crown family whose surfaces remain optically unworked. Cover the complete whole-raw-material-to-first-quality-release route using electric melting/fining/conditioning, gob shearing, hydraulic pressing, cooling and electric annealing. Record each actual supplied recipe component individually; no universal recipe, yield, density, energy, emission, temperature or lifetime defaults apply.

Exclude clock/watch cover glasses, spheres/segments, finished optical lenses, precision reheat moulding, fused segments, silver-halide photochromic activation, coating, chemical/thermal strengthening, ordinary cold-ground sheets and eyewear assembly. Adjacent specification categories, gobs and segments are counterexamples, not one combined method. Technical route synthesis does not establish one SKU or factory; an actual data package must prove its declared route.

2. Product Category Identity

excluded_products	Watch covers; glass spheres; segments; specialised photochromic/high-index routes; finished lenses; ordinary cold-ground sheets
representative_product	One drawing-defined annealed single-vision bare ophthalmic blank
production_route	Whole batch supplies → electric melt/fine/condition → gob shear → hydraulic press/cool → electric anneal/cool → first-release inspection
market_state	Optically unworked mineral glass blank supplied for later lens surfacing

3. Reference Flow

Field	Value
What	Unworked pressing stock for subsequent single-vision spectacle-lens manufacture
How much	1 kg net dry bare blank at first quality release
How well	Accepted against actual drawing and material/stress/dimension/defect methods; no finished-lens performance warranty
How long or cycle	One unique first quality release; later services retain their actual original-cohort observation window
reference_flow_link	finished_blank

Field	Value
Reference amount	1
Reference product flow	Clock or watch glasses and similar glasses, glasses for spectacles, not optically worked, hollow glass spheres and their segments for the manufacture of such glasses `86f99422-b0c1-4f90-8150-aa288e54a03f`
Reference flow property	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`
Reference unit group	Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66`
Reference unit	kg
Required qualifiers	single-vision blank drawing and dimensional configuration; silicate formulation and each whole supplied raw material; nonphotochromic and optically unworked surface state; electric melting/fining/conditioning and electric annealing route; press/shear/mould and actual lubrication state; material quality and residual-stress acceptance method; unique first-release cohort and net dry bare-glass kg Q; measured item-mass conversion configuration if count is used; opening/closing raw WIP FG and installed-fluid vectors; source-specific native identity restrictions and provider boundary; actual water phase/species evidence and physical closure; packaging construction and full stock/return routes; original-cohort services and explicitly observed horizon

All required qualifiers belong in dataset metadata, descriptions, reference comments or equivalent fields. Reference-product and later physical movements using this identity retain these restrictions: Only the not-optically-worked spectacle-glass member of this broad manufactured Product family is selected: one uncoated nonphotochromic single-vision silicate blank after pressing and annealing. Other members in its official basename do not enter this exchange. Native mix is at plant; no CAS, recipe, grade, optical finish, geometry, geography or provider is specified. The Chinese comment refers to making such articles; neither it nor the generic finished-product route proves a polished lens. Actual unworked state and drawing/QC must be documented.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Q is unique first-released dry bare-blank kg; closingFG is already in Q. Count-to-kg requires measured M for the same configuration or whole-lot weighing, never guessed item mass.
energy_unit	electricity; service_electricity	Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66`	MJ	Convert metered kWh to MJ by3.6 before attribution and the single normalization; electricity has no carrier mass.
mass_unit	silica; soda; potash; limestone; boric; alumina; antimony; ceria; nitrate; sulfate; cullet_in; mains_water; diwater; release_agent; hydraulic_oil; machine_oil; platinum_contact; refractory; mould; shear; filter; melter_asset; press_asset; lehr_asset; air_n2; air_o2; air_ar; air_h2o; air_co2; cullet_out; glass_waste; batch_dust; washwater; cool_purge; filter_waste; refractory_waste; mould_waste; shear_waste; platinum_return; exchange_return; co2_process; no_air; no2_air; so2_air; water_air; n2_air; o2_air; ar_air; co2_pass; silica_dust_air; boric_air; b2o3_air; fg_received; fg_dispatch; service_glass_waste; tray_purchase; tray_returned_in; tray_gross_out; tray_return_out; tray_waste; carton_purchase; carton_returned_in; carton_gross_out; carton_return_out; carton_waste; waste_hydraulic_oil; waste_machine_oil; exchange_water_in	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Whole materials and actual individual species use kg with independently measured moisture/phase/density; diagnostic totals do not substitute species. Do not apply this rule to MJ or tkm.
transport_unit	freight	Transport mass-distance	tkm	Use actual cargo tonnes and distance km; a mass-referenced truck/transport flow is incompatible.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Receipt of each actual whole mineral/chemical supply and compatible cullet with upstream supply/transport
starting_condition_role	foreground_gate
product_classification_scope	Only the unworked single-vision spectacle-glass pressing subset of CPC3.0:37194
recursive_input_rule	Same-category bought/returned supplies keep supplier/original-cohort burdens; internal cullet/transfers pair and cancel each vector
upstream_dataset_requirement	Upstream supply datasets matching actual form/native restrictions/provider boundary; no whole-provider plus constituent duplication
disclosure	Route/drawing/grade/supplier, all modes and stock history, species/water evidence, packaging and observed horizon

rule_id	applies_to	rule	source_ids
boundary_full	all processes	Start at receipt of each actual whole mineral/chemical supply and compatible cullet with upstream supply burdens and actual inbound logistics; include weighing/mixing, electric melt/fining, platinum-contact stirring/conditioning, gob shearing, hydraulic pressing/cooling, electric annealing/cooling, inspection and unique first quality release. Retain actual water/air utilities, abatement, maintenance, all nonproductive conditions, stocks and separate post-release services. Do not replace this manufacture with bought-blank packing.	`jrc-glass-bref-2013`; `corning-ophthalmic-manufacturing`; `corning-ophthalmic-spec-f-2013`
boundary_state	all processes	Apply only to the declared uncoated nonphotochromic single-vision silicate pressing blank. Do not require one modern order to prove the general unit operations; technical synthesis is not a same-factory recipe. Actual fuel-fired, reheat-pressed, photochromic-activation, fused-segment, optical-polishing/coating or tempered-lens routes need separate applicability review. If actual ancillary fuel or steam exists, disclose and add each atomic real supply, carrier mass/heat and return, rather than asserting zero or omitting it.	`jrc-glass-bref-2013`; `corning-ophthalmic-manufacturing`
boundary_history	manufacture	For every extensive exchange i retain its independent unnormalised inherited burden vector. A_i = B_open_i + C_i - B_close_i after actual unit conversion and attribution; manufacturing B_close includes raw stock, WIP and genuinely unassigned non-WIP stores, never this cohort closingFG already released into Q. Include failed batches, zero-output periods, start/stop, idle, cleanup, rejects and actual rework. No unmeasured history is set to zero. Distinguish gross receipts from a proved already-stock-adjusted material-consumption or issue basis. Correct the same raw-stock change once only; never apply opening/closing raw stock again to already measured consumption. Keep each disjoint raw/WIP and included non-WIP installed/store physical quantity and every inherited exchange vector separately. An explicit purchase/receipt, return, gross dispatch or waste-movement card retains its full converted physical leg; allocation/stock correction affects the separate burden or consumption vector, never that gross movement.	`jrc-ilcd-attributional-2010`
boundary_physical	all processes	Close manufacturing, FG/service and combined physical gates independently of burden allocation. For each whole material and each relevant element: opening physical stocks + gross actual external inputs = closing stocks + gross actual external outputs; internal transfers cancel exactly. Keep installed assets/fluids separately with new/repair/retirement events and wear. Do not shrink gross receipts, returns, shipments, wastes or packaging by economic allocation shares.	`jrc-glass-bref-2013`; `jrc-ilcd-attributional-2010`
boundary_species	all processes	Whole mass and elemental balances do not prove molecular speciation or reaction-water pathways. Independently determine moisture, free/structural/chemically generated water, evaporation and actual phase. For any unresolved two-unknown water/species system obtain a second independent observation; one closure residual cannot determine both. Separate gross air species, no aggregate air plus children; no conversion of COD/VOC/NOx/total-B/total-C or size bins into invented molecular species.	`jrc-glass-bref-2013`
boundary_expand	all inventory rows	This is a finite initial atomic inventory, not an assertion that every site contains only these materials. Compare each actual supply, asset/repair event, maintenance formulation, air/water outlet and packaging against it; add every real missing individual exchange, its native extensive property, protocol and uncertainty before modelling. Unknown actual core product/route/gate or unclosed required physical/species history prevents usable results. An auxiliary UUID/provider gap alone does not change product identity.	`jrc-glass-bref-2013`

Aqueous graphite mould-release suspension (`release_agent`)

Conditional whole supplied graphite-based release formulation. Record carrier water, binder and graphite assays only as subledger. If mixed on site, replace the bought formulation with every actual separately purchased constituent and mixing energy/loss.

Outputs

Product flows

First-released unworked ophthalmic blank (`finished_blank`)

This unique Product output links the reference object. Q is new unique first-quality-released net dry bare-blank mass after pressing, annealing/cooling and documented drawing/material/stress acceptance; no lens surfacing, polish, coatings, fusion segments or packaging. ClosingFG of this cohort is already in Q and is not another production output. Only the not-optically-worked spectacle-glass member of this broad manufactured Product family is selected: one uncoated nonphotochromic single-vision silicate blank after pressing and annealing. Other members in its official basename do not enter this exchange. Native mix is at plant; no CAS, recipe, grade, optical finish, geometry, geography or provider is specified. The Chinese comment refers to making such articles; neither it nor the generic finished-product route proves a polished lens. Actual unworked state and drawing/QC must be documented.

Nitrogen monoxide to air (`no_air`)

Only an actually identified species and phase crossing to the actual compartment is quantified. Include all measured failed/start-stop/idle/cleanup conditions. A total elemental result, NOx/SOx, VOC, COD or total particulate result is a diagnostic subledger, not evidence for this molecular amount. Retain real unmeasured species as unresolved, not zero. NO CAS10102-43-9 Elementary air-unspecified emission only. Native synonym noise includes HNO but the adopted species is molecular NO; actual species-resolved measurements required. NOx-as-NO2 is not this mass. Native reference property → unit group → reference unit: 93a60a56-a3c8-11da-a746-0800200b9a66 → 93a60a57-a4c8-11da-a746-0800200c9a66 → kg. Quantity linkage: this row x_i is the single calc_reference result from undivided raw cp_emissions after calc_raw_conversion, calc_history and actual attribution; cards and aggregation never divide again.

A total elemental result, NOx/SOx, VOC, COD or total particulate result is a diagnostic subledger, not evidence for this molecular amount. Retain real unmeasured species as unresolved, not zero. NO2 CAS10102-44-0 Elementary emission to air unspecified; synonyms mention N2O4, which cannot establish its mass. Require phase/species-specific evidence and equilibrium treatment where relevant, never total NOx allocation by assumption.

Only an actually identified species and phase crossing to the actual compartment is quantified. Include all measured failed/start-stop/idle/cleanup conditions. A total elemental result, NOx/SOx, VOC, COD or total particulate result is a diagnostic subledger, not evidence for this molecular amount. Retain real unmeasured species as unresolved, not zero. SO2 CAS7446-09-5 Elementary air-unspecified emission only, not total SOx or sulfate dust. Confirm native CAS, actual molecular speciation and location; no default sulfate conversion fraction.

Only an actually identified species and phase crossing to the actual compartment is quantified. Include all measured failed/start-stop/idle/cleanup conditions. A total elemental result, NOx/SOx, VOC, COD or total particulate result is a diagnostic subledger, not evidence for this molecular amount. Retain real unmeasured species as unresolved, not zero. H2O CAS7732-18-5 Elementary water-vapour emission to air unspecified; noisy heavy/tritiated-water synonyms are excluded. Keep evaporation, inlet humidity, actual chemical reaction water and retained structural water distinct; liquid droplets require a separate physical phase.

System boundary rules · 6

Rule ID	Applies to	Rule	Source IDs
`boundary_full`	all processes	Start at receipt of each actual whole mineral/chemical supply and compatible cullet with upstream supply burdens and actual inbound logistics; include weighing/mixing, electric melt/fining, platinum-contact stirring/conditioning, gob shearing, hydraulic pressing/cooling, electric annealing/cooling, inspection and unique first quality release. Retain actual water/air utilities, abatement, maintenance, all nonproductive conditions, stocks and separate post-release services. Do not replace this manufacture with bought-blank packing.	jrc-glass-bref-2013, corning-ophthalmic-manufacturing, corning-ophthalmic-spec-f-2013
`boundary_state`	all processes	Apply only to the declared uncoated nonphotochromic single-vision silicate pressing blank. Do not require one modern order to prove the general unit operations; technical synthesis is not a same-factory recipe. Actual fuel-fired, reheat-pressed, photochromic-activation, fused-segment, optical-polishing/coating or tempered-lens routes need separate applicability review. If actual ancillary fuel or steam exists, disclose and add each atomic real supply, carrier mass/heat and return, rather than asserting zero or omitting it.	jrc-glass-bref-2013, corning-ophthalmic-manufacturing
`boundary_history`	manufacture	For every extensive exchange i retain its independent unnormalised inherited burden vector. A_i = B_open_i + C_i - B_close_i after actual unit conversion and attribution; manufacturing B_close includes raw stock, WIP and genuinely unassigned non-WIP stores, never this cohort closingFG already released into Q. Include failed batches, zero-output periods, start/stop, idle, cleanup, rejects and actual rework. No unmeasured history is set to zero. Distinguish gross receipts from a proved already-stock-adjusted material-consumption or issue basis. Correct the same raw-stock change once only; never apply opening/closing raw stock again to already measured consumption. Keep each disjoint raw/WIP and included non-WIP installed/store physical quantity and every inherited exchange vector separately. An explicit purchase/receipt, return, gross dispatch or waste-movement card retains its full converted physical leg; allocation/stock correction affects the separate burden or consumption vector, never that gross movement.	jrc-ilcd-attributional-2010
`boundary_physical`	all processes	Close manufacturing, FG/service and combined physical gates independently of burden allocation. For each whole material and each relevant element: opening physical stocks + gross actual external inputs = closing stocks + gross actual external outputs; internal transfers cancel exactly. Keep installed assets/fluids separately with new/repair/retirement events and wear. Do not shrink gross receipts, returns, shipments, wastes or packaging by economic allocation shares.	jrc-glass-bref-2013, jrc-ilcd-attributional-2010
`boundary_species`	all processes	Whole mass and elemental balances do not prove molecular speciation or reaction-water pathways. Independently determine moisture, free/structural/chemically generated water, evaporation and actual phase. For any unresolved two-unknown water/species system obtain a second independent observation; one closure residual cannot determine both. Separate gross air species, no aggregate air plus children; no conversion of COD/VOC/NOx/total-B/total-C or size bins into invented molecular species.	jrc-glass-bref-2013
`boundary_expand`	all inventory rows	This is a finite initial atomic inventory, not an assertion that every site contains only these materials. Compare each actual supply, asset/repair event, maintenance formulation, air/water outlet and packaging against it; add every real missing individual exchange, its native extensive property, protocol and uncertainty before modelling. Unknown actual core product/route/gate or unclosed required physical/species history prevents usable results. An auxiliary UUID/provider gap alone does not change product identity.	jrc-glass-bref-2013

Allocation rules · 6

Rule ID	Applies to	Rule	Source IDs
`allocation_rule_1`	foreground_burden_allocation	These attributional rules apply only to uncoated nonphotochromic single-vision optically unworked silicate ophthalmic pressings, from whole supplied batch materials through electric melting/fining/conditioning, gob shearing, hydraulic pressing/cooling and electric annealing to unique first quality release, plus actual original-cohort services. Exclude watch covers, spheres, fused segments, photochromic activation, finished optical surfacing/polishing/coating and other heating/forming routes. Consume every rule with this scope and its ancestor conditions.
`allocation_scope`	all processes	Use only the declared attributional inventory context where allocation is appropriate after goal/scope choice. Assign dedicated measurements and use physical/virtual subdivision first; keep exclusively related raw materials, rejection/rework and services with their actual product/cohort. Industrial manufacturing documents are not allocation evidence.	jrc-ilcd-attributional-2010
`allocation_causal`	shared process exchanges	For each genuinely shared exchange determine which physical relationship controls that exchange quantity. Use measured heat capacity/enthalpy and thermal history for heating only where causal; processing time/load or another extensive driver must be justified per exchange. A mass share is not automatically valid for all electricity, cooling, assets or pollutants. Retain method, measurements, uncertainty and sum conservation.	jrc-ilcd-attributional-2010
`allocation_residual`	remaining shared exchanges	Only a demonstrably remaining common-process burden without a determining physical relationship may use economic allocation: actual quantities and contemporaneous market values of cofunctions in their actual condition at the same process exit/entry gate. Explain the residual, period, quality, packing state, currency and volatility. Never freely choose physical versus economic shares, fixed ratios, avoided-production credits, or automatic cullet/recovery benefits.	jrc-ilcd-attributional-2010
`allocation_service`	services	Post-release handling/packaging/storage and actual returns retain original cohort Q and each original inherited burden vector; record only actual incremental service/rework/loss burden in its observed horizon. Do not remove manufacturing burdens of closingFG from original first-release Q, add closingFG as another production output, or create Q by reinspection or dispatch. An independently reported net-delivery study needs gross G/R, original-delivery reversal D_rev, opening/closingFG history and measured new water/loss/rework; this first-release denominator cannot be silently reused.	jrc-ilcd-attributional-2010
`asset_manufacture_conservation`	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Validation rules · 7

Rule ID	Applies to	Rule	Source IDs
`validation_rule_1`	foreground_dataset_conformance	These checks concern only uncoated nonphotochromic single-vision optically unworked silicate ophthalmic pressings, complete whole-batch electric melting/fining/conditioning, gob shearing, hydraulic pressing/cooling, electric annealing, first quality release and observed original-cohort services. Watch covers, spheres, fused segments, photochromic activation and optically finished lenses are excluded. This is never whole37194 coverage; engineering checks do not replace scientific, translation or mapping decisions.
`validate_terminal`	reference product	Verify drawing, silicate family, nonphotochromic single-vision state, unworked surfaces, pressing/annealing route and real quality gate; finished lenses, glass spheres/watch covers and generic optics are not substitute endpoints. Missing primary core route/terminal or unresolved true core native identity keeps the draft unusable regardless of engineering checks.	corning-ophthalmic-spec-f-2013, corning-ophthalmic-manufacturing
`validate_quantities`	all inventory rows	Verify consistent first-release Q and units in both languages, exactly one calc_reference A_i/Q and complete raw conversion/history attribution. All failures, zero output, start-stop, idle, cleanup, rework and stock vectors must remain. Unsupported/unknown relationships are unresolved, not pass; report Q0 without unit inventory.	jrc-ilcd-attributional-2010
`validate_identity`	all inventory rows	For adopted UUIDs inspect every native basename, synonyms/comments, CAS, route/form/grade, geography/medium/type and all properties, including the exact reference-property/unit-group chain. Use official Chinese basename. Provider selection still needs actual fit; no support record or classifier alone proves applicability. Leave concrete unbound atoms explicit and do not replace them with a collection label.	jrc-glass-bref-2013
`validate_closure`	all processes	Require independent whole-mass/element and actual molecular/phase/water evidence at consistent manufacturing, FG and combined gates. Reconcile each packaging/asset/fluid stock and all gross directions independently of economic shares. Quantified diagnostic totals cannot create unmeasured species; unknown outlet/state or missing inherited history blocks a concrete usable inventory.	jrc-glass-bref-2013, jrc-ilcd-attributional-2010
`validate_evidence`	all processes	Disclose the complete manufacturer page as publisher-origin web-tool-rendered text, not locally acquired publisher HTML/PDF. Read its raw-batch, forming, standard-annealing, photochromic countercontext and packing sections together with the complete 2013 Corning specification and Glass BREF. They support a bounded qualitative synthesis, not one contemporary all-electric plant order, recipe or numerical default. Failed local acquisition alone is not a core-content gap. Scientific judgement, aligned translation review, mapping acceptance and publication remain separate decisions.	corning-ophthalmic-spec-f-2013, corning-ophthalmic-manufacturing, jrc-glass-bref-2013
`validate_asset_manufacture_conservation`	existing capital/reusable manufacture attribution	For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.
