Complete EP multi-ply vulcanized rubber conveyor belts

1. Scope and Applicability

This method covers a real industrial subset: complete flat conveyor belting with multiple EP woven polyester-warp/polyamide-weft carcass plies, rubber skim between plies and SBR-based upper and lower rubber covers, laminated and sulfur-vulcanized, trimmed, inspected and supplied as open rolls. Actual ply count, EP finish, cover/skim formulations, edge form, dimensions, cure and acceptance specification are product-specific. Independent primary factory and commercial product evidence supports the structural/process synthesis; it does not establish one common SKU, formulation, cure condition, performance or lifetime. [fenner-belt-making-2023; fenner-superfort; somi-belt-process]

Exclude independently sold uncured cover/skim sheets, bare fabric carcasses, green builds, NN/EE or steelcord, proprietary single-ply designs, PVC/PU solid-woven belting, endless fabricated assemblies, profiled/sidewall belts and power-transmission belts. EP/NN/steelcord, recipes, grades, conditions, performance and service life are not interchangeable. Complete reinforcement/lamination/curing and supply distinguish this PCR from the external uncured SBR cover-sheet PCR; a changed application alone is not a new product methodology.

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	1 kg net supplied complete belt under cp_delivery; calibrated actual net mass excludes detachable packaging and preserves supplied moisture/retained material state. Native Mass does not establish density.
dimension_conversion	all inventory rows	Mass with measured dimensions	kg	Length/area/roll count converts to kg only with traceable paired net weighing for the same EP layup, width/gauges, compounds and roll configuration. Area uses actual length and width. No universal kg/m, kg/m2, roll weight or service transport amount; neither tensile data nor secondary property coefficients are density.
one_reporting_basis	all inventory rows	Physical quantity or energy declared by row	per 1 kg reference flow	Collect undivided raw period numerators with complete WIP/stock carried burdens. report_once is the only normalization after raw conversion and cohort attribution. Card A_i/Q and aggregation_rule denote that same operation, not successive divisions.
whole_preparation	all inventory rows	Whole supplied mass and constituent subledgers	kg	Bought compounds, oils, wet cements and dispersions count by whole supplied mass once. Active, carrier polymer/oil and water subledgers are not added procurement. Onsite blends use real separately acquired ingredients plus mixing energy/loss. Phr needs the actual recipe and measured base-rubber basis.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual purchased ingredients or whole uncured compounds, EP fabric and auxiliaries at plant receipt plus opening raw/WIP/finished/packaging stocks and carried burdens
starting_condition_role	Foreground receipt for complete-belt manufacturing/supply, not an upstream zero-burden cutoff
product_classification_scope	Narrow complete EP multi-ply conveyor-belt subset of CPC3.0 36240
recursive_input_rule	Pair internal compounds, coated fabric, green belt, trim and release/warehouse transfers with burdens, without repurchase. External same-category finished belts are not automatic primary-route inputs; independently verify state/route and upstream data, avoiding infinite recursion
upstream_dataset_requirement	Match each actual grade/form/recipe/route, geography, period and utility to compatible provider evidence. Bought complete compounds include upstream mixing; physical native identity alone is not quantitative provider evidence
disclosure	Plant/period, actual EP structure/recipe/cure, supply state, Q/P gate, WIP/finished carry, actual storage/pack/dispatch and all source/native limits

rule_id	applies_to	rule	source_ids
boundary_complete	belt_supply	Include real onsite mixing or upstream whole-compound supply, warm milling/calender/fabric coating, ply layup/lamination and green checks, sulfur press/end cooling, trim/test samples/real repair/final QC, winding/packing, actual warehousing and factory handling/dispatch. Retain failures, zero-output runs, rework, cleaning and opening/closing WIP burdens. No duplicated bought-compound and ingredient charges.	fenner-belt-making-2023; somi-belt-process; fenner-rubber-2024
boundary_delivery	product	Q is actual unique net factory delivery, not new release P. Keep finished opening/closing stock and exchange-level carried burdens; undelivered stock stays outside Q. Separate production and store/dispatch ledgers and cancel internal P handovers on consolidation, retaining all real storage, packaging, handling and rework. Return/reacceptance never creates new P or duplicate delivered Q.
boundary_downstream	belt_supply	Receipt does not remove upstream burdens. Customer freight, installation/endless splicing, conveying service, use and end of life require downstream models beyond this open-roll factory gate. Real factory dispatch/loading energy remains inside. No assumed transport-service output or life/equivalence across EP, NN and steelcord.	fenner-superfort; somi-belt-process

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
belt_supply	Complete EP multi-ply manufacturing and factory delivery	required	Actual §1 subset and route with independent stage records	Compound/mix → calender/fabric coat → ply lamination/green check → sulfur press/end cooling → trim/test/repair/QC → winding/packing/storage/dispatch; integrated unit	per 1 kg reference flow

Retain separate stage records for every actual compound, EP ply, cure batch and supplied cohort. Compounds, coated fabric and green builds are internal states: subprocess models pair/cancel transfers and retain carried burdens. Only product is terminal reference. Concrete conditional cards are actual-record triggers, not a universal recipe. Add separate specific cards for every additional real grade, preparation, treatment, fuel/refrigerant, packaging article, external coproduct or elementary species. A real outward intermediate or coproduct remains explicit, regardless of shared UUID.

Conveyor or transmission belts or belting, of vulcanized rubber (product)

Terminal complete sulfur-vulcanized flat belt: multiple EP polyester-warp/polyamide-weft plies, separate skim and SBR-based upper/lower covers, after trim, final QC, actual repair, winding/packing, warehousing and factory dispatch handling, supplied open-roll. Q is actual unique accepted net factory delivery, not newly released P, excluding detachable packaging. Native identity is Product flow; Production mix, at plant; Finished product, manufactured; Mass only. No fixed grade, polymer recipe, reinforcement, CAS or separate geography/locationOfSupply/medium is declared; unspecified geography is not a CN/HK/global representativeness claim.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_scope	belt_supply	Apply the declared attributional case and ILCD7.9.2/7.9.3 hierarchy. First subdivide or virtually subdivide dedicated batches, lines, tests, storage and supply burdens using actual meters/transfers. Distinct recipe/product cohorts are not interchangeable and no blanket plant-wide mass/revenue share is assumed.	ilcd-allocation-2010
allocation_physical	belt_supply	For each remaining shared exchange establish determining physical causality from actual engineering evidence. A measured process relation or storage area/volume and duration may support its specific driver; generic mass, machine time or rated power alone does not. Retain drivers, equations and completeness for all products.	ilcd-allocation-2010
allocation_remaining	belt_supply	Only for remaining shared burdens that the preceding steps cannot attribute, document why and use actual coproduct market values at the same process exit condition, period and quantity/quality. Preserve prices/currency and evidence-backed deductions for later packaging/transport if required. Allocated inventories must sum to preallocation inventory. No arbitrary physical/economic switch, fixed split or full ILCD/PEF compliance claim.	ilcd-allocation-2010
allocation_returns	belt_supply	Internal trim/dust, returns and rework are not new coproducts, negative procurement or automatic recycling credits. Actual sold off-grade belts/rubber or recovered articles need explicit separate Product/Waste outlets, receivers, boundaries and supported allocation/treatment. Never hide them by renaming or sharing the reference UUID without their physical roles.	ilcd-allocation-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.

8. Foreground Data Collection, Calculation, and Quality Rules

collection_method retains undivided raw period numerators and complete WIP/finished-stock carried burdens. aggregation_rule declares the final basis of the same single report_once operation, not normalization during collection.

Data Collection Protocols

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.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
report_once	all inventory rows	a_i = A_i / Q. A_i is each undivided atomic numerator uniquely attributed to the same actual supplied product/recipe/route/state cohort after raw conversions, dedicated/shared attribution and opening/closing raw-material, WIP and finished-stock burden adjustments. Q is positive unique accepted net factory-delivered belt kg from cp_delivery. Retain full-period failed/zero-output/rework burdens and opening carried burdens, carry closing undelivered burdens forward, then normalize once. Cards and aggregation_rule denote this same reporting operation. Reference output is Q/Q=1 kg.	A_i; Q; cp_delivery; cp_material; cp_structure; cp_utility; cp_pack; cp_outlet; cp_emission	a_i
raw_conversion	all inventory rows	Convert actual gross/tare/net mass to kg. Length/area/roll count requires paired net belt weighing and exact configuration in cp_delivery/cp_structure, never fixed kg/m or service amount. Material volume requires real same-state density. Rate times duration gives a numerator; integrated gas/liquid volumes get no extra time. Preserve gas conditions/heating value, steam mass/enthalpy and electrical/thermal units before report_once.	cp_delivery; cp_structure; cp_material; cp_utility; cp_pack; cp_outlet; cp_emission	converted raw numerators
physical_closure	belt_supply	Independently reconcile physical mass and elements for every control volume: opening stock plus actual external inflows equals closing stock plus all actual external outflows including each Product outlet, utility return, accompanying packaging, waste and elementary species. In production count new release P once; do not add the same cohort closing finished stock again as another production output. Separate finished-store accounting retains opening stock, internal P handover, Q, return/rework, closing stock and carried burdens. Cancel internal transfers on consolidation. Actual species, free/carrier/structural water and independently evidenced chemical water formation/consumption remain distinct. Never fit an unknown outlet and unknown reaction water to one closure residual or COD. Sulfur curing establishes no generic net water yield.	cp_delivery; cp_material; cp_structure; cp_utility; cp_pack; cp_outlet; cp_emission	raw physical mass element and burden ledgers
whole_inputs	belt_supply	Whole externally supplied compounds, oils, wet cements and dispersions count as single purchased preparations. Assayed active/polymer/carrier/water fractions reconcile within that mass, without duplicate procurement. Onsite mixing uses actual separately bought ingredients and real energy/losses. Packaging and reusable reel/cloth ledgers retain acquisition, opening/closing stock, accompanying outputs, returns/discard/reuse independent of belt Q.	cp_material; cp_pack; cp_delivery	nonduplicated preparations and packaging
asset_manufacture_share	existing capital/reusable manufacture attribution	For each included original asset manufacture vector B, f_current = u_current / D only after the persistent ledger verifies the supported whole installed-service denominator, all beneficiaries and prior assigned shares. Attribute f_current * B once to the actual beneficiary before the existing single reference normalization. Check prior_shares + all current/new beneficiary shares <= 1; carry the remaining original balance. Capacity revisions reconcile the historical ledger. Full physical asset/packaging mass and actual gross stocks/returns never receive f_current. Unknown D or history leaves the final attributed result unavailable, without suppressing actual repair/replacement/service burdens.	asset_id; original_B; u_current; D; historical_beneficiaries; prior_shares; capacity_evidence	conserved attributed manufacture vector

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_identity	belt_supply	Verify real multiple EP woven layers, distinct skim, SBR-based two covers and complete sulfur-vulcanized open-roll acceptance. Native broad names prove no EP/NN/steelcord, grade or life equivalence.	fabric/compound supplier records; complete layer BOM; cure/final acceptance
quality_period	all inventory rows	Complete period inputs/burdens include failures, zero-output batches, rework, WIP and finished-stock carry; Q is actual positive unique net delivery, never P, gross throughput or packed mass.	period/cohort and physical stock reconciliation; return links; exchange-level prior burdens
quality_units	all inventory rows	Calibrated mass/energy, same-configuration length/area/count conversion, whole preparations and independent physical/species evidence; no default weight, recipe, yield, service quantity, cure condition or reaction water.	calibration; assays; paired net weighing; condition/phase and species evidence
quality_projection	belt_supply	Preserve every native name component, comment debt, grade/form/route/geography/medium and exact property/unit restriction in consumable context. Both projections retain every raw table/source/protocol/calculation/quality field and full limitations. Schema/ID equality alone is insufficient.	complete direct original; primary sources; raw-to-typed audit; provider evidence

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	product	reference_flow_link selects one actual terminal Product output with the declared reference UUID: the independently qualified complete cured EP belt, never compound, green build, fabric or conveying service. Retain exact official Chinese basename and all native limits. Real other outputs retain their physical roles even if sharing UUID.
validate_delivery	all inventory rows	Verify positive unique net-delivery Q distinct from P, matched product/recipe/route/state/period and measured mass conversion. Reconcile full-period failures/rework, WIP/finished opening/closing masses and burdens, linked returns/reacceptance/redelivery and real storage/packing/handling/dispatch. report_once is the only normalization.
validate_balance	belt_supply	Check physical_closure and whole_inputs for every actual material/utility/packaging and Product/Waste/elementary outlet. Pair/cancel internal transfers, avoid double purchases and preserve independent water/species evidence without residual fitting. Complete all actual recipe/cure/utility/outlet rows before use.
validate_method	belt_supply	Enforce bounded EP structure and supply, collection owners, source/native/provider applicability, bilingual full-field retention and declared allocation hierarchy. Core reference/method contradictions block usable guidance; disclose ordinary future measurement/auxiliary UUID gaps without fabricating values. Scientific review is separate.	fenner-belt-making-2023; somi-belt-process; ilcd-allocation-2010
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.
