Parts for the goods of subclass 43143

1. Scope and Applicability

This PCR covers discrete finished parts designed solely or principally for gas turbines other than turbo-jets and turbo-propellers. It applies to industrial, marine, vehicular, and power-generation gas-turbine parts supplied as accepted factory-gate goods, including cast, forged, machined, heat-treated, cleaned, and coated variants when those operations are performed by or for the reporting manufacturer.

Complete gas turbines, turbo-jets, turbo-propellers, their parts, repair or overhaul services, and general-purpose goods classified in their own right are outside scope. Examples of the latter include separately traded bearings, standard fasteners, valves, electrical controls, and generic transmission shafts. Transport packaging, installation, use, maintenance, remanufacture, and end-of-life are outside the reference flow. A dataset shall identify the exact part or part family, drawing or specification revision, material grade, manufacturing route, coating state, and acceptance state; category-average substitution without those qualifiers is not allowed.

The CPC reference establishes classification context only. The canonical PCR boundary is the engineering meaning above, which is independently useful for foreground data production.

Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	part name and function; drawing/specification revision; material grade and product state; cast/forged/additive or purchased-blank route; heat-treatment condition; coating type and state; net accepted mass; inspection and acceptance class; manufacturing site and geography; reference year; recycled-content claim where used; treatment and recovery destinations; excluded transport packaging

The exact reference-product UUID remains unresolved under inventory row output_finished_gas_turbine_part. When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

dq_identity	reference product and material inputs	Preserve part identifier, drawing revision, function, material grade, supplied state, heat treatment, coating, and acceptance class; do not aggregate unlike parts without a documented representative-product model.	controlled traveler, bill of materials, certificate of analysis, release record
dq_temporal	foreground records	Use one common representative period for inputs, outputs, emissions, and accepted mass; explain shutdowns, campaigns, abnormal production, and incomplete months.	period reconciliation and production calendar
dq_metering	energy, gas, water, and mass	Use calibrated meters or reconciled records; document meter boundary, unit conversion, reference conditions, estimation fraction, and allocation driver.	calibration certificates, invoices, meter map, calculation workbook
dq_completeness	process inventory	Account for every included process, purchased blank, major material, energy input, direct emission, chip stream, spent fluid, and spent bath; document zero and not-applicable conclusions.	signed process-flow review and completeness reconciliation
dq_mass_balance	metal and coating material	Investigate unexplained metal or coating-powder balance differences and retain corrections, rejected lots, rework, internal recycling, and inventory changes.	balance worksheet and corrective-action record
dq_representativeness	upstream datasets	Record geographical, technological, temporal, and product-state representativeness for each upstream dataset and disclose proxies.	dataset metadata and representativeness assessment

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validation_rule_1	reference_flow	Confirm the output is a discrete part for a non-turbo-jet/non-turbo-propeller gas turbine and that all required qualifiers and the 1 kg accepted net-mass basis are present.	un-cpc-3-0-structure-2025
validation_rule_2	process_coverage	Confirm every required process is represented and every conditional process has an evidence-backed included or not-applicable determination.	eu-jrc-sf-bref-2024; eu-jrc-stm-bref-2006
validation_rule_3	inventory_atomicity	Confirm every inventory row is one concrete exchange and that no row combines fuels, utilities, chemicals, wastes, packaging, or emission groups.
validation_rule_4	uuid_identity	Confirm each populated UUID is public state 100 and semantically matches flow name, flow type, classification, property, and unit; keep unresolved product-specific identities explicit.
validation_rule_5	evidence_traceability	Confirm each collected or calculated row links to an implemented collection protocol and that external source ids support only the stated method or boundary role.	eu-pef-recommendation-2021
validation_rule_6	energy_emissions	Reconcile natural-gas use with included direct fossil CO2 and nitrogen-oxides records, and confirm purchased-electricity upstream emissions are not duplicated as direct site emissions.
validation_rule_7	material_balance	Reconcile qualified metal stock, accepted output, segregated chips, rejects, transfers, and inventory changes; investigate every material unexplained difference.	us-epa-mpm-effluent-guidelines-2003
validation_rule_8	allocation_and_disclosure	Confirm shared-process allocation uses a documented causal physical driver and that subcontracting, recovery routes, credits, cut-offs, and transport-packaging exclusion are disclosed.	eu-pef-recommendation-2021

10. Published Dataset Profile

Field	Value
dataset_role	Factory-gate foreground production dataset for an identified finished gas-turbine part
downstream_use	secondary_dataset; background_dataset
allowed_use	Product-specific supply-chain modelling when the part identity, function, material grade, route, coating state, geography, time, acceptance criteria, allocation, and packaging exclusion are compatible
excluded_use	Complete gas turbines; turbo-jets or turbo-propellers and their parts; repair or overhaul; use-phase performance; unqualified category averages; comparative assertions across materially different part functions, alloys, routes, or coating states
required_metadata	PCR id and version; part and drawing identity; function; material grade and state; route and subcontracting; heat treatment; coating; net mass; site and geography; reference period; meters and allocation; upstream datasets; emissions; wastes and destinations; cut-offs; unresolved UUIDs
required_quality_disclosure	Primary-data coverage; estimated share; calibration and reconciliation results; metal-balance difference; representativeness of upstream datasets; allocation sensitivity; rejected lots and rework; uncertainty; unresolved range evidence and UUID gaps
update_trigger	Drawing, material grade, supplied blank state, manufacturing route, coating specification, inspection class, supplier, site, energy system, emission control, allocation driver, or foreground data changes that materially affect the inventory
