Electrical insulators, except of glass or ceramics; insulating fittings for electrical machines or equipment, except of ceramics or plastics; electrical conduit tubing and joints therefor, of base metal lined with insulating material

1. Scope and Applicability

This PCR applies to cradle-to-gate foreground data packages for three explicitly declared product families: electrical insulators made from materials other than glass or ceramics; insulating fittings for electrical machines or equipment made from materials other than ceramics or plastics; and electrical conduit tubing or conduit joints made from base metal and lined with electrically insulating material. The data producer shall select one product family and describe the finished product, material system, production route, and applicable performance specification.

The PCR covers receipt and preparation of materials, formation or application of the insulating body or liner, foreground fabrication and surface treatment of metal components when performed at the reporting site, assembly, curing, testing, marking, and market-ready packaging. It excludes glass insulators, ceramic insulators and ceramic insulating fittings, plastic insulating fittings, unlined metal conduit, conduit wholly made of insulating material, insulated wire and cable, installation, use, maintenance, and end-of-life. Upstream production of purchased materials and energy is represented by linked upstream datasets rather than recreated inside the foreground process.

The product families share an electrical-isolation purpose but are not interchangeable in service. A mass reference flow supports manufacturing inventory accounting; comparative claims additionally require the same product family, electrical rating, mechanical duty, dimensions, service environment, applicable standard, and declared service life.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	Reference product	Product family, material system, ratings, geometry, standard, and finished state shall match the declared semantic boundary and be traceable to accepted output records.	Product specification, bill of material, drawings, and acceptance record
dq_temporal_alignment	All foreground rows	Inputs, outputs, wastes, emissions, and accepted product mass shall cover the same representative period; exceptions and shutdown/start-up treatment shall be disclosed.	Meter dates, batch dates, waste tickets, and production ledger
dq_completeness	Process map and conditional rows	Reconcile all measured foreground input mass and metered foreground energy to the applicable process records, and identify and explain every excluded or unassigned flow individually; do not apply an undocumented environmental significance cut-off.	Material and energy reconciliation worksheets
dq_measurement	Meters, scales, and laboratory results	Record instrument identity, calibration status, detection limit where relevant, reference conditions for gases, and wet/dry or active-content basis for chemicals.	Calibration certificates, laboratory reports, and supplier certificates
dq_upstream_representativeness	Linked upstream datasets	Document geography, technology, time period, product state, and any proxy use for each upstream dataset; an unresolved proxy shall be flagged in the produced data package.	Dataset metadata and supplier information
dq_route_transparency	Conditional product-family processes	Mark every conditional row applicable or not applicable and give the physical reason; zero shall not be used when the value is merely unknown.	Route checklist, process flow diagram, and bill of material

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_identity	Reference flow	Fail validation if product family, material exclusions, mass basis, market state, or any required qualifier is missing, or if a proxy UUID is used for the unresolved reference product.	un-cpc-3-0-2025
validate_process_coverage	Process map	Require both mandatory processes and require the conditional metal process when foreground records show metal cutting, forming, cleaning, coating, or joint fabrication.	line-power-polymer-insulator-manufacturing; elot-ts-1501-04-20-01-01-2023
validate_atomic_flows	Inventory rows	Require one physical, chemical, waste, or elementary exchange per row, exact direction and flow type, an applicable/not-applicable decision, and an unresolved record whenever no exact UUID is confirmed.
validate_mass_energy_reconciliation	Foreground inventory	Require accepted-output normalization, route material-balance residual disclosure, utility reconciliation, and investigation of unexplained duplicated or missing flows.	mass-balance-identity
validate_direct_emissions	NMVOC, fossil CO2, and fine particles	Require the exact compartment/size fraction, monitoring or mass-balance method, abatement basis, and exclusion of upstream electricity and fuel-supply emissions from direct rows.
validate_bilingual_identity	UUID-bearing Chinese display names	Require the exact state-100 TianGong Chinese baseName and the same UUID, property, unit group, and row id as the English inventory.
