Electrical apparatus for switching or protecting electrical circuits, for making connexions to or in electrical circuits, for a voltage not exceeding 1000 V

1. Scope and Applicability

This PCR applies to factory-gate foreground data packages for discrete electrical apparatus whose principal function is switching, protecting, controlling by electromechanical switching, or making a connection to or within an electrical circuit, with a declared rated voltage not exceeding 1,000 V. Covered families include circuit-breakers and related protective devices; fuses, fuse-links, fuse-holders, and fuse-combination units; switches and disconnectors; relays and control-circuit switching devices; contactors and motor-starter switching devices; terminals, plugs, sockets, and electrical connectors. The declared product family and applicable product standard are mandatory scope facts.

This is a family-separated PCR, not a rule for an undifferentiated average of the entire category. A data package shall represent one declared product family and a homogeneous model group. It shall not extrapolate a household circuit-breaker, one industrial contactor, one fuse design, or one connector design to the whole category. Comparisons require the same product family, electrical function, rated-voltage basis, rated-current basis, duty or utilization category, protective or switching performance, pole or contact configuration, and reference-flow convention.

The default boundary is cradle-to-factory-gate production of tested finished apparatus. It includes received materials and purchased components, controlled component preparation, assembly, factory testing, direct utilities and process aids, production losses and wastes, and primary packaging when supplied with the product. Installation, switchboard or cabinet integration, use-phase losses and operations, maintenance, replacement, and end-of-life are outside the default boundary and require separate scenarios.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivision_first	shared production lines and utilities	First separate records by apparatus family, model group, production route, and test plan. Use physical submetering, work orders, machine time, test logs, and production quantities before applying allocation.	iec-ts-63058-2021
allocation_causal_then_mass	inseparable shared inputs and outputs	When subdivision is impracticable, use a documented causal driver such as machine time, test duration, or measured energy demand. Use net conforming product mass only when no defensible causal relation is available, and disclose the affected share and sensitivity.	iec-ts-63058-2021
allocation_rework_and_rejects	rework, rejects, and destructive testing	Return rework burdens to the model group that caused them. Assign non-reworkable rejects and destructive-test articles to the tested production lot; do not distribute one family's test burden across unrelated families.	iec-60947-1-2020
allocation_recycling_separate	manufacturing scrap and recovered materials	Report scrap mass, composition, and actual treatment route at the factory gate. Do not net scrap revenue, recycled-content claims, or avoided virgin-material credits from foreground inputs; any recycling credit requires a separately declared downstream method and sensitivity result.	iec-ts-63058-2021

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_count_to_net_mass	item-based production, test, and dispatch records	For each model, net mass = item count × measured model-specific net mass per item. Update the conversion after a BOM, enclosure, contact system, accessory set, or packaging-convention change.	item count; sampled net kg/item; model id; effective dates	kg net apparatus by model and period
calc_material_balance	materials and components	For each material or component class, net consumption = opening stock + receipts − returns − closing stock. Reconcile net consumption to incorporated product mass + measured scrap + rejects + documented stock or work-in-progress change.	stocks; receipts; returns; BOM issues; product mass; scrap; rejects; work in progress	kg input and reconciliation difference per kg conforming output	iec-62474-2018
calc_energy_intensity	preparation, assembly, and testing energy	Energy intensity = included metered energy ÷ net conforming tested apparatus mass for the same model group, site, and period. Allocate only residual shared energy with the declared causal driver.	meter readings; excluded loads; allocation driver; conforming output mass	kWh per kg net conforming apparatus
calc_test_yield	factory testing	Test yield = conforming released mass ÷ tested input mass. Report rework-return mass, non-reworkable rejects, and destructive samples separately so the ratio is auditable.	tested input; pass; rework; reject; destructive sample masses	dimensionless yield and kg dispositions per kg conforming output	iec-60947-1-2020
calc_direct_release	concentration-based direct releases	Release mass = sampled concentration × measured discharge or exhaust volume, with unit conversion and sampling-period coverage documented.	concentration; volume; sampling duration; conversion factor	kg substance per kg net conforming apparatus
