Armoured or reinforced safes, strong-boxes and doors and safe deposit lockers for strong-rooms, cash or deed boxes and the like, of base metal

1. Scope and Applicability

This PCR applies to factory-gate production of finished base-metal armoured or reinforced safes, strong-boxes, strong-room doors, safe-deposit lockers, cash boxes, deed boxes, and functionally similar secure-storage products within CPC 3.0 code 42993. It covers product configurations whose protective body or door is fabricated from base metal and reinforced by a security-barrier construction.

The PCR does not cover ordinary non-reinforced cabinets, furniture, locks supplied as stand-alone products, alarm systems, vault construction performed at the customer site, or upstream production of steel, coatings, barrier constituents, electronics, packaging, and purchased components. A data package shall identify whether it represents a complete safe, strong-box, strong-room door, locker bank, or smaller cash or deed box; products with materially different constructions or declared protection grades shall not be averaged without a documented representativeness justification.

al_avoid	all shared processes	Avoid allocation through process subdivision, dedicated meters, batch records, and direct assignment to the declared product family wherever practicable.
al_mass_balance	steel, barrier compound, coating, water, and packaging	Reconcile inputs, accepted product, internal returns, stock change, and measured waste before allocation; internal recycling shall not be counted as both a fresh input reduction and a credited output.
al_shared_energy	shared electricity	Allocate only the residual shared amount using a causal physical driver such as measured machine operating time multiplied by rated or measured load; document the driver and sensitivity.
al_multi_product	unavoidable multi-product production	If subdivision and causal assignment are infeasible, use mass allocation only when mass demonstrably represents resource use; otherwise select and justify another physical relationship and report an unallocated sensitivity case.	epd-international-godrej-high-security-safes-2025
al_scrap	recyclable steel scrap and other wastes	Report the waste at the factory boundary and connect the chosen downstream treatment dataset; do not apply an avoided-production credit inside the foreground unless required by the declared study method and shown separately.	epd-international-godrej-high-security-safes-2025

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids

calc_welding_particulate	welding_particulate	released particulate = measured exhaust mass, or consumable/activity amount × matched particulate factor × (1 − verified capture fraction); do not use a factor for a different welding process or electrode	source test or activity; matched factor; control performance	kg particulate per 1000 kg finished product	us-epa-ap42-electric-arc-welding-1995
