1. Scope and Applicability
This PCR applies to factory-gate production of finished parts intended exclusively or principally for furnace burners, mechanical stokers, mechanical grates, mechanical ash dischargers, industrial or laboratory furnaces and ovens, industrial induction or dielectric heating equipment, and non-electric bakery ovens. It covers an individually declared part or homogeneous part family made through one reported bill of materials and manufacturing route.
The foreground begins when purchased metals, castings, refractory ceramic components, process consumables, energy, and water enter the manufacturing site. It ends when the conforming part has passed final inspection and is ready to leave the factory gate. Complete burners, stokers, grates, ash dischargers, furnaces, ovens, bakery ovens, generic fasteners and bearings not identifiable as parts of the covered equipment, installation, use, maintenance, and end-of-life are outside this PCR.
Because the product category contains materially different parts and routes, the dataset shall declare the part identifier, host equipment, bill of materials, material grades, fabrication stages, surface condition, and included packaging. Each additional actual bill-of-materials item or generated waste not represented below shall be added to the foreground inventory as its own atomic exchange.

allocation_economic_fallback | Shared processes lacking a defensible physical relationship | Use economic allocation only as a documented fallback, disclose prices, period, currency, and sensitivity, and do not use it to hide missing production records. | ec-pef-method-2021 |

System boundary rules · 4
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
boundary_factory_gate | Foreground system | Include all on-site operations from receiving the declared purchased inputs through final inspection and factory-gate readiness of the accepted part. | ec-pef-method-2021 |
boundary_route_condition | Route-specific operations | Include cutting, forming, machining, welding, thermal cutting, heat treatment, blasting, cleaning, coating, and assembly only when performed for the declared part; identify every applicable operation and its exchanges. | us-epa-metal-fabrication-finishing-2008 |
boundary_inventory_completeness | Inputs and outputs | Enumerate each actual bill-of-materials input, energy carrier, process gas, water stream, waste, and direct elementary emission as an atomic exchange; justify and disclose any exclusion. | ec-pef-method-2021 |
boundary_background_links | Purchased inputs | Model upstream production and delivery with appropriate linked datasets rather than duplicating those processes inside the foreground. | ec-pef-method-2021 |
Allocation rules · 4
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_subdivision | Shared fabrication, finishing, and utility processes | Prefer direct metering or subdivision by part family, production order, machine time, or batch so inputs and outputs attributable to the declared part are isolated. | ec-pef-method-2021 |
allocation_physical_relationship | Shared processes that cannot be subdivided | Allocate using a documented causal physical relationship such as machine time, coating area, weld length, treated mass, or accepted output mass that represents the shared process driver. | ec-pef-method-2021 |
allocation_economic_fallback | Shared processes lacking a defensible physical relationship | Use economic allocation only as a documented fallback, disclose prices, period, currency, and sensitivity, and do not use it to hide missing production records. | ec-pef-method-2021 |
allocation_scrap_treatment | Metal scrap and other wastes | Report waste mass and treatment destination separately; do not assign an avoided-burden credit inside this gate-to-gate foreground unless the governing downstream study method explicitly requires and documents it. | ec-pef-method-2021 |
