1. Scope and Applicability
This PCR covers cradle-to-factory-gate production of complete stationary, marine, and other non-aircraft gas turbines that convert fuel energy into mechanical shaft output. It includes purchased materials and components, directly controlled casting where performed, heat treatment, joining, machining, protective coating, assembly, inspection, and manufacturer acceptance testing when it occurs before the factory gate.
Turbo-jets, turbo-propellers, steam turbines, hydraulic turbines, generators, complete combined-cycle plants, site civil works, installation, distribution, use, maintenance, overhaul, and end-of-life are excluded. An aero-derivative unit is covered only when marketed as a non-aircraft mechanical-drive or power-generation gas turbine; the aircraft engine from which it derives is not covered. The product boundary is independently justified by the official CPC identity and by the distinct materials, manufacturing controls, and acceptance-test needs of industrial gas turbines.

|---|---|---|---|
allocation_subdivide_first | shared manufacturing and test operations | First subdivide meters, work orders, test logs, and waste records by product family, batch, or serial number whenever physically possible. | eu-pef-recommendation-2021-2279 |

allocation_economic_last_resort | inseparable multi-product operations | Use economic allocation only when no defensible physical relationship exists; disclose prices, period, currency, volatility treatment, and sensitivity. | eu-pef-recommendation-2021-2279 |
allocation_scrap | metal scrap and recovered process material | Internally reused material does not cross the process boundary. Record material leaving the foreground as waste without avoided-burden credit; downstream recycling treatment belongs to the receiving system unless the study explicitly expands the boundary. | eu-pef-recommendation-2021-2279 |

System boundary rules · 3
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
boundary_cradle_to_gate | foreground and upstream product system | Include upstream production of every recorded input and all directly controlled manufacturing, assembly, inspection, and applicable acceptance testing through the unpackaged factory-gate reference product. | eu-pef-recommendation-2021-2279, us-doe-netl-gas-turbine-handbook-2006-buckets-nozzles |
boundary_no_silent_cutoff | process and flow completeness | Do not omit a process or exchange merely because a UUID or preferred dataset is unavailable. Any applied cut-off shall be quantified, justified across material, energy, and environmental significance, and disclosed. | eu-pef-recommendation-2021-2279 |
boundary_use_excluded | downstream life cycle | Exclude installation, operation, maintenance, overhaul, and end-of-life from the reported cradle-to-gate inventory; report design-life and use assumptions only as metadata for downstream models. | eu-pef-recommendation-2021-2279 |
Allocation rules · 4
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_subdivide_first | shared manufacturing and test operations | First subdivide meters, work orders, test logs, and waste records by product family, batch, or serial number whenever physically possible. | eu-pef-recommendation-2021-2279 |
allocation_physical_causal | inseparable shared operations | If subdivision is not possible, use a documented causal physical driver such as machine time, furnace occupancy, treated area, test duration, or measured product mass; demonstrate why it represents resource use. | eu-pef-recommendation-2021-2279 |
allocation_economic_last_resort | inseparable multi-product operations | Use economic allocation only when no defensible physical relationship exists; disclose prices, period, currency, volatility treatment, and sensitivity. | eu-pef-recommendation-2021-2279 |
allocation_scrap | metal scrap and recovered process material | Internally reused material does not cross the process boundary. Record material leaving the foreground as waste without avoided-burden credit; downstream recycling treatment belongs to the receiving system unless the study explicitly expands the boundary. | eu-pef-recommendation-2021-2279 |
