1. Scope and Applicability
This PCR applies to factory production of finished parts designed principally for hydraulic turbines or water wheels and to dedicated turbine governing equipment (regulators or governors). Covered products include runner and blade parts, guide and regulating parts, shafts and housings when supplied as dedicated hydraulic-turbine parts, and mechanical, hydraulic, electrohydraulic, or electronic governing units supplied as CPC 43154 products.
The foreground boundary begins with received materials, blanks, purchased components, consumables, and packaging at the manufacturing site and ends with a conforming finished part or regulator released at the factory gate. Upstream production is represented by linked supplier or background datasets. The PCR excludes complete hydraulic turbines and water wheels, generators, civil works, penstocks, site erection, transport after the factory gate, use, maintenance, repair, and end-of-life. A generic fastener, valve, pump, electronic device, or metal product is excluded unless it is supplied and documented as a dedicated part of the covered goods.
The category is heterogeneous. The foreground data package shall identify the exact part or regulator, its material and manufacturing route, and every process that is applicable. It shall not average mechanically dissimilar part families or regulator designs unless the declared product mix, output mass, allocation, and variability are reported.
