Other electrical equipment n.e.c. (including electro-magnets; electro-magnetic couplings; clutches and brakes; electro-magnetic lifting heads; electrical particle accelerators; electrical signal generators and apparatus for electro-plating, electrolysis or electrophoresis)

1. Scope and Applicability

This PCR governs cradle-to-gate foreground data packages for finished electrical equipment not elsewhere classified within the semantic boundary below. Covered configurations include electromagnets, electromagnetic couplings, clutches and brakes, electromagnetic lifting heads, electrical particle accelerators, electrical signal generators, and apparatus for electroplating, electrolysis, or electrophoresis. Because these products differ materially in function and construction, every data package shall declare one concrete product model or homogeneous product family, bill-of-material state, manufacturing route, rated function, and factory-gate condition.

Permanent metallic magnets and permanent ceramic or ferrite magnets sold as products are excluded because CPC 3.0 identifies them as sibling subclasses. Also excluded are junction boxes, printed wire boards sold separately, electric motors, generators, transformers, batteries, alarms, lighting equipment, and other products covered by a narrower PCR. Use, maintenance, distribution, installation, and end-of-life are outside this factory-gate rule unless the study explicitly adds those stages under a compatible narrower rule. This broad PCR shall not support comparative assertions between unlike equipment functions or lifetime performances.

Required qualifiers	declared product type and model or homogeneous family; rated function and principal performance specification; bill-of-material revision; integral versus separately supplied parts; net-mass determination method; manufacturing site and geography; production technology and route; reporting period; accepted-product test criteria; factory-gate packaging condition

When constructing a foreground data package, every required qualifier shall be declared in metadata, process notes, the reference-flow comment, the product description, or an equivalent field. A missing qualifier makes the reference flow incomplete. No exact public state-100 Tiangong product flow represents this configuration-declared cross-family reference product, so the product-flow UUID remains unresolved; narrower product flows shall not be used as proxies.
