Other hydraulic and pneumatic power engines and motors

1. Scope and Applicability

This PCR governs foreground data packages for assembly and factory acceptance testing of complete non-linear-acting hydraulic or pneumatic power engines and motors, including continuous-rotation motors and limited-rotation actuators. The reporting organization shall declare the working medium, operating principle, rated performance, service-life basis, bill of materials, and test route. The foreground begins with inspected product-specific components or subassemblies at the assembly-site gate and ends with one accepted, market-ready, unpackaged motor at the factory gate. Purchased components and energy carriers require separate upstream datasets.

Excluded are linear-acting cylinders in CPC 43211, hydraulic turbines and water wheels, pumps, compressors, valves, electric motors, internal-combustion engines, incomplete parts, distribution, use, maintenance, and end-of-life. The CPC source establishes the residual classification boundary; manufacturer technical information supports representative hydraulic and pneumatic functions and component architecture.
