Machinery n.e.c. for the treatment of materials by a process involving a change of temperature

1. Scope and Applicability

This PCR applies to the production of complete non-household machinery, plant, or laboratory equipment whose principal function is to treat material by a temperature-changing operation such as heating, cooking, roasting, sterilising, pasteurising, steaming, drying, evaporating, vaporising, condensing, or cooling, and which is not classified in a more specific machinery category. It supports a foreground manufacturing data package and downstream process or lifecyclemodel projections.

The category is residual. It excludes industrial or laboratory furnaces and ovens classified separately; non-household refrigerating/freezing equipment and heat pumps; air-conditioning machines; distilling or rectifying plant; heat-exchange units; machinery for liquefying air or gas; non-electric water heaters; domestic appliances; parts supplied separately; and special-purpose thermal machinery classified by the industry or material it processes. A data producer shall document why the declared product remains in this n.e.c. boundary.

The default foreground gate covers purchased materials and components entering the manufacturing site through fabrication, assembly, surface preparation where performed onsite, factory acceptance testing, and release of the complete unpackaged machine at the factory gate. Installation, external transport packaging, distribution, use, maintenance, working-fluid charging performed after the factory gate, and end-of-life are outside this production gate unless the declared study explicitly expands the boundary. Downstream life-cycle models shall add those stages when their goal requires them.
