Type: [?]

Type Definitions:

Vessel: A housing designed and built to contain fluids under pressure including its direct attachments up to the coupling point connecting it to other equipment.

Piping: Piping components intended for the transport of fluids, when connected together for integration into a pressure system.

Pressure accessory: Devices with an operational function and having pressure-bearing housings, such as valves, pressure regulators, measurement chambers, pressure gauges, water gauge glasses, filters, expansion joints and manifolds.

Steam generator: Fired or otherwise heated vessels or piping with the risk of overheating that are intended for generation of steam or super-heated water at maximum allowable temperatures > 110° C having a volume greater than 2 liters, and all pressure cookers.

Safety accessory: Devices designed to protect pressure equipment against the allowable limits being exceeded.

Assembly: Several pieces of pressure equipment assembled by a manufacturer to constitute an integrated and functional whole.

Fluid: [?]

Fluid Definitions:

Gas: Substances with a vapor pressure over 0.5 bar above normal atmospheric pressure (1013 mbar) at their highest allowed temperature.

Liquid: Substances with a vapor pressure of 0.5 bar or less above normal atmospheric pressure at their highest allowed temperature.
