3 3 Range of products  pressure vessels  boilers  piping  safety accessory (e.g. safety valve)  pressure accessory (e.g. isolating valve)  assemblies (e.g. fire extinguisher)

4 4 Pressure vessel  housing designed and built to contain fluids under pressure  vessel may be composed of more than one chamber (e.g. heat exchanger)

5 5 Boiler  intended for generating steam, hot or warm water  consists of several parts (body, evaporator, preheater, economizer etc.)

6 6 Piping  components intended for the transport of fluids  piping includes in particular a pipe or system of pipes, tubing, fittings, expansion joints, hoses, or other pressure - bearing components as appropriate

7 7 Safety accesory  devices designed to protect pressure equipment against the allowable limits being exceeded (pressure, temperature, volume, flow)

8 8 Pressure accesory  device with an operational function and having pressure - bearing housing  valve, water gauge, etc.

9 9 Assembly  several pieces of pressure equipment assembled by a manufacturer to constitute an integrated and functional whole  they are integrated, i.e. they are connected and designed to be compatible with each other and  they are functional, i.e. together, they achieve specific, overall objectives and could be put into operation, and  they form a whole, i.e. all the items which are necessary for the assembly to function and be safe are present and  they are assembled by one manufacturer who intends the resulting assembly to be placed on the market and who will subject the assembly to a global conformity assessment procedure
