Design begins with a need to acquire pressure equipment. Both general and specific requirements apply to design pursuant to the statutes and standards concerning pressure equipment. Moreover, established sector-specific requirements may apply to pressure equipment and these shall be observed in design. Industrial pressure equipment mostly consists of assemblies to be constructed on-site at a facility or on a property and the commissioning party usually places special requirements on the pressure equipment therein. Delivery specifications are used to prepare a report on the hazards relating to the pressure equipment and assembly, which is then used as the foundation for determining the key safety requirements to be applied in design and manufacture. The design stage results in the technical documentation of the pressure equipment.
Depending on the conformity assessment procedure (modules) prescribed in the statutes on pressure equipment, the technical documentation relating to design is inspected either by the manufacturer or a notified body.
Tukes attends to market supervision concerning the design of pressure equipment.
