Final acceptance

Is carried out before delivery to the customer depending on the classification of the pressure equipment. Here, pressure equipment is to be subjected to the acceptance process as described below.

a) Final inspection
Pressure equipment must be subjected to a final inspection, where a visual inspection and test of the related documentation is to be carried out in order to check that the requirements of this guideline are fulfilled. In doing so, inspections carried out during manufacturing may be taken into account. If required for safety reasons, the final inspection of the inside and outside of all parts of the equipment must be carried out during the manufacturing process (e.g. if testing during final inspection is no longer possible).

b) Pressure test
The acceptance of the pressure equipment must also include a pressure strength test which is normally carried out in terms of a hydrostatic pressure test where the pressure for this is clearly specified.  For equipment of the category I manufactured in series this inspection can be carried out on a statistical basis. If the hydrostatic pressure test is disadvantageous or infeasible, other tests can be carried out which have proven effective. For tests other than the hydrostatic pressure test, additional measures such as non-destructive tests and other equivalent procedures must be used first.

c) Testing safety equipment
For components, the acceptance must also comprise a test of the equipment parts with a safety function, whereby it must be tested that the requirements have been fully satisfied.
