# The Pressure Equipment (Safety) Regulations 2016, Paragraph 27: Proof test


(1) Final assessment of pressure equipment must include a test for the pressure containment aspect, which will normally take the form of a hydrostatic pressure test at a pressure at least equal, where appropriate, to the value laid down in paragraph 40.
(2) For category I series-produced pressure equipment, the test referred to above may be performed on a statistical basis.
(3) Where the hydrostatic pressure test is harmful or impractical, other tests of a recognised value may be carried out provided that additional measures, such as non-destructive tests or other methods of equivalent validity, must be applied before such other tests are carried out.
