Before the cycling test described below, the components shall be subjected to a hydraulic test pressure of 1,5 times nominal working pressure or maximum allowable working pressure as applicable. The components shall not show signs of permanent deformation or visible leaks.
The components shall be subjected to 3 times the number of filling cycles or duty cycles calculated in accordance with section 2.7.6. or 2.7.7.
The pressure shall periodically change from 2,0 MPa to 1,25 times nominal working pressure for components upstream of the first pressure regulator, or from 0,1 times MAWP to MAWP for components downstream of the first pressure regulator, at a rate not exceeding 6 cycles per minute.
Subsequently the component shall fulfil the requirements of the internal and external leakage tests (sections 4.2.4. and 4.2.5.).
