Division 4.2.1.2 Procedure

The container shall be hydraulically burst tested at ambient temperature using the following procedure:

The rate of pressurisation shall be ≤ 1,4 MPa/s for pressures higher than 80 per cent of the nominal working pressure times the burst pressure ratio stated in section 3.6. If the rate exceeds 0,35 MPa/s at pressures higher than 80 per cent of the nominal working pressure times the burst pressure ratio, then either the container shall be placed in series between the pressure source and the pressure measurement device, or the time at pressure above the nominal working pressure times the burst pressure ratio shall exceed 5 seconds.
