This test shall be carried out at ambient temperature on coated products on at least one DN by type of SML fitting and by group of DN defined in Table 9.
The test assembly shall be capable of providing water tightness and lateral restraint on each end of the fitting for the required internal hydrostatic pressure. Sealing of the fittings ends can be with blank ends with couplings, plates with rubber seal, expansion plugs, etc. to ensure a leak tight seal and permit suitable end restraint.
1. Access 2. Door 3.Joints+grip Collars
The test assembly shall be filled with water and suitably vented of air. The hydrostatic pressure shall be raised steadily and held at every stage in accordance with Table 11, until it reaches the test pressure given in Table 2. Throughout the duration of the test, all necessary safety precautions have to be taken; the fitting shall show no leakage in the area of the access or the door.
