5.3 Pressure and temperature
5.3.1 Static and dynamic seals
5.3.1.1 Failure criteria
Seals of plumbing supply fittings and accessories, except those of automatic compensating valves (see
Clause 4.15), shall not leak or otherwise fail when tested in accordance with Clauses 5.3.1.2 to 5.3.1.4.
5.3.1.2 Procedure with the valve closed
The specimen shall be tested in accordance with Clause 5.3.1.4, after which it shall be subjected to the
supply pressures specified in Clause 5.3.1.4, for 5 min each, with the valve closed.
5.3.1.3 Procedure with the outlet(s) blocked
The specimen shall be tested in accordance with Clause 5.3.1.4, after which it shall be subjected to the
supply pressures specified in Clause 5.3.1.4, for 5 min each, with the outlet(s) blocked.
Where the outlet(s) is difficult to block, the flowing pressure shall be increased to the pressures
specified in Clause 5.3.1.4, for 5 min each. The joints of the fittings shall be checked for leakages.
5.3.1.4 Test temperatures and pressures
5.3.1.4.1
The test shall be conducted in an ambient environment of 20 ± 5 °C (68 ± 9 °F). The specimen shall be
brought to equilibrium test temperatures by running water through it.
5.3.1.4.2
The test temperatures and pressures shall be as follows:
a) 140 ± 14 kPa and 10 ± 6 °C (20 ± 2 psi and 50 ± 10 °F);
b) 860 ± 14 kPa and 10 ± 6 °C (125 ± 2 psi and 50 ± 10 °F);
c) 140 ± 14 kPa and 66 ± 6 °C (20 ± 2 psi and 150 ± 10 °F); and
d) 860 ± 14 kPa and 66 ± 6 °C (125 ± 2 psi and 150 ± 10 °F).
Devices intended only for cold water applications shall be tested in accordance with Items a) and b)
only.
5.3.2 Burst pressure
5.3.2.1 Failure criteria
Fittings shall withstand a hydrostatic burst pressure test at the pressures specified in Clause 5.3.2.2 or
5.3.2.3, without permanent distortion or failure of the pressure envelope.
5.3.2.2 Terminal fittings
Terminal fittings shall withstand a hydrostatic pressure of 3450 kPa (500 psi) for 1 min. The pressure
shall be applied to the inlet with the valve(s) closed. Fittings may be of the pressure-relieving type,
provided that the relief occurs at a pressure above 1030 kPa (150 psi) and the relief discharge is into the
fixture.
