c) Conduct the test in accordance with Clause 5.9.3.2.3.6.
5.9.3.2.3.5 Test set-up
The specimen shall be set up as follows:
a) Mount the specimen in its normal operating position, in accordance with the manufacturer’s
instructions and using the test set-up shown in Figure 6.
b) Connect the inlet pipe(s) collectively to a water supply that can deliver water through the specimen
at normal flow and to the atmosphere.
c) Connect a pressurized water supply, as shown in Figure 6, to the specimen outlet in a leak-proof
manner.
5.9.3.2.3.6 Test procedure
The check valve leakage test shall be conducted as follows (see Figure 6):
a) Mount the specimen in accordance with Clause 5.9.3.2.3.5.
b) Seal all atmospheric vents.
c) Open Valve 1 and purge the air from the system.
d) Close Valve 1.
e) Open Valve 2 to reduce the water pressure on the inlet side to 0.
f) Gradually raise the outlet pressure to 1.4 kPa (0.2 psi).
g) Isolate the pressure source for 5 min.
h) Increase the outlet pressure to 35 kPa (5 psi).
i) Isolate the pressure source for 5 min.
5.9.3.2.4 Adequacy of the atmospheric vent
5.9.3.2.4.1 General
For fittings incorporating an atmospheric vent, the adequacy of the atmospheric vent shall be verified
by performing the test specified in Clause 5.9.3.2.4.3.
5.9.3.2.4.2 Performance requirements
The maximum allowable rise in water level in the sight tube shall be to within ±25 mm (±1.0 in) of the
critical level of the device when the test is performed as specified in Clause 5.9.3.2.4.3.
Note: The location of the critical level of the device may be determined in accordance with Clause 16 of
ASME A112.18.3.
5.9.3.2.4.3 Test procedure
The test for verifying the adequacy of the atmospheric vent shall be conducted as follows:
a) Connect a sight tube in a leak-proof manner to the outlet of the specimen.
b) Foul all check valves with a 0.81 mm (0.032 in) wire.
c) Leave the atmospheric vents open.
d) Install the specimen in accordance with Clause 5.9.3.2.2.3.
e) Conduct the test in accordance with Clause 5.9.3.2.2.4.
5.9.3.3 Back siphonage prevention in side spray diverters
5.9.3.3.1 General
Fittings incorporating a side spray diverter shall comply with the performance requirements of
Clause 5.9.3.3.2 when tested in accordance with Clause 5.9.3.3.3.
