5.9.3.3.2 Performance requirements
During testing in accordance with Clause 5.9.3.3.3, water shall not rise in the sight tube except for an
upward bowing of the meniscus of not more than 3 mm (0.12 in).
5.9.3.3.3 Test procedure
The test shall be conducted as follows (see Figure 5):
a) Remove the spray head.
b) Connect a sight tube in a leak-proof manner to the spray hose outlet of the specimen.
c) Install the specimen in accordance with Clause 5.9.3.2.2.3.
d) Open Valve 1.
e) Flush the specimen with water for 5 min.
f) Close Valve 1.
g) Open Valve 2 to the atmosphere and allow water to drain from the device and from the hose.
h) Conduct the test in accordance with Clause 5.9.3.2.2.4.
5.9.3.4 Service sink faucets
Service sink faucets shall be designed to prevent re-installation of the spout directly onto the faucet
body with the backflow prevention device removed, when the faucet has a backflow prevention device
that
a) is
not cast in the body of the faucet;
b) has
an inlet in line with its outlet; and
c) has
a disassembly torque of less than 81 N·m (60 lbf·ft).
5.10 Lawn faucets
5.10.1 Performance requirements
When tested in accordance with Clause 5.10.2, lawn faucets shall drain at least 50% of the volume of
the inlet shank and pipe.
5.10.2 Test procedure
Lawn faucets shall be tested as follows:
a) Connect the faucet to a 1.2 m (48 in) length of standard-weight pipe of the same nominal diameter
as the inlet of the faucet.
b) Install the assembly (faucet and pipe) with a downward slope of 1% toward the faucet.
c) Close the faucet, fill the assembly with water, and measure the amount of water required to fill the
assembly.
d) Open the faucet and allow the assembly to drain for 5 min, collecting the water that drains.
e) Measure the amount of water drained.
5.11 Alternative materials test
5.11.1 Performance requirements
Coupling nuts, locknuts, and spout-holding nuts shall not be adversely affected when tested in
accordance with Clause 5.11.2. Fittings shall be capable of being disassembled and reassembled and
continue to comply with Clause 5.3.1.
