b) multi-function aerators;
c) shampoo diverters;
d) showerhead adjustment mechanisms;
e) showerhead flow or function controls; and
f) side spray flow or function controls.
5.6.3.3.2
The following devices shall be tested at a flowing pressure of 345 ± 35 kPa (50 ± 5 psi) at 9.5 ± 0.4 L/min
(2.5 ± 0.1 gpm) through a fixed outlet or with their standard accessories installed, when installed at a
maximum distance of 2.0 m (78 in) from the outlet of the diverter:
a) in-line
flow-control devices in showers;
b) shower
-to-shower diverters;
c) tub
spout diverters; and
d) tub-to-shower
diverters.
5.6.3.3.3
For tub-to-shower diverters and tub-spout diverters, the specimen shall be mechanically activated to
deliver full flow through the outlet. The flow of water shall be shut off by a bath or shower supply fitting
or control valve installed upstream of the specimen. Diverters shall be reset to the tub position
mechanically except for automatic diverters, which are intended to reset themselves to the tub
position. The test apparatus for automatic diverters may relieve the showerhead flowing pressure while
simultaneously shutting off the supply valve to accelerate the life cycle test.
5.6.3.3.4
One complete cycle for a device shall consist of switching the device from one position to the other and
back to the original position. In the case of devices with multiple adjustable positions, one complete
cycle shall consist of switching from one extreme position, through all the intermediate positions, to the
other extreme position and back to the original position.
5.6.3.3.5
For showerhead, body spray, and hand-held shower assembly ball joints, one complete cycle shall
consist of moving the device horizontally from an initial full-side position to the opposite full-side
position and back to the initial-side position without making contact with surfaces at the extreme ends
of the path.
5.6.3.4 Swing spouts
The life cycle test for swing spouts shall be conducted as follows:
a) Mount the specimen on the life cycle test apparatus with the axis about which the spout turns
mounted vertically and in line with the axis of the drive spindle.
b) Fit the forked end of the drive adapter loosely over the spout and allow the spout tip to freely
move vertically.
c) Attach a weight with a mass of 0.18 kg (0.40 lb) to the spout outlet connection.
d) Adjust the apparatus to turn the spout through an equal arc on each side of the centre through
90% of the total path and not more than 90°.
e) Establish and maintain sufficient force to rotate the spout throughout the test, but do not exceed
45 N (10 lbf) applied at the end of the spout.
f) Alternate cold and hot water every 1000 cycles, starting with cold.
