c) for maximum flow for low-pressure water dispensers: at 105 kPa ± 7 kPa (15 psi ± 1 psi) at the inlet
when water is flowing.
5.4.2.3.2
Flow rate tests for showerheads, body sprays, and hand-held showers shall be conducted with water at
38 ± 6 °C (100 ± 10 °F) and the flow maintained for at least 1 min. The flow rate test for
a) maximum
flow for showerheads shall be conducted at 550 ± 14 kPa (80 ± 2 psi);
b) minimum
flow for showerheads and hand-held showers shall be conducted at 310 ± 14 kPa (45 ±
2
psi).
If the showerhead or hand-held shower has more than one mode, the minimum flow
rate
shall
be determined at a flowing pressure of 310 ± 7 kPa (45 ± 1 psi) in all modes. Pause or
trickle
modes
designed to flow at less than 1.9 L/min (0.5 gpm) at 550 kPa (80 psi) shall be excluded fr
om
the
minimum flow requirements;
and
Note: The intent of Item b) is to aid in the selection of an appropriate automatic compensating valve.
c) high-efficiency showerheads and hand-held showers shall be conducted in accordance with
Clause 5.12.2.
5.4.3 Test procedure for high-efficiency commercial pre-rinse spray valves
5.4.3.1 Specimens
Three production models shall be selected for testing.
5.4.3.2 Testing
The flow rate of pre-rinse spray valves shall be tested in accordance with the procedures in ASTM F2324
with the exception of Appendix XI.
5.5 Operating requirements
5.5.1
Except for accessible designs and tub-to-shower and tub spout diverters, the torque or force required to
open, operate, and close a manually activated valve or operating control shall not exceed the applicable
operating torque or linear force specified in Table 2 when the manually operated valve or operating
control is tested at the temperatures and pressures specified in Clause 5.3.1.4.
5.5.2
Accessible design devices shall be tested in accordance with Clause 5.3.1.4.1. Before and after the life
cycle test, the linear force required to open, operate, and close a manually activated valve or operating
control shall not exceed
a) 22
N (5 lbf) when tested
at
i) 140
± 14 kPa and 10 ± 6 °C (20 ± 2 psi and 50 ± 10 °F);
ii) 550
± 14 kPa and 10 ± 6 °C (80 ± 2 psi and 50 ± 10 °F);
iii) 140
± 14 kPa and 66 ± 6 °C (20 ± 2 psi and 150 ± 10 °F); and
iv) 550
± 14 kPa and 66 ± 6 °C (80 ± 2 psi and 150 ± 10 °F); and
b) 45
N (10 lbf) when tested in accordance with Items b) and d) of Clause 5.3.1.4.2.
5.5.3
Low-pressure water dispensers shall be tested at a flowing pressure of 140 ± 14 kPa (20 ± 2 psi), with
water at 10 ± 6 °C (50 ± 10 °F) for cold water only applications or with water at 99 + 0, –6 °C
(210 +0, –10 °F) for hot water only applications. Devices intended to dispense cold and hot water shall
