5.12.4.3 Test fixture
The test fixture annular rings shall have a dimensional tolerance of ±1.5 mm (±0.06 in). Material for the
test fixture should be 0.75 mm (0.03 in) thick Type 304 stainless steel.
5.12.4.4 Other test conditions
Other test conditions shall be as follows:
a) the upstream pressure tap shall be located 200 ± 50 mm (8 ± 2 in) upstream of the specimen inlet;
b) the pressure tap size and configuration shall comply with ASME PTC 19.2 or ANSI/ISA-75.02;
c) if a fluid meter is used to measure the flow rate, the installation shall be in accordance with
ASME PTC 19.5;
d) if the volume/time method is used for the flow rate measurement, the container shall be of
sufficient size to hold water collected for at least 1 min;
e) the water temperature shall be 38 ± 6 °C (100 ± 10 °F) and shall be maintained for at least 1 min;
and
f) the flowing pressure shall be 310 ± 7 kPa (45 ± 1 psi) at the inlet.
5.12.4.5 Test procedure
The test procedure shall be as follows:
a) mount the specimen so that its faceplate is horizontal and parallel with the top surface of the
annular rings;
b) position the annular rings underneath the specimen so the centreline of the faceplate and the
centre ring are in vertical alignment and the top of the annular gauge is 450 ± 6 mm (18 ± 0.25 in)
from the faceplate (see Figure 12);
c) cover the top of the annular rings and adjust the flowing pressure until stabilized;
d) remove the cover and allow the water to flow through the specimen and into the annular rings for
at least 1 min;
e) record the measured flow rate and, using a stopwatch, the time to the nearest second;
f) collect, measure, and record the volume of water in each annular ring and determine the total
volume collected in all of the rings;
g) calculate and record the percentage collected in each ring relative to the total recorded volume
collected; and
h) if the total volume collected varies by more than ±5% of the total volume calculated from the
recorded flow rate and time, repeat the procedure.
5.13 High-efficiency commercial pre-rinse spray valves
5.13.1 General
High-efficiency commercial pre-rinse spray valves shall comply with Clauses 5.13.2 to 5.13.3.
In accordance with Clause 4.18.1, if the commercial pre-rinse spray valve has more than one mode, the
manufacturer shall specify the mode or modes that are intended to comply with the high-efficiency
requirements.
5.13.2 Flow rate
The maximum flow rate for high-efficiency commercial pre-rinse spray valves shall be specified by the
manufacturer, but in no case shall be more than 4.85 L/min (1.28 gpm), verified through testing in
accordance with Clause 5.4.3.
