5.2.2 Static pressure test
5.2.2.1 Test procedure
The static pressure test shall be conducted as follows:
(a) Set the specimen in the off position (fully closed).
(b) Increase the static water pressure to 1 720 kPa (250 psi).
(c) Maintain the pressure for 5 mm.
5.2.2.2 Performance requirements
There shall be no leakage or structural damage.
5.3 Temperature tests
5.3.1 Normal operating temperature test
5.3.1.1 Test procedure
The normal operating temperature test shall be conducted as follows:
(a) Set the inlet flowing pressure at 345 ± 35 kPa (50 ± 5 psi).
(b) Set the inlet temperature at 18 ± 3 °C (65 ± 5°F).
(c) Operate the specimen at its maximum temperature setting for 5 mm.
(d) Measure the temperature at the outlet.
5.3.1.2 Performance requirement
The water temperature at the outlet shall not exceed 43 °C (110°F).
5.3.2 Maxiniuni shutoff temperature for safety devices
5.3.2.1 Test procedure
The maximum shutoff temperature test shall be conducted as follows:
(a) Supply water to the specimen at an initial temperature of 41 +01—6 °C (105 +0/—10°F).
(b) Set the inlet flowing pressure at 345 ± 35 kPa (50 ± 5 psi) pressure.
(c) Activate the specimen and slowly raise the temperature to 48 °C (118°F).
(d) Increase the water temperature no faster than 0.5 °C (1°F) every 5 s.
(e) Record the time to shut off the flow of water when the temperature reaches 48 °C (118°F).
(1) Repeat this test following the bidet sprayer cycle test.
5.3.2.2 Performance requirements
The water flow through the specimen shall shut off within 5 s of the bidet spray discharge water temperature reaching 48 °C (118°F). Water may continue to flow from the bidet sprayer discharge as long as the temperature remains below 48 °C (118°F) and the sprayer is in the process of returning to its off position/state. The specimen shall be considered to have complied with the requirements of this Clause if water ceases to flow prior to reaching a temperature of 48 °C (118°F),
5.4 Bidet sprayer life cycle test
5.4.1 Test procedure
The life cycle test shall be conducted as follows:
(a) Set the inlet flowing pressure at 345 ± 35 kPa (50 ± 5 psi).
(b) Set the device to its maximum water temperature setting.
(c) Operate the specimen 75,000 times:
(i) At each cycle, the bidet sprayer shall fully extend and then fully retract.
(ii) For specimens with multiple bidet sprayers, the anterior (front) sprayer shall be tested for 50,000 cycles and the posterior (rear) sprayer shall be tested for 25,000 cycles.
5.4.2 Performance requirements
At the end of the life cycle test, the specimen shall continue to function at the operating pressure as it did before the test. In addition, there shall be no leakage, and the flow from the bidet sprayer shall be as intended by the manufacturer.
5.5 Atmospheric vacuum breaker test
5.5.1 Test procedure
Vacuum breakers shall be tested for back siphonage in accordance with ASSE 1001 or CSA B64.1.1.
5.5.2 Performance requirements
Water in the sight tube shall not rise more than 1 3 mm (0.5 in).
5.6 Seat cover dispenser test
5.6.1 Test procedure
The seat cover dispenser shall be operated for 5,000 cycles. Each cycle shall consist of dispensing one seat cover.
5.6.2 Performance requirements
Failure to dispense the seat cover in 100 or more of the 5,000 cycles shall be cause for rejection.
Continuous feed dispensers shall render previously dispensed seat covers unusable.
5.7 Bidet sprayer self-cleaning test
5.7.1 lest procedure
The self-cleaning test shall be conducted as follows:
(a) Operate the bidet sprayer enough cycles to ensure that it is purged of air and filled with water at normal operating pressure and temperature.
(b) Extend the bidet sprayer and dry it thoroughly.
(c) Use a water-soluble marker of a contrasting colour to draw lines on the bidet sprayer as follows:
(i) Draw three rings around the bidet sprayer, one in the upper third of its length, one in the middle third, and one in the lower third.
(ii) Draw a fourth line longitudinally, along the top of the bidet sprayer from one end to the other.
(d) Release the bidet sprayer and allow it to retract into its off position.
(e) The bidet sprayer self-cleaning function shall be actuated two times.
(f) Inspect and record any lines remaining.ASME A112.4.2 pdf download.
