4.2.2
When used, atmospheric vacuum breakers shall
(a) comply with CLause 5.5.1; and (b) be installed with the
(i) critical level located not less than 25 mm (1 in) above the flood level rim; or
(ii) lowe5t point located not less than 25 mm (1 in) above the flood level rim, when the critical level is not marked,
4.3 Electrical components
Personal hygiene devices with electrical features or components shall comply with UL 1431, CSA C22.2
No. 68, or CSA C22.2 No. 64.
4.4 Plastic toilet seats
Plastic toilet seats shall comply with IAPMO/ANSI Z124.5.
4.5 Bidet sprayers
Bidet sprayers shall be
(a) fully retractable and not subject to contamination in the retracted position, (i.e., be completely removed from the liquid and solid waste path);
(b) self-cleaning, (i.e., have a means to rinse the bidet sprayer with water); and
(C) concealed when not in use to prevent soiling by the user.
4.6 Source of water
The water from the water closet tank shall not be used as a source of water for the bidet sprayer.
4.7 Automatic seat cover dispensers
Automatic seat cover dispensers shall be life cycle tested in accordance with Clause 5.6.
4.8 Temperature safety device
Personal hygiene devices shall be equipped with a safety device to shut off the flow of water when the temperature reaches 48 C (11 8’F).
5 Perforniance requirements and test procedures
5.1 Order of tests
The tests shall be conducted in the order in which they appear in this Standard.
5.2 Bidet spray pressure tests
5.2.1 Flowing pressure test
5.2.1.1 Test procedure
The flowing pressure test shall be conducted as follows:
(a) Connect the specimen to a water supply.
(b) Increase the flowing pressure to 860 kPa (125 psi), measured at the specimen inlet.
(c) Allow the water flow through the specimen for S mm.
(d) Inspect For leakage and structural damage.
5.2.1.2 Performance requirements
There shall be no leakage. Flow from the bidet sprayer shall be as intended by the manufacturer.
5.3.1.1Test procedure
The normal operating temperature test shall be conducted as follows:(a) Set the inlet flowing pressure at 345土 35 kPa(50± 5 psi).
(b)Set the inlet temperature at 18土 3 C(65 ±5F).
(cOperate the specimen at its maximum temperature setting for 5 min.(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 Maximum shutoff temperature for safety devices5.3.2.1 Test procedure
The maximum shutoff temperature test shall be conducted as follows:
(a) Supply water to the specimen at an initial temperature of 41+0/-6 °℃(105 +0/-10F).
(b) set the inlet flowing pressure at 345土 35 kpa (50 ± 5 psi) pressure.
(c)Activate the specimen and slowly raise the temperature to 48 C (118F).
(d)Increase the water temperature no faster than 0.5 C(1F) every 5 s.
(e)Record the time to shut off the flow of water when the temperature reaches 48 °C(118°F). Repeat this test following the bidet sprayer cycle test.
