S Testing
5.1 Installation
Hydromassage bathtub systems shall be installed in accordance with the manufacturer’s instructions.
When installation tolerances are specified, the hydromassage system shall be tested in the least favourable
slope foi drainage, but within the manufacture?s specifications.
5.2 Water retention in whirlpool or air-jetted bathtubs
5.2.1 General
Water retention in whirlpool or air-jetted bathtubs may be evaluated using the chlorine test specified in
Clause 5.2.4 or the volumetric test specified in Clause 5.2.5.
5.2.2 Preconditioning
The specimen shall be preconditioned as follows:
(a) Fill the specimen with water at 57 ± 3 °C (1 35 ± 5F) until the jets are completely covered and it can he properly operated.
(b) Circulate the water for 2 hr ± 10 mm and ensure that the water temperature is maintained at not less than 54 0C (1 3OF).
(c) Drain the specimen and allow it to cool to ambient temperature.
5.2.3 Performance
Hydromassage bathtubs shall not allow retention of water in excess of 44 mL (1.5 fI oz) for each jet and
suction fitting. The water retention for air-jetted hydromassage bathtubs shall not exceed 400 mL
(1 3.5 fI oz), regardless ol the number of air jets. Sampling shall be performed in accordance with Annex B. For combination whirlpool and air-jetted bathtubs, the water volumes shall be cumulative.
A whirlpool bathtub with four jets and one suction fitting shall be considered to satisfy the requirements of this Clause ii the residual water does not exceed 220 mL (7.5 fi oz).
The maximum residual water in combination four jet, one suction fitting whirlpool and air-jetted bathtubs shall be 620 ml (21 fI oz).
5.2.4 Chlorine test
5.2.4.1
The following requirements shall apply:
(a) The procedure shall be conducted within a 1 h time interval.
(b) The quality of the water used in the chlorine method shall have a total organic content no greater than 5 mg/L and a pH between 6 and 8, with the pH variation during the test no greater than ±0.1.
(c) The original chlorine level shall be accurately measured to within ±0.05 mgJL. recorded, and factored out of the test reading.
