AS 3558.10-1999 (R2016) pdf free.Methods of testing plastics and composite materials sanitary plumbing fixtures – Method10:Determination of thermal expansion under load of laundry troughs.
This Standard sets out a method for determining the limits of thermal expansion under load
of plastics laundry troughs.
The trough is mounted in accordance with the installation instructions. Marks are scribed on the trough at room temperature and measurements are taken. Hot water is run into the trough and the measurements are retaken.
The following apparatus is required:
(a) Scriber.
(h) Temperature gauge.
(c) Measuring tape.
The procedure shall he as follows:
(a) Mount the trough in accordance with the manufacturer’s instructions supplied with the trough.
(b) Scribe marks (AK, BB’, CC’, and DD’) on the flange of the trough as shown in Figure 1(a), and record the distances AC and BD at room temperature.
(c) Run hot water at 90 ±2°C into the trough through an inlet pipe discharging at a rate of 15 ±2 L/min until the trough contains water to a depth of at least two-thirds of the spill level (see Figure 1(b)).
(d) Measure the water temperature at a water depth of between i mm and 50 mm. When the water temperature is in the range of 80°C to 85°C, measure the distance between the opposite pairs of scribed marks.
