AS 7240.15:2018 pdf free.AD / 440.10.2010 Australian Standard  Fire detection and alarm systems Part 15: Point type fire detectors using smoke and heat sensors (ISO 7240- 15:2014, MOD).
5.1.1.2 The temperature and humidity shall be substantially constant for each environmental test where the standard atmospheric conditions are applied.
5.1.2 Mounting arrangements
Mount the specimen by its normal means of attachment in accordance with the manufacturer’s instructions. If these instructions describe more than one method of mounting, then the method considered to be most unfavourable for each test shall be chosen.
5.1.3 Operating conditions for tests
5.1.3.1 If a test method requires a specimen to be operational, then connect the specimen to suitable supply and monitoring equipment having the characteristics required by the manufacturer’s data. Unless otherwise specified in the test method, set the supply parameters applied to the specimen within the manufacturer’s specified range(s) and maintain them substantially constant throughout the tests. The value chosen for each parameter shall normally be the nominal value, or the mean of the specified range. If a test procedure requires a specimen to be monitored to detect any alarm or fault signals, then connect the specimen to any necessary ancillary devices (e.g. through wiring to an end-of-line device for non- addressable detectors) to allow a fault signal to be recognized.
5.1.3.2 The details of the supply and monitoring equipment and the alarm criteria used shall he given in the test report (Clause 6).
5.1.4 Tolerances
5.1.4.1 (inless otherwise stated, the tolerances for the environmental test parameters shall be as given in the basic reference standards for the test (e.g. the relevant part of IEC 60068).
5.1.4.2 If a specific tolerance or deviation limit is not specified in a requirement or test procedure, then a tolerance of ±5 % shall be applied.
5.1.5 Measurement of the smoke-response value
5.1.5.1 Install the specimen for which the smoke-response value, Asr, is to be measured in a smoke tunnel, described in Annex B, in its normal operating position, by its normal means of attachment. The orientation of the specimen, relative to the direction of airflow, shall be the least sensitive orientation as determined in the directional dependence of smoke response test (5.3), unless otherwise specified in the test procedure.
5.1.5.2 Before commencing each measurement, purge the smoke tunnel with clean air to ensure that the tunnel and the specimen are free from the test aerosol.
5.1.5.3 The air velocity in the proximity of the specimen shall be (0,2 ± 0,04) rn/s unless otherwise specified in the test procedure.
5.1.5.4 Unless otherwise specified in the test procedure, the air temperature in the tunnel shall be (23 ± 5) °C and shall not vary by more than 5 K and not faster than 0,2 K/mm for all the measurements on a specimen.
5.1.5.5 Connect the specimen to its supply and monitoring equipment as described in 5,1.3, and allow it to stabilize for at least 15 mm, unless otherwise specified by the manufacturer.AS 7240.15 pdf download.
