A similar fitting shall be provided having a drain cock, orsuitable syphon system, capable of emptying the vessel at a rate of 5 l/min.Suitable quantities of each liquid for qualification (or suitable test liquids).A calibrated metering pump (with a reservoir of minimum 6 l capacity) capable of delivering liquid into the testvessel, at the rates specified in 11.1.2 within an accuracy of 2 %.An environmental chamber the temperature of which can be varied over the range from - 25 C to + 70 C with anaccuracy of 2 K.For the test in a temperature range from – 40 °C to + 40 °C an environmental chamber the temperature of whichcan be varied over the range from – 50 °C to + 40 °C with an accuracy of 2 K.A stop clock having a time indication in steps of 1 s to a minimum total of 24 h, with an accuracy of 2 s.11.1.4Test method11.1.4.1PreparationThe sensor under test shall be fixed in its normal orientation ensuring contact with the floor of the test vessel but awayfrom any ports for the entry or extraction of liquid. The manufacturer's fittings should be used wherever possible. Thetest vessel and metering pump reservoir shall be mounted inside the environmental chamber. The sensor under testshall be connected to the leak indicating device under test which shall be mounted outside the environmentalchamber in ambient laboratory conditions.Prior to the series of tests for each liquid for which the sensor system shall be qualified, the metering pump reservoirshall be charged with the appropriate liquid or test liquid and the test vessel filled with water to the appropriate level.Power shall be applied to the sensor system which shall be then initialised by means specified in the manufacturer'soperating instructions such that the system is fully operational.11.1.4.2StabilisationPrior to each test to be conducted, and with the sensor system fully operational, the environment chamber shall bepreset to the required test temperature, and shall be allowed to stabilize for 30 min after the internal temperaturereaches the prescribed test temperature ± 2 K.SIST EN 13160-4:2003
