24 The piping precision leak detection test referred to in section 17 and paragraphs 23(1)(c) and 26(d) must

• (a) be capable of detecting a leak rate of at least 0.38 L/h within a 24 hour period at a line pressure of 310 kPa with a probability of detection of 0.95 or greater and a probability of false alarm of 0.05 or less, accounting for variables such as vapour pockets, thermal expansion and contraction, static head pressure, temperature differential and piping compressibility; and

• (b) be performed, using a documented and validated method, by an individual trained in the maintenance and use of the test equipment.
