At

39、e specified leak rate according to Table 1 with a probability of at least 95 % whilst operating at a false alarm rate of 5 % or less. 8 Leak indicating device A leak indicating device shall be provided. In addition for categories A and B, the requirements of a gauge control device as defined in EN 1

Where performance in accordance with Table 1 is not achievable within the required levels of probability, the results shall be reported as inconclusive. License
