R is the simulated leak rate C
is the criterion or threshold for indicating a leak B is the estimated bias of the system SD is the standard deviation tb is the two-sample t-test bias 4 General General principles shall be according to EN 13160-1. Tank gauge leak detection systems shall be divided into two categories of operation:  Category A: Systems providing leak detection for tanks and pipes, connected with the tank;  Category B: Systems providing leak detection for tanks only. The minimum operational performance requirements for each category are contained in Table 1. SIST EN 13160-5:2004

In addition to the performance requirements in terms of leak rates specified in Table 1 above, the tank gauge leak detection system shall be able to detect a large loss of 300 l or more in a maximum time of 30 min. Any gauge system to be used for any category of leak detection shall have water detection capability according to EN 13352. 5 Dynamic leak detection (category A) For this category, the system shall communicate with the metering system, associated with the withdrawal of product from the storage tank, in order to receive details of all volumes dispensed from the tank. At the specified leak rate according to Table 1, the system shall have a probability of detection of at least 95 % whilst a false alarm rate shall not exceed 5 %. 6 Statistical quiet period leak detection (category B (1)) For this category, the system shall be capable of detecting the 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. 7 Static tank gauge leak detection (category B (2)) For this classification, the system shall be capable, when n
