42、liquid beyond a fixed point in a connecting line 4 Classes of leak detection systems For the purpose of this standard the following classes apply in order of protection for the level of safety or environmental protection required: Class I: Systems of this class will detect a leak above as well as be

43、low the liquid level in a double-skin system. They are inherently safe and will detect a leak before any liquid can enter the environment (i.e. pressure or vacuum systems). Class II: Systems of this class will detect a leak above as well as below the liquid level in a double-skin system with the pos

44、sibility of the leak detection liquid leaking into the environment (i.e. liquid monitoring system). Class III: Systems of this class will detect a leak below the liquid level in a tank or in a pipework system. These systems are based on liquid and/or vapour sensors located in leakage containment or

45、interstitial space. A possibility exists of product entering the environment. Class IV: Systems of this class will detect, to specific levels of probability, specified rates of change of tank contents (i.e. leakages into or out of the tank). A strong possibility exists that product will enter the en

46、vironment in the event of a leak. Class IV A: Dynamic leak detection systems will by reconciliation also indicate leaks in the connected pipework. Class IV B: Static tank gauge leak detection systems or statistical quiet period leak detection systems will only indicate leaks in a tank. Class IV C: P

47、ressure line leak detection system which will detect a leak in pressurized pipework, only when no product is being dispensed. Class V: Systems of this class may detect liquid loss in tanks or pipework below the liquid level. Product will enter the environment before the leak is detected (i.e. sensor

48、s of class III in monitoring wells). For examples for the different classes see Annex A. 5 Requirements 5.1 General Leak detection systems shall trigger the alarm in the event of a leak or in the event of malfunctions of the leak detection system. All leak detection systems shall indicate every leak

49、 by a visual and audible alarm. In the event of a power interruption, the leak detection system shall be designed to resume normal operation on the restoration of the power supply.
