DIN EN 13160-4:2016-12

This standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits based on the detection of the presence of liquid and/or vapour in interstitial spaces, leakage containments or monitoring wells. The kits are usually composed by: - sensing device(s); - evaluation device; - alarm device. This standard differs from DIN EN 13160-4:2003-09 as follows: a) requirements from Part 1 have been adopted in this part of DIN EN 13160; b) requirements, testing and specifications for marking have been restructured; c) a new test procedure for vapour sensors and the reusability of vapour sensors has been included; d) test liquids have been revised. This standard has been prepared under mandate M/131 "Piping, tanks and accessories not in contact with water intended for human consumption" under Regulation (EU) No. 305/2011 of the European Parliament and of the Council of 9 March 2011 laying down harmonized conditions for the marketing of construction products. The standard has been prepared by Technical Committee CEN/TC 393/WG 2 "Leak detecting devices for tanks and pipes" (secretariat: DIN, Germany). The German committee involved in the preparation of the standard was Working Committee NA 104-02-03 AA "Leckanzeigegeräte" ("Leak detection devices") at DIN Standards Committee Tank Installations (NATank).
