DIN EN 13160-3:2016-12

This standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits based on the drop of the liquid level in the leak detection kits header tank. Leak detection kits are intended to be used with double skin, underground or above ground, non-pressurized, tanks designed for water polluting liquids. The kits are usually composed of: - sensing device; - evaluation device; - alarm device. The standard differs from the previous edition DIN EN 13160-3:2003-09 as follows: a) requirements and test methods for the leak detection liquids have been revised; b) the EU Construction Products Regulation No 305/2011 has been taken into account; c) the technical requirements for the system provided, consisting of sensing device, evaluation device and alarm device, have been restructured; d) environmental aspects have been included; e) requirements from Part 1 have been adopted in this part of DIN EN 13160; f) requirements for software have been included; g) references to Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), establishing a European Chemicals Agency, and to GHS, Globally Harmonized System of Classification and Labelling of Chemicals, have been included; h) temperature types are now used; i) the crevice test pieces and test method have been changed. 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).
