This document gives requirements and the corresponding test/assessment methods applicable to leak detector based on the measurement of pressure change. Leak detectors are intended to be used with double skin, underground or above ground, pressurized or non-pressurized, tanks or pipe designed for water polluting liquids/fluids. The leak detectors are usually composed of: - measuring device; - evaluation device; - alarm device; - pressure generator; - pressure relief device; - liquid stop device; - condensate trap.

This document specifies requirements and the corresponding test/assessment methods applicable to leak detection linings and leak detection jackets. Leak detection linings and leak detection jackets are intended to be used, in conjunction with leak detection kits, to create an interstitial space or leakage containment in single skin underground or above ground, non-pressurized tanks designed for water polluting liquids. For leak detection kits, see EN 13160 2, EN 13160 3 and EN 13160 4.

This document specifies the methods of examining the knowledge and skill set of the fitter required to carry out on-site joint casing connections on thermally insulated single and twin pipe systems for directly buried hot and cold water networks according to .The application of these specified methods specifications ensures that the examination is carried out according to a standardised examining procedure.This document covers the following processes: - preparatory works for joint casing assembly; - assembling and testing the elements for surveillance systems; For special surveillance systems it can be important to have additional training.preparing work for joint casing system installation; - assembling sealable joint casing system; - verifying joint tightness (leakage testing); - thermally insulating the joint casing ( PUR foaming or half-shells); - sealing fill & vent openings (weldable or sealable plugs); - assessing overall installation quality of the completed joint connection (non-destructive).

1.1 General This document specifies the requirements for portable locating leak detectors and fixed gas detectors for refrigerants. Locating detectors used in factories for manufacturing processes are not included in the Scope of this document. 1.2 Product application This document applies to different applications and environments such as plant and machine rooms, production rooms, cold rooms, supermarkets, occupied spaces like offices and hotels. 1.3 Product performance This document specifies minimum requirements for sensitivity, operating range, response time, environmental conditions and cross sensitivity from interference gases. 1.4 Product installation This document gives guidance of suitable technology, location of detection points, interconnection with secondary equipment (e.g. initiation of mechanical ventilation, personnel warning, and equipment shutdown). 1.5 Service and maintenance This document gives guidance for service and maintenance: Sensors and mechanical equipment have a limited operating life and require regular performance verification to ensure conformity.
