BS EN 15069:2008EN 15069:2008 (E) 6 Introduction This European Standard contains product characteristics relating to the safety of persons, animal and property and the protection of their environment. The objective of this European Standard is to achieve safe operation of connection valves by

29、specifying the requirements of performance, materials and test methods. Safety gas connection valves are used internally to connect gas appliances including movable gas appliances and externally to connect appliances such as grills, gas radiation heating, lights etc. Valves manufactured to this Euro

30、pean Standard are designed to be used with compatible hose assemblies conforming to EN 14800 and prEN 15070:2007. Attention is drawn to the need for careful quality control as given in EN ISO 9001:2000. This European Standard is based on a balance of requirements given by the major national European

31、 Gas Authorities for valves and metal hose assemblies for the connection of domestic gas appliances. It reflects the recognised practise and technology of products approved today as well as the present culture of usage by the consumer. The introduction of new technologies supported by National Gas A

32、uthorities may require the adoption of this European Standard regarding individual requirements and tests. 1 Scope These valves are suitable for connection of the fixed gas supply system to domestic appliances inside or outside a dwelling using 2ndor 3rdFamily gases and at a pressure of up to and in

33、cluding 0,5 bar. These valves are designed for the use with either movable appliances or for the connection of fixed appliances. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、pipework and whose outlet connects mechanically to the metal hose assembly and prevents any gas flow if the hose assembly is disconnected. In addition it can incorporate an overflow safety device or a thermal safety device. It also can be combined with a manually operated valve 3.1.2 safety quick co
