30、49:2011+A1:2013 (E) 5 1 Scope This European Standard specifies the requirements for the installation of liquefied petroleum gas systems for habitation purposes in leisure accommodation vehicles and for accommodation purposes in other vehicles. It details safety and health requirements on the selecti
31、on of materials, components and appliances, on design considerations and tightness testing of installations and on the contents of the users handbook. This European Standard does not cover installations supplied from other than 3rdfamily gases (LPG), water connections or electrical power supplies to
32、 the appliance(s). Portable appliances, incorporating their own gas supply, are not considered part of the installation and are outside the scope of this standard. It does not include the installation of LPG appliances to be used for commercial purposes or for boats. Gas supply equipment and gas app
33、liances separate from and external to the body of the vehicle are also not considered by this standard. 2 Normative references !The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
