3、 amendment A1 is indicated by .BSI, as a member of CEN, is obliged to publish EN 16436 as a British Standard. However, attention is drawn to the fact that the UK committee voted against its approval as a European standard. Clause 8.2 states that the permeability test uses propane (at least 98 % prop
4、ane) as the medium. However, commercial propane in the UK may contain up to 100% propene. It should therefore be noted that propene is more aggressive to non-metallic compounds than propane, and may permeate through the layers of the hose more easily. The UK committee believes that this could lead t

24、(E) 4 1 Scope This European Standard specifies the characteristics and performance requirements for tubing and hoses made of either rubber or plastics for use with commercial propane and commercial butane and mixtures thereof, in the vapour phase, for connection of appliances, from: pressurized gas
25、container to a regulating device, pressurized gas container to an appliance, regulating device to an appliance, and regulating device to installation pipework, in environments of a temperature range from 30 C to +70 C. Working pressures are from 0 bar to 30 bar. Three classes are defined in Table 1
26、according to the maximum working pressures and minimum ambient temperatures. This European Standard only covers the tubing or hose part of assemblies. The assemblies themselves will be covered by EN 16436-2. This European Standard does not apply to hoses for: welding purposes (see EN ISO 3821, EN 13
27、27); propulsion purposes; LPG transfer purposes (see EN 1762). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
