28、 connection of appliances, from: pressurized gas 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
29、 to 30 bar. Three classes are defined in Table 1 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 ho
30、ses for: welding purposes (see EN ISO 3821, EN 1327); 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.
