This European Standard specifies the characteristics of valves made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels. NOTE 1 Valves made from other material than polyethylene designed for the supply of gaseous fuels conforming to the relevant standards are permitted to be used in PE piping system according to EN 1555 provided they have relevant PE connection for butt fusion or electrofusion ends (see EN 1555 3). It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2, 3 and 5 of EN 1555, it is applicable to PE valves, their joints and to joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure, MOP, up to and including 10 bar ); b) an operating temperature of 20 °C as reference temperature; NOTE 2 For other operating temperatures, derating coefficients should be used, see EN 1555 5. c) an operating temperature between -20 °C and +40 °C. EN 1555 covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. It is applicable to bi-directional valves with spigot end or electrofusion socket intended to be fused with PE pipes conforming to EN 1555 2 without any fittings or with PE fittings conforming to EN 1555 3. This European Standard covers valves for pipes with a nominal outside diameter dn  315 mm.

This document specifies the characteristics of fusion fittings made from polyethylene (PE) as well as of mechanical fittings for piping systems in the field of the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1, 2, 4 and 5 of EN 1555, it is applicable to PE fittings, their joints and to joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure, MOP, up to and including 10 bar; b) an operating temperature of 20 °C as reference temperature. NOTE 1 For other operating temperatures, derating coefficients should be used; see EN 1555-5. EN 1555 (all parts) covers a range of maximum operating pressures and gives requirements concerning colours and additives. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. This document is applicable for fittings of the following types: c) electrofusion socket fittings; d) electrofusion saddle fittings; e) spigot end fittings (for butt fusion using heated tools and electrofusion socket fusion); f) mechanical fittings. The fittings can e.g. be in the form of couplers, equal and reduced tees, reducers, bends or caps.

This part of EN 1555 specifies the characteristics of pipes made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with Parts 1 and 3 to 5 of EN 1555, it is applicable to PE pipes, their joints and to joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure, MOP, up to and including 10 bar 1); b) an operating temperature of 20 °C as reference temperature. NOTE 1 For other operating temperatures, derating coefficients should be used, see FprEN 1555-5. EN 1555 covers a range of maximum operating pressures and gives requirements concerning colours and additives. It covers three types of pipe: - PE pipes (outside diameter dn) including any identification stripes; - PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn) as specified in Annex A, where all layers have the same MRS rating; - PE pipes (outside diameter dn) with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (‘coated pipe’) as specified in Annex B. NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. This document considers only laboratory measurements. This part of ISO 10848 specifies measurement methods to be performed in a laboratory to characterize the acoustic radiation of a building element when mechanically or acoustically excited. The measured quantities can be used to compare products, or to express a requirement, or as input data for prediction methods, such as ISO 12354-1 and -2.
