This document specifies the characteristics of pipes made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels.<\/p>\n

It also specifies the test parameters for the test methods referred to in this document.<\/p>\n

In conjunction with Parts 1 and 3 to 5 of EN 1555<\/span><\/span> , 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:<\/p>\n

    \n
  1. \n

    a maximum operating pressure, MOP, up to and including 10 bar 1<\/sup><\/span><\/p>\n

    \n
    \n 1<\/sup>\n <\/div>\n

    bar = 0,1 MPa. = 10 5<\/sup> Pa; 1 MPa = 1 N\/mm 2<\/sup>.<\/p>\n<\/p><\/div>\n

    at a reference temperature of 20 \u00b0C for design purposes; <\/li>\n

  2. \n

    an operating temperature between ?20 \u00b0C and 40 \u00b0C.<\/p>\n<\/li>\n<\/ol>\n

    \n
    \n NOTE 1\n <\/div>\n

    For operating temperatures between 20 \u00b0C and 40 \u00b0C derating coefficients are defined in EN 1555?5:2021<\/span><\/span> .<\/p>\n<\/div>\n

    EN 1555<\/span><\/span> covers a range of maximum operating pressures and gives requirements concerning colours.<\/p>\n

    It covers three types of pipe:<\/p>\n

      \n
    1. \n

      PE pipes (outside diameter d<\/i> n<\/sub>) including any identification stripes;<\/p>\n<\/li>\n

    2. \n

      PE pipes with co-extruded layers on either or both the outside and\/or inside of the pipe (total outside diameter d<\/i> n<\/sub>) as specified in Annex A<\/span>, where all layers have the same MRS rating. A coextruded pipe made of a combination of PE 100 and PE 100-RC layers shall be regarded as PE 100 and marked accordingly;<\/p>\n<\/li>\n

    3. \n

      PE pipes (outside diameter d<\/i> n<\/sub>) with a peelable, contiguous thermoplastics additional layer on the outside of the pipe (\u2018coated pipe\u2019) as specified in Annex B<\/span>.<\/p>\n<\/li>\n<\/ol>\n

      \n
      \n NOTE 2\n <\/div>\n

      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.<\/p>\n<\/div>\n
