scope:

This Standard specifies the following classes of buried polyethylene pipes used for the supply of town gas and liquefied petroleum gas (hereafter, referred to as "pipes").

-Single layer pipes (including the polyethylene pipes with identifying stripe)

-Polyethylene pipes with co-extruded two layers or three layers specified in Annex A The material of each layer to be used shall have that of the same MRS.

-Covered pipes specified in Annex B that are polyethylene pipes covered with peelable thermoplastic material on the outside surface

NOTE 1 Annex C gives guidance on a calculation and design scheme on which the maximum operating pressure of polyethylene pipes specified in this Standard is based.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence is as follows.

ISO 4437: 2007 Buried polyethylene (PE) pipes for the supply of gaseous fuels-Metric series-Specifications (MOD)
