scope:

This part of the standard specifies the characteristics of pipes made from polyethylene (PE) intended for the conveyance of water for human consumption including raw water prior to treatment. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with other parts of EN 12201 (see Foreword) 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 operation pressure, MOP, up to and including 25 bar. b) an operation temperature of 20°C as a reference temperature. NOTE 1 For applications operating at constant temperatures greater than 20°C and up to 40°C, see annex A of EN 12201-1. This European Standard 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 guidance or regulations and installation practices or codes. NOTE 3 Assessment of the resistance to slow crack growth of the PE pipe compound used for the manufacture of products to this specification is required in accordance with Table 2 of EN 12201-1.
