This document specifies the general aspects of polyethylene (PE) compounds for the manufacture of 
pressure pipes and fittings (mains and service pipes) for buried or above ground applications, intended 
for the conveyance of:
— water for human consumption;
— raw water prior to treatment;
— drainage and sewerage under pressure;
— vacuum sewer systems;
— water for other purposes.
This document also specifies the test parameters and requirements for the test methods referred to in 
this document.
In conjunction with other parts of the ISO 4427 series, this document is applicable to PE pipes and 
fittings, their joints and to joints with components made of PE and other materials, intended to be used 
under the following conditions:
a) a maximum allowable operating pressure (PFA) up to and including 25 bar ;
b) an operating temperature of 20 °C as the reference temperature.
NOTE 1 For other operating temperatures, guidance is given in Annex A.
The ISO 4427 series covers a range of maximum allowable operating pressures and gives requirements 
concerning colours.
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 installation practices or codes.
