European foreword
This document (EN 1555-3:2021) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2022, and conflicting national standards shall
be withdrawn at the latest by January 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1555-3:2010+A1:2012.
In comparison with the previous version, the following technical modifications have been introduced:
— PE 100-RC type materials with enhanced resistance to slow crack growth have been added.
— Annex A of EN 1555-1:2021 now discusses the performance of this type of material and gives
additional information for non-conventional installation techniques.
— Additional information for non-conventional installation techniques has been added.
— The size range has been increased to 800 mm diameter.
— Test methods have been updated.
System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics pipes,
fittings and valves for the transport of fluids”, which is a Technical Committee of the International
Organization for Standardization (ISO).
They are supported by separate standards on test methods to which references are made throughout the
System Standard.
The System Standards are consistent with general standards on functional requirements and on
recommended practice for installation.
EN 1555 consists of the following parts:
— EN 1555-1, Plastics piping systems for the supply of gaseous fuels — Polyethylene (PE) —
Part 1: General;
