Scope

This CEN Technical Specification gives guidance for the assessment of conformity to be included in the manufacturer's quality plan as part of the quality system.
This Technical Specification includes:
a) requirements for materials, components and joints given in EN 13476-1, EN 13476-2 and EN 13476-3;
b) requirements for the manufacturer's quality;
NOTE 1 It is recommended that the quality system conforms to EN ISO 9001:2000 [1].
c) definitions and procedures to be applied if third party certification is involved.
NOTE 2 If third party certification is involved, it is recommended that the certification body is accredited to EN 45011 [2] or EN 45012 [3], as applicable.
This standard is applicable to:
d) structured-wall pipes and fittings, which are intended to be used buried in ground outside the building structure only; reflected in the marking of products by "U";
e) structured-wall pipes and fittings, which are intended to be used buried in ground both outside (application area code "U") and within the building structure (application area code "D"); reflected in the marking of products by "UD".
In conjunction with EN 13476-2 and EN 13476-3 it is applicable to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints.
