Plastics piping systems for hot and cold water installations - Polyethylene of raised temperature resistance (PE-RT) - Part 7: Guidance for the assessment of conformity (ISO/DTR 22391-7:2010)

Scope

This Technical REPORT gives guidance for the assessment of conformity to be included in the manufacturer's quality plan as part of his quality system. This Technical Specification includes: a) requirements for materials, components, joints and assemblies given in the applicable Part(s) of ISO/FDIS 22391; b) requirements for the manufacturer's quality system; NOTE 1 It is recommended that the quality system conforms to ISO 9001:2000[2]. 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[3] or EN 45012[4], as applicable. In conjunction with the other Parts of ISO/FDIS 22391 (see Foreword), this Part is applicable to Polyethylene of raised temperature resistance (PE-RT) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems), under design pressures and temperatures appropriate to the class of application (see Table 1 of ISO/FDIS 22391-1:(2008)).
