EN 1451-1:2017 (E) 4 European foreword This document (EN 1451-1:2017) 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of an identical text or by endorsement, at the latest by May 2018, and conflicting national standards shall be withdrawn at the latest by May 2018. 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 1451-1:1998. EN 1451, Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure - Polypropylene (PP) consists of the following parts: — Part 1: Specifications for pipes, fittings and the system — Part 2: Guidance for the assessment of conformity (CEN/TS) The main changes with respect to the previous edition are: — updating in accordance with the new template; — updating of normative references; — thermal stability (OIT) requirement is made valid in general; — two new dimensions for nominal size and outside diameter have been added, 250 mm and 315 mm; — alignment of the impact resistance requirements for BD applications with the UD applications in
EN 1852-1; — utilization of non-virgin PP materials are described in the new Annex A; — Annex B has been deleted and the relevant text has been moved to the main standard; — new Annex B “Product
standards” has been added. System standards are based on the results of the work 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. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1451-1:2018



EN 1451-1:2017 (E) 5 1 Scope This part of EN 1451 specifies the requirements for solid-wall polypropylene (PP) pipes, fittings and the system intended for: — soil and waste discharge applications (low and high temperature) inside buildings (application area code “B”); — soil and waste discharge applications (low and high temperature) for both inside buildings and buried in the ground within the building structure (application area code “BD”). The intended use is reflected in the marking of products by “B” or “BD.
NOTE 1 For use buried in the ground within the building structure are intended only those components marked with “BD”, with dimensions equal to or greater than 75 mm and nominal ring stiffness of at least SN4. This part of EN 1451 is also applicable to PP pipes and fittings and the system intended for the following purposes: — ventilating part of the pipework in association with discharge applications; — rainwater pipework within the building structure. It also specifies the test parameters for the test methods referred to in this standard. This European Standard covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations 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 any relevant national regulations and installation practices or codes, e.g. CEN/TR 13801 [1]. NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex B can be used with pipes and fittings conforming to this European Standard, provided they conform to the requirements for joint dimensions given in Clause 6 and to the requirements of Table 18. This standard applies to pipes and fittings, marked with “B”, which are intended to be used inside buildings and outside buildings fixed onto the wall. It applies to pipes and fittings, marked with “BD”, which are intended to be used for both inside buildings and buried in the ground within the building structure. This standard is applicable to PP pipes and fittings of the following types: — plain-ended, — with integral elastomeric ring seal socket, — for butt fusion joints, whereby the fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings. NOTE 4 EN 476 [2] specifies the general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to this standard fully meet these requirements. NOTE 5 For information about the chemical resistance of PP, guidance is given in ISO/TR 10358 [3] and for rubber materials in ISO/TR 7620[4]. SIST EN 1451-1:2018
