EN 13476-1:2018 (E) 4 European foreword This document (EN 13476-1:2018) 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of an identical text or by endorsement, at the latest by October 2018, and conflicting national standards shall be withdrawn at the latest by October 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN not be held responsible for identifying any or all such patent rights. This document supersedes EN 13476-1:2007. The main changes with respect to the previous edition are listed below: a) updating of references in Clause 2, Table 2 and Bibliography; b) deletion of Note 3 (Scope); c) definition fabricated fitting changed (3.1.1.3); d) clarification requirements sealing ring (4.4); e) extension of nominal sizes range (Table 1, Table 2); f) substitute “DURABILITY” Table 2; g) new reference for hydraulic roughness (A.5); h) text updated and new reference (Annex B); i) adhesives PVC-U added (4.6); j) saddle branches deleted (8.1); k) updated with new CEN template (entire document). This standard is a part of a System Standard for plastics piping systems of particular materials for specified applications. There are a number of such System Standards. 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. SIST EN 13476-1:2018



EN 13476-1:2018 (E) 5 EN 13476 consists of the following parts under the general title “Plastics piping systems for non-pressure underground drainage and sewerage — Structured-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE)”: — Part 1: General requirements and performance characteristics (this standard); — Part 2: Specifications for pipes and fittings with smooth internal and external surface and the system, Type A; — Part 3: Specifications for pipes and fittings with smooth internal and profiled external surface and the system, Type B; — Part 4: Assessment of conformity. National standards specifically for pipes and fittings for the transport of surface water are not considered to be conflicting with this standard and may thus be allowed to coexist. According to the CEN/CENELEC Internal Regulations, the national standards organizations 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.

Table 1 — Nominal sizes Nominal sizes: DN/ID (in mm) 100, 125, 150, 200, 225, 250, 300, 400, 500, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400, 2500, 2600, 2800, 3000 Nominal sizes: DN/OD (in mm) 110, 125, 160, 200, 250, 315, 400, 500, 630, 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400, 2500, 2600, 2800, 3000 NOTE For dimensions larger than DN 3000 OD/ID this document may be applied regarding appearance, colour, physical and mechanical characteristics as well as performance requirements. Other sizes are permitted when following the conditions given in EN 13476-2 or EN 13476-3. 8 Types of fittings 8.1 General This standard is applicable for the following types of fittings. Figures 1 to 6 give examples for typical designs. Other designs of fittings including all socket and all spigot, are permitted. a) Bends un-swept and swept angle (see Figure 1 and Figure 2). NOTE Preferred nominal angles, , are the following: 15°, 22,5°, 30°, 45° and between 87,5° and 90°. SIST EN 13476-1:2018

Figure 5 — Example of a swept entry and a straight branch d) Plugs (see Figure 6). The insert length, L1, shall be sufficient to ensure engagement of the sealing ring of at least 10 mm: i) when measured from the effective sealing point to the end of the cylindrical part of the spigot when the sealing ring is positioned in the socket, or ii) when measured from the effective sealing point to the mouth of the cylindrical part of the socket when the sealing ring is positioned on the spigot.

EN 13476-1:2018 (E) 15 8.2 Design length of fittings The design length(s) (Z-lengths) of the fittings (see Figure 1 to Figure 6) shall be declared by the manufacturer. NOTE The design lengths (Z-lengths) are intended to assist with the design of moulds and are not intended to be used for quality control purposes, ISO 265-1 [2] can be used as a guideline. 9 System performance related test methods and characteristics The performance of the installed piping system depends on the quality of the system components and installation conditions and workmanship. The performance requirements of the system components and their relation to the tested characteristics specified in EN 13476-2 or EN 13476-3, as applicable, are explained in Table 2. Annex B gives guidelines for structural design. SIST EN 13476-1:2018
