This document (EN 13476-3:2007) 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of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by November 2007. This standard is a Part of a System Standard for plastics piping systems of particular materials for a specified application. 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. 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; — 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 (this standard); — Part 4: Assessment of conformity (CEN/TS); — Part 5: Guidance for installation (CEN/TS).1 For pipes and fittings which have conformed to the relevant national standard before May 2007, as shown by the manufacturer or by a certification body, the national standard may continue to be applied until May 2009.
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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
1 The feasibility of this project is under study.

Introduction This standard provides optional choices for impact resistance (see Annex G and Annex H) and ring flexibility (see Annex I). As appropriate, the individual countries may select between those options in their national forewords.

This part is applicable to pipes and fittings with smooth internal and profiled external surfaces, designated as Type B.
It specifies test methods and test parameters as well as requirements.
This part is applicable to: a) structured-wall pipes and fittings, which are intended to be used buried underground outside the building structure, reflected in the marking of products by “U”; b) structured-wall pipes and fittings, which are intended to be used buried underground both outside (application area code “U”) and within the building structure (application area code “D”), reflected in the marking of products by “UD”. This part 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. This part covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes, application classes, and tolerance classes and gives recommendations concerning colours. NOTE 1 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.
NOTE 2 For dimensions larger than DN 1200 OD/ID this document may be applied regarding appearance, colour, physical and mechanical characteristics as well as performance requirements. 2 Normative references

Such constructions may be Type A1, Type A2, Type B or solid plain. For definitions and specifications for Type A1 and Type A2 pipes, see EN 13476-2. NOTE Joints with elastomeric sealing rings are designed either with the sealing ring positioned on the spigot (see Figure 2), or in the socket, see Figure 3. 6 Appearance and colour The appearance and colour of the components shall conform to EN 13476-1.

7.1 General All dimensions shall be measured in accordance with EN ISO 3126. 7.2 Dimensions 7.2.1 Designation Pipes and fittings are sized either according to their outside diameter (DN/OD-series) and/or according to their inside diameter (DN/ID-series). DN/OD pipes and fittings Type B with plain spigot jointing dimensions conforming to EN 1401-1, EN 1852-1, EN 14758-1 or EN 12666-1 for PVC-U, PP, PP-MD and PE, and with larger de than the spigot, may be designated by the spigot dimension. NOTE Because of the permitted variations in geometric details, conformity to this standard does not ensure inter- changeability of pipes, fittings and other components from different manufacturers and/or different designs other than for Type A1 and solid wall components that have jointing dimensions in accordance with EN 1401-1, EN 1852-1, EN 14758-1 or EN 12666-1. EN 1852-1, EN 12666-1 and EN 14758 includes two sets of tolerances on the outside diameters of spigots. 7.2.2 Lengths of pipe The effective length of pipe l, shall not be less than that specified by the manufacturer when measured as shown in Figure 2 and/or Figure 3. 7.2.3 Diameters 7.2.3.1 Diameters of Type B pipes and spigots of pipes or fittings 7.2.3.1.1 Nominal sizes Preferred nominal sizes and minimum mean inside diameters for DN/OD and DN/ID series are specified in Table 5. Other nominal sizes, greater than DN/ID 100 and DN/OD 110 and less than DN/OD 1 200 and DN/ID 1 200, than given in Table 5, are permitted. They should preferably be selected from the Renard R40 series or traditional national dimensions. In such cases the nominal size DN/ID of pipes and fittings shall be selected in such a way that the designed minimum mean inside diameter dim,min, conforms to the requirement to maximum limit deviations on internal diameters in EN 476.
For DN/ODs and DN/IDs not specified in Table 5, the minimum inside diameter dim,min, shall be linearly interpolated between the adjacent values specified in Table 5.

7.2.5.3 Wall thickness of sockets 7.2.5.3.1 General In addition to the minimum required wall thickness of sockets and spigots, as specified below, their ring stiffness when determined in accordance with EN ISO 9969, shall conform to the following Equation (4): Sso + Ssp ≥ [SN]pipe …(4) Where
Sso I
is the ring stiffness of the socket
Ssp
is the ring stiffness of the spigot
[SN]pipe is the nominal ring stiffness of the pipe. For the test it is permitted to use cut off straight socket and spigot parts even if they do not conform to the length requirements specified in EN ISO 9969. For dimensions greater than or equal to 500 mm, the stiffness may be calculated provided reliable information regarding the E-modulus is available. 7.2.5.3.2 Wall thickness of sockets conforming to EN 1401-1, EN 1852-1, EN 14758-1 or EN 12666-1 When a socket is to conform to one of the mentioned standards, it shall comply with the wall thickness requirements of the appropriate standard. 7.2.5.3.3 Wall thickness of sockets heat formed on the pipes after extrusion When a socket is heat formed on the pipe or pipe segment after extrusion, a maximum reduction of the wall thicknesses e, e2, e4 and e5 as applicable of 15 % and e3 25 % of the manufacturers specified corresponding wall thickness of the pipe is permitted. 7.2.5.3.4 Wall thickness of other sockets with stiffness ≥≥≥≥ 4 kN/m2 For structured wall designed sockets the wall thickness e4 and e5, shall comply to the requirements given in Table 5.

c) SDR 26 series in EN 12666-1; for PVC-U, PP and PE respectively. In the case of ID series fittings the calculation shall be based on the actual outside diameter of the corresponding pipe. The jointing design including socket and spigot dimensions shall conform to 7.2.4.1 and 7.2.4.2. 7.2.5.5 Wall thickness of fabricated fittings The wall thickness of the body of fittings fabricated from pipes shall conform to the requirements of the corresponding pipe. Wall thickness reductions due to the process are permitted provided the requirements in Table 16 are met. The jointing design including socket and spigot dimensions shall conform to 7.2.4.1 and 7.2.4.2. 7.2.5.6 Wall thickness of rotational moulded fittings The minimum wall thickness in the body of rotational-moulded fittings, e4,min, shall be 1,25 times the values specified for Injection moulded fittings, rounded to the next highest 0,1 mm. If a rotational moulded fitting have a solid plain spigot and or socket, the minimum required wall-thicknesses e, e2 and e3 as applicable, shall be 1,25 times the values derived from 7.2.5. The socket and spigot dimensions shall conform to 7.2.4.2. 7.3 Types of fittings
