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of an identical text or by endorsement, at the latest by November 2007, and conflicting national standards shall be withdrawn at the latest by November 2007.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 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. 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)

The required legibility of marking is coded as follows: a) durable in use; b) legible at least until the system is installed; c) marking on the packaging is legible at least until the component is installed. NOTE The manufacturer is not responsible for marking becoming illegible due to actions during installation and use such as painting, scratching, covering of the components or by use of e.g. detergents on the components, unless agreed with, or specified by the manufacturer. 10.2 Marking process Marking shall be carried out so it does not initiate cracks or other types of defects which are likely to prevent conformity to this standard. 10.3 Size The size of the marking shall be such that the marking is legible without magnification.

Characteristics of PVC-U, PP and PE pipes and fittings A.1 General EN 476 [7] specifies general requirements for components used in discharge pipes, drains and sewers for gravity systems. Pipes and fittings conforming to this standard meet these requirements.
A.2 Material characteristics The materials of pipes and fittings conforming to this standard have the characteristics given in Table A 1. Table A.1 Characteristic PVC-U PP PE Unit Modulus of elasticity, E (1min) ≥ 3 200 ≥ 1 250 ≥ 800 MPa Average density ≈ 1400 ≈ 900 ≈ 940 kg/m3 Average coefficient of linear thermal expansion ≈ 8 × 10-5 ≈ 14 × 10-5 ≈ 17 × 10-5 K-1 Thermal conductivity ≈ 0,16 ≈ 0,2 ≈ (0,36 to 0,50) WK-1m-1 Specific heat capacity ≈ (850 to 2 000) ≈ 2000 ≈ (2 300 to 2 900) Jkg-1K-1 Surface resistance > 1012 > 1012 > 1013

0,4 0,42 0,45 (-) NOTE Values are dependent on the material used. Therefore, it is recommended to contact the manufacturer, or see the manufacturer's documentation, for the relevant values in each individual case.
If information regarding the tensile strength and/or elongation of break of a material is needed, they can be determined in accordance with EN ISO 6259-1 [24] combined with EN ISO 6259-2 [25] or EN ISO 6259-3 [26] as applicable. A.3 Chemical resistance Piping systems conforming to this standard are resistant to corrosion by water with a wide range of pH values such as domestic wastewater, rainwater, surface water and ground water. If piping systems conforming to this standard are to be used for chemically contaminated wastewaters, such as industrial discharges, chemical and temperature resistance have to be taken into account. For information about the chemical resistance of PVC, PP and PE materials, guidance is given in ISO/TR 10358 [22] and for rubber materials in ISO/TR 7620 [27].
EN 13476-1:2007 (E) 18 A.4 Abrasion resistance Pipes and fittings conforming to this standard are resistant to abrasion.
The abrasion can be determined from the test method given in EN 295-3:1991 [28]. A.5 Hydraulic roughness The internal surfaces of pipes and fittings conforming to this standard are hydraulically smooth. The design of joints and fittings ensure good hydraulic performances. For further information about hydraulic capacity of pipes and fittings conforming to this standard refer to the manufacturer’s information.

Structural design B.1 General In general creating a structural design of a thermo-plastics pipeline construction by applying analytical or numerical methods is not needed. Any calculated prediction of the pipe behaviour and reality is strongly dependent on the conditions used for the calculation being the same as used for the installation. Therefore, it is important that effort is put into controlling the input values by extensive soil surveys and monitoring the installation. In many cases, practical and/or reference information is available and results in a sound prediction of the pipe performance. B.2 Structural design based on practical experience The following method described below fulfils 4.2 of EN 1610:1997 [29]. Designers first need to establish permitted deflections, average and maximum. (National requirements, product standards, this standard etc. offer guidance.) An intensive study of the deflection history of pipes installed under different conditions up to 25 years ago has resulted in experience as presented in the design graph shown in Figure B.1. For the deflection mentioned in the design graph, the strain will be far below the design limit.
