The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.
ISO shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given by the European Commission and the European Free Trade Association and supports essential requirements of EU Directives. At the date of publication of this International Standard, the following standards had been published for piping systems, used for industrial applications, made from other types of plastic: This International Standard is applicable to ABS, PVC-U or PVC-C pipes, fittings, valves and ancillary equipment, to their joints and to joints with components made of other plastics and non-plastics materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as of solid matter in fluids for industrial applications such as: NOTE 1 Where relevant, national regulations for specific applications e.
Relevant regulations in respect of fire behaviour and explosion risk are applicable if applications are envisaged for inflammable media.
The components have to withstand the mechanical, thermal and chemical demands to be expected and have to be resistant to the fluids to be conveyed. Those characteristics and requirements which are dependent on the material 15439 given for each material in the relevant annex see Table 1. Table 1 — Material-specific annexes Material Annex Acrylonitrile-butadiene-styrene ABS A Unplasticized poly vinyl chloride PVC-U B Chlorinated poly vinyl chloride PVC-C Isso NOTE 2 Components conforming to any of the product standards listed in the bibliography or to national standards, as applicable, may be used with components conforming to this International Standard provided they conform to the requirements is joint dimensions and to the other relevant requirements of this standard.
For dated references, subsequent amendments to, or revisions of, any of these is do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
For undated references, the latest edition of the normative 1543 referred to applies.

If additives are used, they shall be uniformly dispersed. Additives shall not be used, separately or together, in quantities sufficient to impair the fabrication or solvent- cementing characteristics of the components or to impair the chemical, physical or mechanical characteristics as specified in this International Standard.
The test shall be isso out using test pieces of pipe series S u 12,5. The material shall be as classified by the raw-material producer. Where fittings and valves are manufactured from the same material as pipes, the material classification shall be the same as for pipes. For the classification of a material intended only for the manufacture of fittings and valves, an injection-moulded ieo extruded test piece in the form of a pipe shall be used see Figure 1 and the test pressure applied in accordance with ISO The free length l0 shall 1549 3dn, as defined in ISO Reprocessable material obtained from external sources and recyclable material shall not be used.
Alternative standards may be used in cases where suitable International Standards do not exist. In all cases, the fitness for purpose of the components shall be demonstrated. When dissimilar metallic materials are used which can be in contact with moisture, steps shall be taken to avoid galvanic corrosion.
The components shall not contain visible impurities. Each end of a component shall be square to its axis and shall be deburred. NOTE Attention is drawn to the need to take account of any relevant legislation relating to the colour iiso of piping in respect of its purpose or contents for the location in which the components are intended to be used. Components iiso external above-ground installations shall be adequately protected against UV radiation. The measurements shall not be made less than 24 h after manufacture.
The illustrations given in this International Isoo are schematic sketches only, to indicate the relevant dimensions. Isk do not necessarily represent manufactured components. The dimensions given shall be followed. Dimensions not given shall be as specified by the manufacturer.

The out-of-roundness shall be measured at the point of manufacture. NOTE The laying lengths are intended to assist in the design of moulds and are not intended to be used for quality control purposes. ISO may be used as a guide. Where a thread is used as a fastening thread for jointing an assembly e.
For S and SDR, the respective values for the corresponding pipe shall be taken. The adhesive s shall have no detrimental effect on the properties of the components and shall izo cause the test assembly to fail to conform to the requirements given in the applicable annex to this International Standard. NOTE If test pressures defined for pipes are used for assemblies made from components of dissimilar materials e. These strains inevitably cause leakage. Therefore, in this International Standard, the time-related strain behaviour of the assemblies is taken into account and test pressures derived from the isochronous stress-strain diagram are used.
The preparation of test assemblies shall take into account tolerances related to component manufacture, field assembly and the equipment used, ambient-temperature variations during installation and, where appropriate, sealing material and associated tolerances. Test assemblies for pressure tests shall be closed with pressuretight end-load-bearing end caps, plugs or flanges which 1543 be provided with connections for the entry of water and release of air.
The classification of fittings shall be based on that of the corresponding pipe together with the pipe series S or the standard dimension ratio SDR or the 51493 pressure PN, as applicable.
For the design of a piping system e.
For external above-ground installation, additional requirements depending on the climate shall be agreed on between manufacturer and purchaser. NOTE The manufacturer is not responsible for the marking on a component becoming illegible due to actions caused during installation and use such as painting, scratching or covering over, or the use of detergents, etc.
Marking shall not initiate cracks or other types of defect which adversely influence the performance of the component. If printing is used, the colour of the printed information shall differ from the basic colour of the component. The size of the marking shall be such that the marking is legible without magnification.
