NOTE Attention is drawn to the need to take account of any relevant legislation relating to the colour coding of piping in respect of its purpose or contents for the location in which the components are intended to be used.

Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. For undated references, the latest edition of the normative document referred to applies. It presents the UK view on standards in Europe and at the international level.

Test assemblies for pressure tests shall be closed with pressuretight end-load-bearing end caps, plugs or flanges which shall be provided with connections for the entry of water and release of air.

Users of British Standards should make sure that they possess the latest amendments or editions. If printing is used, the colour of the printed information shall differ from the basic colour of the component. Components for external above-ground installations 115493 be adequately protected against UV radiation.

Such systems and components are intended to be used for industrial applications above ground. The free length l0 shall be 3dn, as defined in ISO Liquid bath or Longitudinal reversion a Temperature Immersion time: The material shall be as classified by the raw-material producer.


Other colours shall be agreed on between manufacturer and purchaser. We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover. For the design of a piping system e.

Iwo dn nominal outside diameter di inside diameter of socket at midpoint of socket length L length of socket, i. Where fittings and valves are manufactured from the same material as pipes, the material classification shall be the same as for pipes.

It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. 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: 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.

Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. Dimensions, tolerances and designation ISOPipes and fittings of plastics materials — Fittings for domestic and industrial waste pipes — Basic dimensions: Subscription pricing is determined by: In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.

If additives are used, they shall be uniformly dispersed. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. The preparation of test assemblies shall take into account tolerances related to component manufacture, field assembly and the equipment used, ambient-temperature variations during isoo and, where appropriate, sealing material 154933 associated tolerances.

For S and SDR, the respective values for the corresponding pipe shall be taken. NOTE 2 In the case of valves, 1493 those thermoplastics parts which are made from material conforming to this International Standard may be considered as reprocessable material.

ISO iiso be used as a guide. When dissimilar metallic materials are used which can be in contact with moisture, steps shall be taken to avoid galvanic corrosion. Marking shall not initiate cracks or other types of defect which adversely influence the performance of the component. Liquid bath or Temperature Immersion time: Determination methods ISO The fitting shall be connected to the corresponding pipe in accordance with Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights.

Outside the area of any injection point, no surface damage shall occur.

NOTE If test pressures defined for pipes are used for assemblies made from components of dissimilar materials e. The values of the minimum required hydrostatic strength see reference curves given in Figure B.
