The manufacture of all asbestos products is covered by the requirements of The Control of Asbestos at
10、Work Regulations 1987, introduced on 1 March 1988. These set out comprehensive provisions covering work activities involving exposure to asbestos. Advice on how to comply with these regulations can be obtained from the manufacturers of the material, from the Asbestos Information Centre Ltd., Derby R

22、s of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A ve

A distinction
25、has been made between product appraisal (type tests) and routine quality control requirements (acceptance tests). Attention is drawn to the need for observance of EU and/or EFTA Directives transposed into national legal requirements restricting the use of certain materials and to the related marking
26、 and labelling requirements. The performance of a sewage network constructed with these products depends not only on the properties of the product as required by this standard but also on the design and construction of the network as a whole in relation to the environment and conditions of use. This
27、 standard will be updated with the standard EN 476 General requirements for components used in discharge pipes, drains and sewers for gravity systems established by TC 165 WG 1 and the other functional standards as soon as these are available. This European Standard shall be given the status of a na
28、tional standard, either by publication of an identical text or by endorsement, at the latest by February 1997, and conflicting national standards shall be withdrawn at the latest by February 1997. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followin
29、g countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

It is applicable only to the more
33、 commonly used fittings i.e. angled branches or tees and bends. It defines general composition, classification, geometrical, mechanical and physical characteristics, acceptance tests, type tests and quality control. For pressurized sewers, fibre-cement pipes and joints in accordance with EN 512 will
34、 be used with additional consideration relevant to sewerage transport. NOTE 1. EN 588-2 specifies requirements for fibre-cement manholes and inspection chambers. NOTE 2. Occasional momentary overpressures of no more than 100 kPa are acceptable. 2 Normative references This European Standard incorpora

40、d number approximately equal to the manufacturing dimension in millimetres of the internal diameter. 3.2 acceptance test Test to establish whether a batch of products conforms to a specification of the standard. The tests are performed on samples drawn either from continuous production or from a con
41、signment (ISO 390 : 1993). NOTE. Tests methods, specifications and limit values are specified in this standard. Sampling levels and acceptance criteria are specified in ISO 390. 3.3 type test Test for approval of a new product and/or a fundamental change in formulation or method of manufacture, or b
42、oth. The test is performed on the as delivered product. The type test is not to be taken as evidence of the conformity to specification of products subsequently produced in quantity (ISO 390 : 1993). 3.4 acceptable quality level (AQL) When a continuous series of batches is considered, the quality le
43、vel which for the purposes of sampling inspection is the limit of a satisfactory process average (ISO 2859-1 : 1989). NOTE. A sampling scheme with an AQL of 4 % means that batches containing up to 4 % defective items have a high probability of acceptance. 3.5 pipe barrel Cylindrical part of the pipe
44、 with a uniform cross-section excluding socket and spigot. 4 Pipes 4.1 General composition Fibre-cement pipes shall consist essentially of cement or a calcium silicate formed by chemical reaction of a siliceous and a calcareous material, reinforced by fibres. The cement shall comply with relevant na
45、tional standards of CEN members and/or ENV 197-1. NOTE. Other components which are compatible with the composite and have no negative influence on the performance in use of the product, can be added. Two types of fibre-reinforced cement products (pipes, joints and fittings) are included in this stan
46、dard: type AT (Asbestos Technology) for products the formulation of which contains chrysotile asbestos; type NT (Non-asbestos Technology) for products the formulation of which does not contain asbestos. For products of type AT and NT all the requirements of this standard shall be fulfilled.Page 4 EN
47、 588-1 : 1996 BSI 1997 Figure 1. Pipe ends 4.2 Classification The pipes shall be classified in accordance with their minimum crushing strength in three classes based on load per unit internal area: 60 kN/m 2 , 90 kN/m 2 , 120 kN/m 2 . The load per unit area is the breaking load in kilonewtons per me
48、tre length of pipe divided by the nominal diameter of the pipe in metres (1/1000 of the nominal diameter values). 4.3 Pipe ends Pipes shall either have plain ends or with one end plain and the other end with a fixed socket. Plain ends may be machined or un-machined (see figure 1). 4.4 General appear
49、ance and finish The pipes shall be straight, uniform and regular. The shape of the finished end shall be fixed by the manufacturer to suit the type of joint used. The end faces shall be free from breakout and machining burrs. The parts of the pipe where the rubber jointing rings are located shall be free from irregularities which could affect the watertightness of the joint. NOTE. If necessary, the pipes can be impregnated and/or coated internally and/or externally to meet special working conditions as agreed between manufacture
