17、r engineering, the Secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by January 2001, and conflicting national standards shall be withdrawn at the latest by January
18、 2001. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follo
19、wing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This European Standard was prepared by wor
20、king group 5 of CEN Technical Committee TC 165 on Waste water technology. A distinction has been made between initial control of products (type tests) and internal quality control requirements (acceptance tests). The performance of a water discharge system network constructed with these products dep
21、ends 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 standard is in accordance with EN 476:1996, General requirements for components used in discharge p
22、ipes, drains and sewers for gravity systems, established by TC 165 WG 1 and will be in accordance with other functional standards as soon as these are available. Annexes A and B of this European Standard are normative; Annexes C, D and E are informative.Page 4 EN 12763:2000 BSI 11-2000 1 Scope This
23、European Standard applies to fibre-cement pipes, joints and fittings used for sewerage and rainwater discharge systems for buildings where pressure tight joints are required. It defines general composition, classification, geometrical, mechanical and physical characteristics and quality control. 2 N

32、hich is a convenient round 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 test is performed on samples drawn either from continuous pr
33、oduction or from a consignment ISO 390:1993 NOTE: Test method, 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 ma
34、nufacture, or both. 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
35、quality level 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.Page 6 EN 12763:2000 BSI 11-2000 4 Symbo
