3、s the UK implementation of EN 1917:2002, incorporating corrigenda December 2003, December 2006 and April 2008. BS EN 1917:2002 together with BS 5911-3:2002 supersedes BS 5911-200:1994, which is withdrawn. BS EN 1917:2002 together with BS 5911-4:2002 supersedes BS 5911-2:1982, which is also withdrawn

4、. Therefore, BS 5911-3:2002 and BS 5911-4:2002 are for use in conjunction with BS EN 1917:2002 for manholes and inspection chambers respectively and all three came into effect simultaneously. In order not to create barriers to European trade, products under the scope of this British Standard should

5、be specified as conforming to BS EN 1917:2002 and BS 5911-3:2002 (or BS 5911-4:2002) or equivalent. The foreword of EN 1917:2002 explains why, and under what circumstances, complementary requirements and associated test methods outside the scope of that standard will be needed at national level.The

38、his European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest byOctober 2004.This document has been prepared under a mandate given t

39、o CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.This European Standard includes ten normative annexes and one in

40、formative annex. Annexes A, B, C, D, E, F, G,H, I and J are normative, annex ZA is informative.When the text of this European Standard was approved, complete agreement could not be achieved for allrequirements in the existing national specifications of CEN members and so it includes only those requi

41、rementsand associated test methods for which a consensus could be reached. Consensus was achieved on therequirements for quality control.NOTE For the time being, for specification purposes, complementary (i.e. non-conflicting) requirements and associated testmethods outside the scope of this Europea

42、n Standard (see Table 1) will be needed at national level. In order not to create anybarrier to trade, any call for conformity to complementary requirements should always be qualified by incorporating the words orequivalent after the reference to them.According to the CEN/CENELEC Internal Regulation
