BS EN 1916:2002 together with BS 5911-1:2002 supersedes BS 5911-100:1988 and BS 5911-120:1989, which are also withdrawn. Therefore,
4、BS 5911-1:2002 is for use in conjunction with BS EN 1916:2002 and both came into effect simultaneously. In order not to create barriers to European trade, products under the scope of this British Standard should be specified as conforming to “BS EN 1916:2002 and BS 5911-1:2002 or equivalent”. The fo

36、tariat of which is held by DIN.It is a companion standard to EN 1917 “Concrete manholes and inspection chambers, unreinforced, steel fibre andreinforced”.This European Standard shall be given the status of a national standard, either by publication of an identical text or byendorsement, at the lates
37、t by April 2003, and conflicting national standards shall be withdrawn at the latest by October2004.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship
38、with EU Directive(s), see informative annex ZA, which is an integral part of this document.This European Standard includes eleven normative annexes and one informative annex. Annexes A, B, C, D, E, F,G, H, I, J and K are normative, annex ZA is informative.When the text of this European Standard was
39、approved, complete agreement could not be achieved for allrequirements in the existing national specifications of CEN members and so it includes only those requirementsand associated test methods for which a consensus could be reached. Consensus was achieved on therequirements for quality control.NO
40、TE For the time being, for specification purposes, complementary (i.e. non-conflicting) requirements and associated testmethods outside the scope of this European Standard (see Table 1) will be needed at national level. In order not to create anybarrier to trade, any call for conformity to complemen
