This European Standard shall be given the status of a national standard, either by publication of an identical text or by

20、endorsement, at the latest by October 2006, and conflicting national standards shall be withdrawn at the latest by October 2006. This document 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

21、Directive(s). It describes a test method to determine the influence(s) of factory made cementitious products on the organoleptic parameters of water intended for human consumption. Annex A, which is normative, describes additional procedures for testing factory made pipes (cement mortar lined and co
