19、 secretariat of which is held by AFNOR. 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of an identical text or by endorsement, at the latest by March 2012, and conflicting national standards shall be withdrawn at the latest by March 2012. Attention is

20、drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. NOTE Products intended for use in water supply systems must comply, when existing, with national re

21、gulations and testing arrangements that ensure fitness for contact with drinking water. On April 2006, EC Commission set up a revised mandate (M/136) asking CEN to propose harmonised product standards and support standards for test methods which could be used for assessing the fitness for contact wi

22、th drinking water. In parallel, EC Commission has launched processes for a regulation of construction products (CPR) to be substituted to CP directive (89/106/EC) and for the revision of drinking water directive (98/83/EC). If relevant, when the outputs of these processes will be known, European pro

23、duct standards will be amended by the addition of an Annex Z under Mandate M 136 which will contain formal references to the applicable requirements. Until such amendments, the current national regulations remain applicable. According to the CEN/CENELEC Internal Regulations, the national standards o
