European Standard EN 12255-13 : 2002 has the status of a DIN Standard.
A comma is used as the decimal marker.
National forewordThis standard has been prepared by CEN/TC 165 ‘Waste water engineering’ (Secretariat: Germany).The responsible German body involved in its preparation was the Normenausschuss Wasserwesen (WaterPractice Standards Committee), Technical Committee Abwasserbehandlungsanlagen.This European Standard is part of a series of standards dealing with wastewater treatment plants within thescope of the EC Directive on the approximation of the laws, regulations and administrative provisions of theMember States relating to construction products.It should be noted that not all of the DIN Standards dealing with wastewater treatment plants need yet bewithdrawn. This is in keeping with resolution 152/98 taken by CEN/BT, which states that where ‘packages’of EN Standards are concerned, it shall be permitted for the relevant national standards (DIN 19569 series)to remain valid for longer periods than usual, until the EN ‘package’ has been published in its entirety.In the case at hand, all of the relevant EN Standards have not yet been published, and CEN/TC has thereforedecided to extend the period of validity for relevant national standards until the end of 2002.It should be noted that the scope of the EN 12255 series is not identical with that of the DIN 19569 series.
