3、 marker. National foreword This standard has been prepared by CEN/TC 74. The responsible German body involved in its preparation was the Normenausschu Rohre, Rohrverbindungen und Rohrleitungen (Pipes, Pipe Joints and Pipelines Standards Committee). This standard does not preclude the use of compress

Amendments DIN 2690 and DIN 2692, May 1966 editions, and DIN 2691, November 1971 edition, have been superseded by the speci- fications of EN 1514-1. Sizes DN 4, DN 5, DN 8 and

5、DN 175 gaskets are no longer specified, size DN 60 has been included. For PN 2,3, PN 6 and PN 40 gaskets dimensions have been specified only up to size DN 600, and for PN 10, PN 16 and PN 25 gaskets, up to size 2000.

NTE om CEN/CWLEC IR Part2, 3.1.9): Where standards fall under EC Directives, it is the view of the Commission of the European Communities (OJ No G 59, 9.3.1982) that the effect of the

48、 decision of the Court of Justice in case 815/79 CremoniniNrankovich (European Court Reports 1980, p. 3583) is that compliance with A- deviations is no longer mandatory and that the free movement of products complying with such a standard should not be restricted except under the safeguard procedure

49、 provided for in the relevant Directive. A-deviations in an EFTA country are valid instead of the relevant provisions of the European Standard in that country until they have been removed.
