European Standard EN 1514-1 : 1997 has the status of a DIN Standard. A comma is used as the decimal
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
4、ed asbestos fibre gaskets. It should be noted, however, that the use of asbestos-free gaskets only is permitted in Germany. Amendments DIN 2690 and DIN 2692, May 1966 editions, and DIN 2691, November 1971 edition, have been superseded by the speci- fications of EN 1514-1.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. Previous editions DIN 2690: 1927-01, 1949-12, 1966-05; 1949-12, 1966-05. DIN 2691:

43、gasket type, material and thickness should be made in consultation with the gasket supplier. The selection of gasket material, type and thickness should take into account the fluid, the operating conditions, the properties of the gasket material, the type and surface nish of the flange facing and th
44、e flange bolt loading. The following information should be supplied by the purchaser when ordering gaskets: a) the number and Part of this European Standard, i.e. EN 15 14- 1 ; b) gasket type designation (see 4.3); c) whether the gasket is for use with pipes and fittings complying with EN 545, EN 59

46、use with water intended for human consumption (see clause 5). Page 23 EN 151 4-1 : 1997 Annex B (informative) A-deviation This European Standard is mandated under the Council Directive on the approximation of the laws of the Member States concerning pressure equipment. A-deviation: National deviatio
47、n due to regulations, the alteration of which is for the time being outside the competence of the CENKENELEC member. 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.
