    30、ring-joint gasket is assigned an identification number, prefixed by “R, as shown in Table 1. NOTE The nominal size(s) and Class designation) to which each identification number is relevant is given in Table 1. 4.5 Information to be supplied by the purchaser The following information shall be supplie

    31、d by the purchaser when ordering gaskets: a) the number and Part of this European Standard, i.e. EN 12560-5; b) whether a particular cross-sectional shape i.e. oval or octagonal, is required (see clause 5); c) the identification ring number (see 4.4 and Table 1); d) the material (see annex A); Addit

    32、ional information that should be supplied by the purchaser : e) the expected operating conditions for which the gasket will be used. NOTE Before ordering a gasket it is recommended that the selection of the gasket type shall be made in consultation with the gasket supplier. The selection of gasket t

    33、ype should take account of the fluid, the operating conditions, the properties of the gasket materials, the type and surface finish of the flange facing and the flange bolt loading. EXAMPLE A gasket according to EN 12560-5, oval type, with ring number R.36 in type X12Crl3 (Identification symbol S 41
