The work of pre
9、paring International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in
10、 liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC
11、 Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility t

16、and marine services.This International Standard specifies face-to-face and centre-to-face dimensions of valves for ships and marine services including supplementary series of special valves under Standards for ships, other than those specified in ISO 5752:1982 for variety of types and series of gene
17、ral industrial valves.The tables of face-to-face dimensions in this International Standard and those specified in ISO 5752:1982 represent a considerable rationalization of international practices for metallic valves to be used worldwide in the shipbuilding and marine services. The pressure/temperatu
18、re ratings for the different types of valves are those to be specified in the valve product standards for the types of valve and materials used.

19、-face dimensions1 ScopeThis International Standard specifies the basic series of face-to-face or centre-to-face dimensions for two-way metal valves used in flanged pipe systems for ship and marine services. Each series of face-to-face or centre-to-face dimensions can be used as required with flanges
20、 of mating dimensions conforming to ISO 7005-1, ISO 7005-2, and ISO 7005-3 or other national standards.The range of pressure ratings, in “K” values, is 5 - 10 - 16 - 20 - 30 - 40 and those specified in ISO 5752.The range of nominal sizes, in “DN” or “A” values, is 15 - 20 - 25 - 32 - 40 - 50 - 65 -
21、80 - 100 - 125 - 150 - 200 - 250 - 300 - 350 - 400 - 450 - 500 - 550 - 600 - 650 - 700 - 750 - 800 - 900 - 1 000 - 1 200.NOTE For information, pressure ratings at room temperature (cold ratings up to 120 C) of K-series flanges are approximately as follows.Pressure class 5K 10K 16K 20K 30K 40KPressur
