The partial modification using IEC 60534-5:2004 "Industrial process control valves - Part 5. Flag" (in English).

This part of IEC 60534-5:2004 is the difference between.

--- Removed Normative references ISO 5209:1997 "Universal Valve logo" because the file is not mentioned in the provision;

--- An increase of 3 Note 4.1, an increase of nominal pressure PN series and to sign and logo in the form of a corresponding relationship between the level Department of representation;

--- Body Table 1 item 7 and 9 according to IEC 60534-5:2004 Note 2 clearly stated as follows. supplementary (S) and mandatory (M) flags side by side.

Increased content in a standard text of the provisions relating to the margin with a single vertical line identification.

For ease of use, this part of the press in the development of GB/T 1.1-2000 "Standardization Guide Part 1. Standard structure and drafting Rules "and GB/T 20000.2-2001" Standardization Guide Part 2. the relevant provisions of the rules of international standards "made as by editorial changes.

a) "IEC 60534 this part" to "GB/T 17213 in this section";

b) Remove the preface international standards;

c) a reference to the original standard key words according to the provisions GB/T 1.1-2000 changed to normative documents referenced introductory phrase;

d) Normative references A list of documents according to the provisions of GB/T 1.1-2000 re-arranged.

This Part replaces GB/T 17213.5-1998 "Industrial process control valves - Part 5. flag." the main difference between this part and GB/T 17213.5-1998 follows.

--- Update normative references;

--- Increase the nominal series of statements;

--- To increase the PN flag and mark in the form of correspondence between the expression level relationship;

--- Table reflects the mandatory signs and supplementary signs 1 position by IEC 60534-5:2004 "Industrial process control valves - Part 5.

Marks "(English version) arrangement;

--- Body Table 1 item 7 and 9 according to IEC 60534-5:2004 Note 2 clearly stated as follows. supplementary (S) and mandatory (M) flags side by side.

This part is proposed by China Machinery Industry Federation.

This part of the measurement and control of industrial processes by the National Standardization Technical Committee at its first Technical Committee (SAC/TC124/SC1) Centralized.
