Status: active
Page Count: 93
ICS Code (Boilers and heat exchangers): 27.060.30
ICS Code (Protection against excessive pressure): 13.240
scope:

Tis Standardcifies requments for full borafety valves with a set pressure of 0.1 mpA (guage pressure)1) and above and with a throat diameter of 7 mm and above, and curtain area restricted safety valves with a valves seat opening diameter of 15 mm and above. This Standard is not applicable to pilot operated safety valvesm or those safety valves used for pressure vessels for refrigeration. This is a product standard, and is not applicable to applications of safety valves.

Note 1) Pressure requirements in this Standard are given in either absolute pressure or gauge pressure, whichever is appropriate for the particular requirement. Absoute pressure are given in Pa, with the indication :(absolute)" attached are given in Pa with the indication "(gauge)" attached after it.

NOTE The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 4126-1: 2013 Safety devices for protection against excessive pressurePart 1: Safety valves and Amendment 1: 2016

ISO 4126-7: 2013 Safety devices for protection against excessive pressurePart 7: Common data and Amendment 1: 2016 (Overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEC Guide 21-1.
