1.1 This part of GB 567 specifies the technical requirements for the categories, types, codes, marking methods, mounting dimensions and etc. of bursting disc safety devices.
1.2 This part is applicable to the following bursting disc safety devices:
- This part is applicable to the bursting disc safety devices used for pressure vessels, pressure pipes or other sealed pressure equipment (hereinafter referred to as pressure equipment) to prevent overpressure or excess vacuum;
- The bursting pressure of bursting discs applicable in this part is not greater than 500MPa and not less than 0.001MPa.
1.3 This part is not applicable to the following bursting disc safety devices:
- Pressure equipment of which the pressure is possible to be increased abruptly in the operating process and the reaction speed reaches that during detonation.
- Bursting disc safety devices under the special requirements in the national defense military equipment.
Note: the phenomena generated very differently from the common burning and explosion when the burning rate of the material reaches above 1000m/s is referred to as detonation.
