1 Scope
1.1 This part of GB 567 specifies the basic technical requirements for the application, selection and installation 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.
- As for the bursting discs in the bursting disc safety devices applicable in this part, the bursting pressure shall not be greater than 500MPa and not be 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: detonation: the phenomenon generated very differently from the common burning explosion when the burning speed of material is as quick as above 1000m/s.
