Foreword
The Annex A, Annex B, and Annex C in this Part are recommendatory; the rest
are compulsory.
GB 567 “Bursting disc safety devices” is divided into four parts.
- Part 1. Basic requirement;
- Part 2. Application,selection and installation;
- Part 3. Classification and mounting dimensions;
- Part 4. Type test.
This Part is part 3 of GB 567.
This Part is drafted according to the rules given in GB/T 1.1-2009.
This Part replaces GB/T 12353-1999 “Classification and mounting dimensions for
domed metal bursting disc devices” and GB/T 16181-1996 “Bursting disc devices -
Type and outline dimensions for holders”. Compared with GB/T 12353-1999 and GB/T
16181-1996, the main technical changes of this Part are as follows.
- The standard name is changed from “Classification and mounting dimensions for
domed metal bursting disc devices” and “Bursting disc devices - Type and outline
dimensions for holders” into “Bursting disc safety devices - Part 3. Classification
and mounting dimensions”.
- The applicable bursting pressure range of bursting discs in this Part is expanded
from 0.01 MPa ~ 35 MPa to 0.001 MPa ~ 500 MPa;
- ADD the chapter of terms and definitions.
- ADD the flat and graphite bursting discs;
- AMEND and SUPPLEMENT the specifications for classifications, types, and code
names of holders; CHANGE the “Outline dimensions for holders” into the
“Mounting dimensions for holders”;
- ADD Annex A “Classifications, types, and code names of bursting discs”, Annex B
“Classifications, types, and code names of holders”, and Annex C “Mounting
dimensions of bursting disc safety devices”.

Bursting disc safety devices -
Part 3. Classification and mounting dimensions
1 Scope
1.1 This Part of GB 567 specifies the technical requirements such as classifications,
types, code names, marking methods, and mounting dimensions of bursting disc
safety devices.
1.2 This Part is applicable for the following bursting disc safety devices.
- This Part is applicable for the bursting disc safety devices used by pressure
vessels, pressure pipelines or other sealed pressure-bearing equipment
(hereinafter referred to as pressure-bearing equipment) to prevent over-pressure
or the appearance of excessive vacuum.
- This Part is applicable for the bursting disc safety devices of which the bursting
pressure is not higher than 500 MPa and not lower than 0. 001 MPa.
1.3 This Part is not applicable for the following bursting disc safety devices.
- The pressure-bearing equipment that may appear pressure explosion, and reach
the detonation reaction velocity during the operation process.
- The bursting disc safety devices used in national defense military equipment which
have special requirements.
Note. Phenomenon that is generated very differently from the common burning and explosion
when the burning rate of the material is quickly, above 1 000m/s, is known as detonation.
