Foreword
All technical content of this standard is mandatory.
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GA 667-2006 "Explosion-proof Composite Glass". Compared with GA 667-2006, except for editorial changes, the main technical changes are as follows.
---Modified the standard name;
---Modified the terms and definitions of anti-explosive transparent materials and penetration (see 3.1, 3.2, 3.1 and 3.2 of the.2006 edition);
---Added the terms and definitions of explosion center, explosion distance, shock wave overpressure peak, proportional distance, non-contact explosion, and contact explosion (see 3.3~3.8);
---Revised the explosion-proof performance classification, explosion-proof performance classification and product code (see Chapter 4, Chapter 4 of the.2006 edition);
---Added the logo (see 5.2);
---Increase the size and deviation (see 5.3);
---Modified the requirements of light transmittance (see 5.4, 5.2 of the.2006 edition);
---Modified the explosion-proof performance test content (see 5.5, 6.5, Appendix A, 5.3, Chapter 6, and 7.3 of the.2006 edition);
---Modified the inspection rules (see Chapter 7, Chapter 8 of the.2006 edition);
---Modified packaging, transportation and storage (see Chapter 8, Chapter 9 of the.2006 edition).
This standard was proposed by the Science and Technology Information Technology Bureau of the Ministry of Public Security.
This standard is under the jurisdiction of the Sub-Technical Committee for Physical Protection Equipment (SAC/TC100/SC1) of the National Standardization Technical Committee for Security and Alarm System.
