It is a 3C product under national compulsory certification and a special glass under key monitoring in the field of building glass. The national department has also successively announced the scale of fire-proof glass, and defined it in detail from the aspects of source production (company qualification), quality inspection (burning inspection by professional organizations), sales (qualified inspection speech), completion acceptance (fire maintenance), etc. it can be seen that fire-proof glass is important and widely used. 1. CCC certification mark. The primary class a fireproof glass is thermal insulation fireproof glass (composite fireproof glass). This kind of fireproof glass can be produced, sold and used only after passing the national compulsory product certification. The products must have the national CCCF certification mark. Secondly, class C fireproof glass, i.e. non insulated fireproof glass (monolithic fireproof glass), does not need to pass the national compulsory product certification of fire protection, but can pass the national compulsory product certification of safety glass CCCS. What needs to be clear is that since March 2018, CNCA has changed the compulsory product certification marks, and all the compulsory product certification marks are imposed by the same CCC. The only other area is the enterprise code under the CCC sign.

Fireproof glass

Formal 3C product identification of national compulsory certification of safety glass

2. Product type identification. In safety glass for construction Part 1: fireproof glass gb15763.1-2009, the composite fireproof glass is clearly marked as: FFB; The single fireproof glass is marked as DFB. For example: ffb-35-a1.50 (composite fireproof glass, nominal thickness is 35mm, fire resistance and thermal insulation is class A, and fire resistance and thermal insulation time is 1.5 hours). The first item represents the product structure type, the second item represents the nominal thickness of fireproof glass, and the third item represents the fire resistance of fireproof glass and the time indicated in hours. No matter what type of fireproof glass, each piece shall be strictly marked according to the above standards.

Dfb-6-c1.50 (single piece of fireproof glass, nominal thickness is 6mm, fire resistance and thermal insulation is class C, and fire resistance time is 1.5h). The first item represents the product structure type, the second item represents the nominal thickness of fireproof glass, and the third item represents the fire resistance of fireproof glass and the time indicated in hours.

3. Company logo. Qualified fireproof glass manufacturers have formal production and sales qualifications, and must have their own brand. The company logo represents the company brand, while non-standard small factories do not respond to the logo and standard.
