EnglishExplain the key points of identification on fireproof glass
It is a 3C product with national compulsory certification, and it is also a special glass with key monitoring in the field of architectural glass. The national department has also successively promulgated the standard of fire-proof glass, which has specifically defined its production from the source (company qualification), quality inspection (burning inspection by institutions), sales (qualified inspection speech), completion acceptance (fire maintenance), etc., which shows the importance and wide application of fire-proof glass. 1. CCC certification mark. Class a fire-proof glass, i.e. heat-insulating fire-proof glass (composite fire-proof glass), can be produced, sold and used only after passing the national compulsory product certification, and the products must have the national CCCF certification mark. Secondly, class C fireproof glass is non insulated fireproof glass (single piece fireproof glass). This kind of glass does not need to pass the national compulsory product certification of fire protection, but can pass the national compulsory product certification of glass CCCS. What needs to be clear is that since March 2018, CNCA has reformed the compulsory product certification marks, and all the compulsory product certification marks are imposed by the same CCC. The only difference is the enterprise code under the CCC logo.
Formal 3C product mark of national compulsory certification for glass
2. Product type identification. The composite fireproof glass is clearly marked as FFB in glass for building Part 1: fireproof glass gb15763.1-2009; The single piece of 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 expressed in hours. No matter what type of fireproof glass, each piece needs to be strictly marked according to the above specifications.
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 1.5 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 expressed in hours.
3. Company logo. Qualified fireproof glass manufacturers have formal production and sales qualifications and their own brands. The company logo represents the company brand, while non-standard small factories do not respond to the logo and specifications.
