1. CCC identification. Class A fire-proof glass corresponds to heat-insulating fire-proof glass (composite fire-proof glass). This kind of fire-proof glass can only be sold after the national compulsory product certification is passed, and the product must have this mark as the qualified product. Class C fire-proof glass is non-insulated (monolithic fire-resistant glass), and this type of glass does not need to pass mandatory certification.

2. Product type identification. In "safety glass for building Part 1: fire glass GB15763.1-2009", it is clearly stipulated that the marking method of composite fire glass is: FFB, and monolithic fire-resistant glass is marked as: DFB. For example, FFB-25-A1.50 (composite fireproof glass, nominal thickness is 25mm, fire resistance and heat insulation are Class A, fire resistance time is 1.5 hours), the first item indicates the product structure type, the second item indicates the nominal thickness of fireproof glass, and the third item indicates the fire resistance of fireproof glass and the time expressed in hours. No matter which type of fire-proof glass each piece needs to be strictly marked according to the above specifications.

3. Company logo. Qualified fire glass manufacturers all have formal production and sales qualifications, and must have their own brands. The company logo represents the company brand, however, non-standard small factories have no response signs and specifications.
Yes, generally on the right side of the glass, it is a plastic label.
Fire-proof glass, whose function in fire prevention is mainly to control the spread of fire or smoke isolation, is a kind of measure-type fireproof material, and its fire-proof effect can be evaluated by fire resistance. It is a special glass that can maintain its integrity and heat insulation in the specified flame resistance test after special processing and processing. The original sheet glass of fire-proof glass can be made of float flat glass, tempered glass and composite fire-proof glass with monolithic fire-resistant glass.
CCC ID. Class A fire-proof glass corresponds to thermal insulation fire-proof glass (composite fire-proof glass). Such fire-proof glass can only be sold after the national compulsory zhidao product certification is passed.
The product must have this mark to be a qualified product. Class C fire-proof glass is non-insulated (monolithic fire-resistant glass), and this type of glass does not need to pass mandatory certification.
There is no 3C mark for fire-proof glass, and the signs of fire-proof glass are customized by fire-proof glass enterprises. Generally, they are the company trademarks!!
