Does fire-resistant glass have to have the 3C mark? As people's quality of life improves, the requirements for glass are getting higher and higher. Many people choose fire-resistant glass when installing glass, but some people don't know what the signs are for fire-resistant glass. Below I will share that fire-resistant glass must have 3C Is there a sign? Let’s take a look. Does fire-resistant glass have to have the 3C mark? 1

Does fire-resistant glass have to have the 3C mark?

Fire-resistant glass is described in Safety Glass for Buildings Part 1: Fire-Resistant Glass GB15763.1-2009. Mainly divided into Class A and Class C, the fire resistance limit is divided into 5 levels: 0.50h, 1.00h, 1.50h, 2.00h, 3.00h. When purchasing, make corresponding purchases according to the design drawing requirements. After clarifying the type and fire resistance level of fire-resistant glass, it is also very important to identify the authenticity of fire-resistant glass products. Fire-resistant glass with qualified quality usually has three parts marked on the product:

1. CCC mark

Class A fire-resistant glass corresponds to insulating fire-resistant glass (composite fire-resistant glass). This type of fire-resistant glass must pass the national compulsory product certification before it can be sold. The product must have this mark on it to be a qualified product. Class C fire-resistant glass is non-insulated (single piece of fire-resistant glass), and this type of glass does not require mandatory certification.

2. Product type identification

In "Safety Glass for Buildings Part 1: Fire-Retardant Glass GB15763.1-2009" it is clearly stipulated that the marking method of composite fire-retardant glass is: FFB, single Sheets of fire-resistant glass are marked: DFB. For example: FFB-25-A1.50 (composite fireproof glass, nominal thickness is 25mm, fire resistance and insulation is Class A, fire resistance time is 1.5 hours), the first item indicates the product structure type, and the second item indicates the nominal thickness of the fireproof glass , the third item represents the fire resistance performance of fireproof glass and the time expressed in hours. No matter what type of fire-resistant glass it is, every piece of fire-resistant glass needs to be strictly marked in accordance with the above specifications.

3. Company logo

Qualified fire-resistant glass manufacturers have formal production and sales qualifications and must have their own brand. The company logo represents the company brand and is not standardized. The small factory has no response signs and specifications. Does fire-resistant glass have to have the 3C mark? 2

Is there any mark on the fire-resistant glass?

There is no special mark on the fire-resistant glass, but GB 15763.1-2001gt; 8.1.1 regulation: each piece There should be a product mark, company name or trademark on the lower right corner of the product that is not easy to erase. Ordinary people can use this to identify whether it is fire-resistant glass.

How to buy fire-resistant glass

1. Choosing a good manufacturer is the basis for purchasing good products. Since registration as a production-type fire-proof glass enterprise is subject to fire protection, environmental protection, registered capital and other conditions, many companies selling fire-proof glass are registered as trading or sales-type enterprises, or the business scope of the license does not have the qualification to produce fire-proof glass. Some companies simply Without industrial and commercial registration, such enterprises simply do not have the production conditions, and of course it is impossible to produce qualified fire-resistant glass products.

2. When purchasing fire-resistant glass, the manufacturer is required to produce the "Certificate of Supply of Fire Protection Products". Only manufacturers with complete certificates are worthy of our trust.

3. Purchase applicable products: single piece of fire-resistant glass, which is divided into 6mm, 8mm, 10mm, 12mm, etc. according to the thickness, and divided into level I (90 minutes) and level 2 (60 minutes) according to the fire resistance level. , Level 3 (45 minutes), Level 4 (30 minutes). The specific choice should not only be determined based on strength (or thickness), but also the fire resistance grade required for fire protection acceptance.

Although fireproof glass has many functions, it can also bring good results.

However, if you buy fake fire-resistant glass, it will pose a great threat to safety once it is used. Therefore, when everyone buys fire-resistant glass, they must spend a little more thought.
