1. Purchase applicable products

Composite fireproof glass is divided into 6mm, 8mm, 10mm, 12mm, etc. according to the thickness. It is divided into grade I (90 minutes), grade II (60 minutes), grade III (45 minutes) and grade IV (30 minutes) according to the fire resistance rating. The detailed selection shall not only be determined according to the strength (or thickness), but also the fire resistance rating required for fire acceptance. High strength single piece cesium potassium fireproof glass is more fire-resistant, stronger and more stable than ordinary single piece fireproof glass because it adopts chemical and physical two-layer technology.

2. Select qualified manufacturers

Because the registration of composite fire-proof glass as a consumer fire-proof glass enterprise is constrained by fire protection, environmental protection, registered capital and other conditions, many enterprises selling fire-proof glass are registered as trading or sales enterprises, or there is no qualification to consume fire-proof glass in the operation scope of the license. Some enterprises are straightforward and have not been cancelled by industry and commerce, and these enterprises basically do not have the consumption conditions, Of course, it is impossible to consume qualified fireproof glass products. The purchaser shall understand the operation status of the manufacturer through field investigation and request it to produce the original (or duplicate) of the industrial and commercial license, so as to prevent being cheated.

3. The purchased products shall have sampling inspection statements and records

At that time, the application of fire-fighting products in the fire-fighting part of the composite fire-fighting glass was more and more strict, and the consumption, sales and application units were requested to be responsible for the fire-fighting products used all their life. If the fake fire-fighting products or certificates were accidentally used, they would bear great fire-fighting acceptance risks and future accident obligation risks. According to the fire-fighting regulations, they must pass the sampling inspection of the public security fire-fighting part, Enterprises that hold the type inspection statement within the validity period of the national fire prevention building materials quality inspection center or the national fixed fire extinguishing system and fire resistant components quality inspection center can consume fire-proof glass.

The application period of the inspection statement is generally three years. The inspection statement is generally filed in the quality inspection center and the provincial fire brigade. The contact number and address of the quality inspection center shall be displayed in the inspection statement, so as to check the authenticity of the statement. The purchaser must ask whether the consumer manufacturer can produce the original inspection statement and provide the telephone and other materials of the filing institution for verification.
