|Expert on flame-retardant fabrics|GB – Summary of national standards
Classification:
flame retardant fabric
GB represents national standards. The Flame-retardant fabrics produced by Limited Co., Ltd. are strictly implemented in accordance with national standards; flame-retardant related What are the national standards?
GB2408-80 horizontal combustion test method:
The horizontal test method is to test the combustion performance of the sample under horizontal self-support under laboratory conditions.
GB2409-84 vertical combustion method:
The vertical combustion method is a method for classifying the combustion of vertically placed specimens with certain specifications under prescribed conditions under the action of flame.
GB2406-80 Oxygen Index Test Method:
Oxygen index (OI) refers to the low oxygen content in the required mixed gas when plastics are burned. The average concentration of oxygen in the air is 21%. Generally, the oxygen index below 21 is flammable plastic, 22-27 is self-extinguishing plastic, and above 27 is flame-retardant plastic. This method is relatively simple, has good digital reproducibility, and has the characteristics of numerically expressing the combustion performance of materials, so it is commonly used abroad, (such as the oxygen index test in the United States The standard isANST/ASTMD2863-1977). This method is not only suitable for self-supporting materials, but also for films, foam plastics, etc.
GB8323-87 Smoke Density Test Method:
This test method is to measure the specific optical density produced when the material is radiated or burned under specified test conditions. The specific optical density is the specific optical density value calculated based on the specified test box volume, optical path length, and light transmittance measured by the test area. The large optical density value is used to represent the optical density of the material.
The biggest feature of the Flame-retardant fabric produced by Limited is its excellent flame-retardant performance, and the fabric still has excellent properties after being washed. Its flame retardant performance makes it the first choice for flame retardant protective clothing.
