Fire protection standard BS5852

BS5852 is a British furniture fire protection standard. The content of the standard is more stringent than that of the United States. The specific use of flannel and wooden stand as testing tools is divided into four parts for testing. Usually only the first and second parts are tested. The main test cigarette butts and the use of acetylene flame to simulate match testing, as well as see the length of damage and other aspects.

The choice of flame retardant depends on the composition of the fabric
Durable finishing of cotton fabrics and synthetic fibers; so called "salt finishing" for hemp-resistant flame retardant.
An aqueous solution of a general flame retardant acts on the textile by padding or spraying. As the flame retardant salt-like precipitates settle on the fibers, an endurable flame retardant effect can be obtained. According to the composition of the flame retardant, anti-dry cleaning effect can also be obtained.
For semi-durable finishing of cotton and cotton/polyester blends, decorative fabrics shall comply with BS5852;

The BS5852 standard does not require a wash-resistant flame retardant effect, but it must be able to withstand specific flooding tests. Soak test according to BS5852 standard. That is, the finished fabric is required to be treated in a warm water bath at 40°C for 30 minutes. Then flame retardant test according to BS5852 standard test process fabric does not bear mechanical pressure: use special "salt products" to meet these requirements. Apply this compound to fabrics. Baking at 150°C to 170°C for 3 minutes to 4 minutes. Curing treatment causes mild crosslinking and resists water soaking, but this flame retardant effect is not durable.

Flame-retardant fabrics in the prevention of fire has a good protective effect, fire-retardant overalls can effectively reduce the fire and sputter metal droplets on the human body injury - YuLong Safety
