Radiant heat EN ISO 11612 (C)

When combining different garments together, the level of protection increases against a number of flame related risks including radiant heat.

 

The fabrics are tested according to EN ISO 11612 and code letter C measures the fabrics ability to block the radiant heat. The test results in two values; the time it takes for you to sense the heat through the fabric i.e. a temperature increase by 12°C (Perceived time RHTI12), and the time it takes for the skin temperature to increase by 24°C, (Radiant Heat transfer index RHTI24). The reaction time is the time the user has to react and move away from the source to avoid injury through burns.

Test result C1, gives you a Radiant Heat transfer index (RHTI24 - Radiant Heat Transfer Index) of 7-20 seconds. To reach C2 you need 2 or 3 layers of garments which increase the Radiant Heat transfer index (RHTI24) to20-50 seconds, i.e. it increases the protection from the source.
