This standard replaces the withdrawn EN533 standard.

This International standard specifies the performance requirements for
the limited flame spread properties of materials and protective
clothing.

 

The aim is to reduce the possibility of the clothing burning
and thereby itself constituting a hazard. The test results are graded
with three indices:

1. The flame does not spread, there are no flaming debris, no
afterglow, a hole may be formed.
2. The flame does not spread, there are no flaming debris, no
afterglow, no hole formation.
3. The flame does not spread, there are no flaming debris, no
afterglow, no hole formation, the afterflame times of each
individual specimen is less than 2 seconds.
