EN ISO 11925-2 Ignitability of building products subjected to direct impingement of flame

EN ISO 11925-2:2002 Reaction to fire tests –Ignitability of building products subjected to direct impingement of flame –Part 2 Single-flame source test.

The test method is similar with GB/T 8626-2007

Test time

There are 2 ignition times for selection, 15s or 30s. Test start time is the ignition start time.
If the ignition time is 15s, the total test time is 20s, calculated from the start the ignition.
If the ignition time is 30s, the total test time is 60s, calculated from the start the ignition.

The results presentation

For each film sample, recording the following phenomena:
a) whether the sample was ignited
b) whether the flame tip reaches the ignition point of 150mm from the office, and record the time of occurrence of the phenomenon
c) whether there has been ignition of filter paper
d) observe the physical behavior of samples

EN ISO11925-2 test, B, C, D, E level require the data

B Class EN ISO 11925-2 Ignition time = 30s, 60s Fs ≤ 150mm
C Class EN ISO 11925-2 ignition time = 30s, 60s Fs ≤ 150mm
D Class EN ISO 11925-2 ignition time = 30s, 60s Fs ≤ 150mm
E Class EN ISO 11925-2 ignition time = 15s, 60s Fs ≤ 150mm
