ISO 11925-2:2020
Reaction to fire tests — Ignitability of products subjected to direct impingement of flame — Part 2: Single-flame source test
This document specifies a method of test for determining the ignitability of products by direct small flame impingement under zero impressed irradiance using vertically oriented test specimens.
Information on the precision of the test method is given in Annex A (informative).
Information on testing not essentially flat end-use products is given in Annex B (normative).
Information on testing perforated end-use products is given in Annex C (normative).
