EVS-EN ISO 11925-2:2026

ISO 11925-2 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.

Although the method is designed to assess ignitability, this is addressed by measuring the spread of a small flame up the vertical surface of a specimen following application of a small flame to either the surface or edge of a specimen for either 15 s or 30 s. The determination of the production of flaming droplets or particles depends on whether the filter paper placed beneath the specimen ignites.

 — Details on the precision of the test method is given in Annex A.
 — Details on testing not essentially flat end-use products is given in Annex B.
 — Details on testing perforated end-use products is given in Annex C.

ISO 11925-2:2026 text has been approved in Europe as EN ISO 11925-2:2026 without any changes.
