Single Flame Source Test (BS EN ISO 11925-2:2020)

 

This method specifies a test for determining the ignitability of products by direct small-flame impingement under zero impressed irradiance using vertically oriented test specimens.

 

The test specimens are cut from a sample which is representative of the product to be tested (e.g. it shall be tested as an assembly of component and not individually). When a substrate is used a specimen must be tested with a substrate representative of the end-use application.

 

Each specimen is 250 ±2mm long and 90 ±2mm vide and are conditioned in accordance with 2.3.

 

The samples are tested with 2 exposure conditions to a 20mm flame:

  • Surface exposure – 40mm above bottom edge

  • Edge exposure – at the bottom of the specimen

A piece of wood being burnt with an exposed flame

6 samples must be tested in each exposure – a total of 12 samples.

The flame is applied for 15 or 30s, depending on the classification sought.

The pass/fail criteria for classification are spread of flame to 150mm for the application of the burner flame.
