TEST TO DETERMINE THE VERTICAL BURNING RATE OF MATERIALS WITH A METHOD ACCORDING TO PN-EN ISO 6941 AND APPENDIX 8 OF REGULATION NO. 118 EKG

Principle of the method.
This test consists of exposing samples, held in a vertical position, to a flame and determining the speed of propagation of the flame over the tested material.
  
Stand for determining the vertical burning rate of interior materials
  
  
Tests may need to be conducted to either surface exposure or edge exposure, or both. On the basis of the measured burn times, is calculated the vertical flammability index.

  
Test specimen.
For each exposure condition, a minimum of six representative specimens of the product shall be tested. Three specimens shall be cut lengthwise and three crosswise. The studies shall cover materials and textile products including products processed in the form of mono-component or multi-component materials (coated, quilted, multi-layered and similar systems). Where a product has areas of its surface which are distinctly different, but each of these separate areas can satisfy the surface characteristics for essentially flat products, then more than one test set shall be conducted to evaluate the product. Therefore, the exact number of samples can be determined only after the initial examination.

Dimensions of the test specimens.
  • 560 mm long  
  • 170 mm wide.  
If the dimensions of a material do not permit taking a sample of the given dimensions the test shall be carried out, in accordance with the Technical Service, on the fitted size of the material which shall be mentioned in the test report.
