FR-One - Safety
Standard : European EN 13773 
Official standard:
Recommended standard:
Principle:
A flame is applied to a vertically oriented test fabric to determine the burning behaviourTest method
The test is pursued according to the scheme below.
The test specimen is placed in a vertical metal frame. A propane gas flame is applied to the test sample.
- EN 1101 - Procedure to determine ignitability with a small flame
Test method:
A test specimen is oriented vertically on a specimen holder. A burner flame is applied to the specimen. The behaviour of the fabric is observed. If ignition occurs, the ignition time is recorded.
If ignition occurs, the test continues following standard EN 1102, if not, following EN 13772. - EN 1102 - Procedure to determine flame spread
Test method:
The flame is applied to the test material which is hung vertically for 10 secs. The time needed to reach three defined marked points on the specimen is noted.
The test material is categorized Class 4 or 5 based on the flame spread time. - EN 13772 - Measurement of flame spread with large ignition source
Test method:
A heat source with defined energy is applied to the back of a vertical specimen. After exposure a small flame is applied to a piece of cotton fabric wrapped around the bottom of the specimen.
Flame spread is measured by determining the time taken to reach reference points on the specimen.
Result
The test material is categorised Class 1 to 5:
