Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
05 October 1998
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The substance could be ignited with a flame and after a distance of 90 mm in approx. 9 min. the flame went out.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test substance is not a readily combustible solid in the sense of Guideline 92/69/EEC, test A. 10.
Executive summary:

The purpose of the test was the determination of the flammability (solids) according to Guideline 92/69/EEC of 31 July 1992, Annex. Part A: Methods for the determination of physico-chemical properties. A. 10. Flammability (Solids). The study was conducted in compliance with the Principles of Good Laboratory Practice (GLP).

 

Performance of the test

Preliminary test:

Ignite one end of the pile. When the pile has burned over a distance of 200 mm during 4 minutes, the main test has to be performed. If there was no ignition of the test substance or the pile has burned slower than 200 mm during 4 minutes, the main test is unnecessary.

 

Results

The substance could be ignited with a flame and after a distance of 90 mm in approx. 9 min. the flame went out.

 

The test substance is not a readily combustible solid in the sense of Guideline 92/69/EEC, test A. 10.

Description of key information

The test substance is not a readily combustible solid in the sense of Guideline 92/69/EEC, test A. 10.
