REAKTIV-ORANGE DYPR 1410

Flammability

Link to relevant study record(s)

Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

04 November 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

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 not be ignited with a flame. The main test is therefore unnecessary.

Interpretation of results:

GHS criteria not met

Conclusions:

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

Executive summary:

The purpose of the test was the determination of the fiarnmability (solids) according to Guideline 92/69/EEC Part A.10. Flammability (Solids). Study conducted in compliance with GLP.

 

In case of powder and granular substances the product in its commercial form is loosely filled into a mould. The mould is made of metal, has a length of 250 mm and a triangular cross section with an inner height of 10 mm and an inner width of 20 mm. On both sides of the mould in a longitudinal direction two metal sheets are mounted as lateral limitations which project 2 mm beyond the upper edge of the triangular cross section. The mould is then dropped three times from a height of 2 cm onto a solid surface. If necessary the mould is then filled up again. Then the lateral limitations are removed and the excess substance scraped off. A non-combustible and non-porous plate is placed on top of the mould, the apparatus inverted and the mould removed.

As ignition source a flame is used to ignite the pile at one end.

 

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.

 

The substance could not be ignited with a flame.

The main test is unnecessary because the test substance could not be ignited.

 

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