Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
GLP compliance:
no
Test material information:
Composition 1
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1997-12-16
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Reference:
Composition 0
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
Directive 92/69/EEC, A.10.
Deviations:
no
GLP compliance:
yes
Test material information:
Composition 1
Test procedure:
burning rate test: preliminary screening test
Burning time:
230 s
Remarks on result:
other: The test substance began to burn with flame. After 230 seconds the flames extinguished. In this time the test substance was burned along 40 mm of the powder train. There was no more spread out of flames.

Result of the Preliminary test

The test substance began to burn with flame. After 230 seconds the flames extinguished. In this time the test substance was burning along 40mm of the powder train. There was no more spread out of flames.

The main burning rate test is not required because the substance did not burn along 200 mm of the powder train.

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test item is classified as non flammable substance.
Executive summary:

The flammability of the test item was investigated according to EU method A.10. The substance did ignite during the preliminary screening test but did not propagate combustion along the 100 mm powder train and therefore no main burning rate test was required. The test item is therefore classified as non flammable substance.

Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
GLP compliance:
no

Description of key information

The test item is classified as non flammable substance according to EU method A.10. Pyrophoric properties are exluded based on the chemical structure of the test item.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Pyrophoric properties are exluded based on the chemical structure of the test item. Furthermore, the experience from production and handling shows that the substance does not react with water.

Justification for classification or non-classification

The flammability of the test item was investigated according to EU method A.10. The substance did ignite during the preliminary screening test but did not propagate combustion along the 100 mm powder train and therefore no main burning rate test was required. The test item is therefore classified as non flammable substance.
