May 16, 2017 - May 17, 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

>= 30 - <= 120 s

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

Table 1. Results of preliminary test

Test number	Time of burning [s]	Comments
Test-1	-	After the ignition the sample charred only in the place of applying the flame of burner. The sample did not ignite. Time of applying the flame of burner: 30, 60, 120 s. Result: NEGATIVE
Test-2	-
Test-3	-

 

Since the result is negative, it is not necessary to go to the next stage of determination.

 

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item did not ignite after 30, 60 or 120 seconds. Therefore, the test item is no highly flammable.

Executive summary:

The flammability of the test item was determined according to EU method A.10, following GLP. A preliminary test was performed in order to determine if, after ignition by a gas flame, propagation by burning with flame or smouldering occurs. A hot flame from a gas burner was applied to one end of the train until the train ignites of for a maximum of 2 minutes. The preliminary results were negative and therefore, it was not necessary to go to the next stage of determinatoin. The test item was not highly flammable according to test A.10 criteria.

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
Study scientifically not necessary / other information available: The study does not to be conducted because the test substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied. The test was not performed experimentally because practical experience exists at the sponsor and the test facility, e.g. when handling small amounts of the test substance repeatedly in air during testing. The test substance is therefore regarded as not being pyrophoric.

Reference 3

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
Study scientifically not necessary / other information available: The study does not need to be conducted because the experience in production or handling shows that the substance does not react with water.

Description of key information

Key study: EU method A.10. GLP study. The test item was not highly flammable.

Flammability in contact with water: Data waiving (study scientifically not necessary / other information available): The study not need to be conducted because the experience in production of handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water.

 

Pyrophoric properties: Data waiving (study scientifically not necessary / other information available): The study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Key study: The flammability of the test item was determined according to EU method A.10, following GLP. A preliminary test was performed in order to determine if, after ignition by a gas flame, propagation by burning with flame or smouldering occurs. A hot flame from a gas burner was applied to one end of the train until the train ignites of for a maximum of 2 minutes. The preliminary results were negative and therefore, it was not necessary to go to the next stage of determination. The test item was not highly flammable according to test A.10 criteria.

Justification for classification or non-classification

Based on available information, the substance is not classified in accordance with CLP Regulation (EC) no. 1272/2008.
