Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Study conducted in compliance with GLP and agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of relevant results.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

Remarks:

Date of Signature: 15/10/2007; Date of Inspection: 21/08/2007

Test procedure:

burning time (test type not further specified)

Remarks:

or specified in description of method

Burning time:

1 117 s

Preliminary screening test

The pile ignited and burned with a yellow flame leaving black charred remains. The pile propagated combustion over the 200mm in 18 minutes and 37 seconds.

The result of the preliminary screening test obviated the need to perform the main test.

Moisture content

	Determination A	Determination B
a)  Mass of loss bottle (g)	18.3442	21.4934
b)  Mass of loss bottle and test material (g)	19.3329	22.4984
c)  Mass of loss bottle and test material     after drying (g)	19.3200	22.4861
Moisture content (% w/w)	1.305	1.224
Mean moisture content (% w/w)	1.265

Interpretation of results:

non flammable

Remarks:

The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test in under 4 minutes.

Conclusions:

The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test in under 4 minutes.

Executive summary:

The flammability of the test substance was determined by measuring the burning rate of test material prepared as a pile of set dimensions. Testing was conducted using Method A10 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test in under 4 minutes

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

Justification for type of information:

In accordance with point 1 of Annex XI of Regulation EC No. 1907/2006 (REACH), it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicate that it does not emit flammable gases in contact with water.

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

other:

Justification for type of information:

In accordance with point 1 of Annex XI of Regulation EC No. 1907/2006 (REACH), it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicate that it does not possess pyrophoric properties.

Description of key information

Non-flammable, EU Method A.10, Tremain (2008)

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

The flammability of the test material was determined in the key study (Tremain, 2008) by measuring the burning rate of test material prepared as a pile of set dimensions. Testing was conducted using Method A.10 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test in under 4 minutes. The study was awarded a reliability score of 1 in accordance with the principles for assessing data quality set forth by Klimisch et al. (1997).

 

Furthermore, in accordance with point 1 of Annex XI of Regulation EC No. 1907/2006 (REACH), it is considered justified to omit the testing for pyrophoric properties and testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicate that it does not possess pyrophoric properties or emit flammable gases in contact with water. 

Justification for classification or non-classification

In accordance with Regulation EC 1272/2008, Annex I, the substance does not meet the criteria for classification for flammable solids, pyrophoric properties and for substances which in contact with water emit flammable gases.
