Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 May 2010- 5 August 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
This study has been performed according to OECD and EC guidelines and according to GLP principles. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
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

In contact with the flame of the gas burner, the test substance glowed. After removal of the ignition source, no propagation of combustion of the test substance was observed.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is NOT classified as a flammable solid according to Regulation (EC) N°1272/2008 (CLP) criteria.
Executive summary:

The substance was tested for its flammable properties, according to EU A10/UN N1 guideline, and under GLP.

Test material has been determined NOT to be a flammable solid, as it failed to propagate ignition in the preliminary screening test.

Endpoint:
self-heating substances / mixtures
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 May 2010- 5 August 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
This study has been performed according to UN TDG guideline and according to GLP pri nciples. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
Version / remarks:
2003
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
Test procedure:
100 mm sample cube at 140°C
Max. temp. reached:
140
Induction time (h):
24
Result:
negative outcome (no effect observed)

No exothermic effect of the test substance was observed. It demonstrated that the test substance is “not a self-heating substance”. According to the guideline, no further testing was required.

No changes were observed in the appearance of the test substance.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test substance is NOT a self-heating substance, based on CLP criteria.
Executive summary:

The self-heating potential of dialuminium chloride pentahydroxide was investigated according to UN N4 guideline, Bowes-Cameron cage test. No exothermic reaction was observed. Therefore this test was considered negative.

The test is relevant for classification according to CLP criteria.

Endpoint:
pyrophoric solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 May 2010- 5 August 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
This study has been performed according to OECD and EC guidelines and according to GLP principles. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
Deviations:
no
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.2 (Test method for pyrophoric solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition on contact with air (not further specified)

If the test substance ignites in one of the tests, the test substance is considered pyrophoric.

In none of tests, spontaneous ignition of the test substance occurred during dropping or within five minutes of settling. In conclusion, the test substance has no pyrophoric properties.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is NOT classified as a pyrophoric solid according to Regulation (EC) N°1272/2008 (CLP) criteria.
Executive summary:

The substance was tested for its pyrophoric properties, according to EU A13/UN N2 guideline, and under GLP.

The test material has been determined NOT to be a pyrophoric solid, as no spontaneous ignition was observed.

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
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
Reason / purpose for cross-reference:
data waiving: supporting information

Description of key information

Not a flammable solid (no propagation of combustion if contact with a flame).

Not a self-heating substance (no exothermic reaction).
Not pyrophoric.
Not flammable if contact with water. (waived)

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The substance was tested for flammablilty of solids, self-heating, and also for pyrophoric properties.

Fully reliable experimental studies, conducted according to recognized UN methods and under GLP, are presented under point 4.13. They are considered as key studies.

Based on experience, no flammable properties are anticipated if contact with water, therefore this study was deemed unnecessary.

Justification for classification or non-classification

According to Regulation (EC) No.1272/2008 (CLP) criteria:

- the substance did not propagate combustion in the preliminary test, therefore it is NOT classified as a flammable solid;

- no exothermal effect was observed when heating in the Bowes-Cameron test; therefore it is NOT classified as self-heating;

- It did not either ignite spontaneously in any of the replicates during dropping or settling in air, therefore it is NOT classified as a pyrophoric solid.
