Dialuminium chloride pentahydroxide

Flash point

Some information in this page has been claimed confidential.

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is inorganic

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Cross-reference

Cross-reference 1

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

White crystalline solid, as a coarse powder, consisting of single particles, of irregular shape.

Physical state at 20°C and 1013 hPa:

solid

A fully reliable description of the substance is available from an experimental report, and is considered as key data.

Supporting observation under microscope is also provided for additional information.

Cross-reference 2

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Decomposes without melting up to 400°C.

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study. Crystal water loss was observed from ca 75°C, but no melting occured up to 400°C. Therefore, the result is expressed as a limit value, and cannot be retained as key data for purpose of CSA.

Cross-reference 3

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

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.
