Flammability

Link to relevant study record(s)

Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Justification for type of information:

Investigation by the manufacturer
The susbtance is supplied in water
The dried material was heated in air to 1000 C
Attempts were made to ignite the substance

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Principles of method if other than guideline:

The susbtance is supplied in water
The dried material was heated in air to 1000 C
Attempts were made to ignite the substance

GLP compliance:

no

Specific details on test material used for the study:

Batch number of test material: B-05-3234

Key result

Test procedure:

burning rate test: preliminary screening test

Moisture (wt %):

0

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

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Non flammable and non-reactive

Executive summary:

The material has been heated in air to attempt melting point assessment and instead it appears to decompose.  There was no evidence exotherm or combustion.

Inorganic salts are not typicallly considered likely to auto-ignite on heating.

Attempt was made to ignite the solid; the substance does not ignite.

Description of key information
