Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

05 March 1993

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

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

The substance could not be ignited in the modified Hartmann Rohr apparatus.

The test substance is not a readily combustible solid in the sense of Guideline EEC/79/831 test A.10.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance is not a readily combustible solid, nor is there any concern for the liberation of flammable gas following exposure to water / moisture.

Executive summary:

The substance could not be ignited in the modiefied Hartmann Rohr apparatus.

The test substance is not a readily combustible solid in the sense of Guideline EEC/79/831 test A.10.

Description of key information

The test item could not be ignited with a flame; therefore the main test is not necessary

Key value for chemical safety assessment

Flammability:

non flammable

Additional information
