Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

The study was conducted between 09 April 2006 and 21 April 2006

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Sponsor's identification: BHES-100X
Description: white solid block
Batch number: 5K0718-CC
Date received: 21 January 2006
Storage conditions: room temperature, over silica gel, in the dark

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

5 s

Moisture (wt %):

0.631

Remarks on result:

other: The pile melted then ignited with a very small flame, which self-extinguished 5 seconds after the Bunsen flame was removed without propagating combustion.

Moisture content

	Determination A	Determination B
a) Mass of loss bottle (g)	20.8326	19.0179
b) Mass of loss bottle and test material (g)	21.9793	20.0304
c) Mass of loss bottle and test material after drying (g)	21.9722	20.0239
Moisture content (% w/w)	0.619	0.642
Mean moisture content (% w/w)	0.631

Interpretation of results:

not classified based on GHS criteria

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.

Executive summary:

The flammability (solids) was determined by measuring the burning rate oftest 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.
