Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
January 11, 2016 - February 12, 2016
Reliability:
1 (reliable without restriction)
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.
Remarks on result:
no reaction with water observed
Remarks:
corresponding to 'no' in migrated source record.

A preliminary screening test was performed on the test substance. Upon application of the flame, the test substance melted – no ignition occurred. The material was determined not to be highly flammable and no further testing was performed.

Conclusions:
The material was determined not to be highly flammable and no further testing was performed.
Executive summary:

The test was performedbased on procedures presented in the Council of the European Communities, Method A.10,Flammability (Solids)(1).

The material was determined not to be highly flammable and no further testing was performed.

Specific details on test material used for the study:
Appearance: Light brown solid
Storage conditions: Room temperature in the dark
Expiry date: September 2004
Key result
Test procedure:
burning rate test over 100 mm length
Burning time:
0 min
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:
The test substance was not highly flammable.
Executive summary:

The flammability (solids) was determined using a test mould and an ignition source.

A substance is considered to be highly flammable when the time taken for a pile of test substance to burn a distance of 100 mm, after having burned a distance of 80 mm, is less than 45 seconds under the test conditions.

The metal mould of triangular cross-section of 20 mm base and 10 mm height and 250 mm in length, was loosely filled with test substance and dropped three times from a height of 2 cm onto a solid surface. The mould was removed from its holder and excess substance scraped off with a straight edge. A ceramic tile was placed on the mould, the apparatus inverted, and the mould removed. The tile was placed behind a screen, across the line of draught in a fume cupboard.

A hot flame (minimum diameter 5 mm) was applied to one end of the pile for up to 2 minutes, and any propagation timed along 200 mm of its length.

The test substance meltedbut failed to ignite. The test substance was not highly flammable.

Description of key information

Two tests were performedbased on procedures presented in the Council of the European Communities, Method A.10,Flammability (Solids)(1).

The material was determined not to be highly flammable and no further testing was performed.

Additional information

Justification for classification or non-classification

The classification criteria in accordance with the GHS system, Annex I: 2.7.2.1. Powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys) shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN RTDG, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2,2 mm/s. As the test material did not ignite it was determined not to meet the criteria for classification and not highly flammable.
