Specific details on test material used for the study:

Identity: EC# 915-640-4
Physical state: White powder
Storage conditions: Room temperature (15 to 25°C)
Batch number: YY00F3RL01-Dry
Purity: Mixture
Expiry date: 28 June 2017

Test procedure:

burning rate test over 100 mm length

Burning time:

90 s

Remarks on result:

other: The test item ignited on application of the ignition source and burned with a gentle yellow flame. There was slow propagation along the test pile, but the flame extinguished after travelling 50 mm in 90 seconds.

Results:

The test item ignited on application of the ignition source and burned with a gentle yellow flame. There was slow propagation along the test pile, but the flame extinguished after travelling 50 mm in 90 seconds. No further testing was necessary.

Conclusions:

EC# 915-640-4 was found not to be highly flammable.

Executive summary:

The flammability (solids) of the test material 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 item 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 item 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 2 minutes and any propagation timed along 200 mm of its length.

The test item ignited on application of the ignition source and burned with a gentle yellow flame. There was slow propagation along the test pile, but the flame extinguished after travelling 50 mm in 90 seconds. No further testing was necessary.

EC# 915-640-4 was found not to be highly flammable.
