Results and discussion

Flammable solids

Key result

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

Any other information on results incl. tables

Preliminary test:

At one end of the pile a flame is applied for maximum 2 minutes. lf the pile bums over a distance of 200 mm within 2 minutes, the main test has to be performed. lf there is no ignition of the test item

after 2 minutes of contact with the flame or the pile bums less than 200 mm within 2 minutes, the main test is unnecessary.

 

Main test:

At one end of the pile a flame is applied. After the pile has burned over a distance of 80 mm, the rate of burning is measured over the next 100 mm. The test is performed six times, using a clean

cool plate each time.

 

Apparatus:

• Mould: L x W x H: 250 x 20 x 10 mm

• Non-combustible, non-porous plate

 

 

Individual Results

 

Preliminary test:

The test item could not be ignited with a flame. The test item melted. The performance of the main test was not necessary.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Due to the burning behaviour the test item has not to be classified as a "readily combustible solid", class 4.1, of the UN transport regulations.
