Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

>= 2 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

Preliminary test results

The test item melted in contact with the ignition source. The melt burned locally. No propagation of the flame was observed. The performance of the main test was not necessary.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item was not a readily combustible solid in the sense of UN Manual of Tests and Criteria, Method N.1.
The test item was not a flammable solid according to
- Chapter 2.7 of the UN Globally harmonized system of classification and labelling of chemicals (GHS) 8rh revised edition, 2019 (UN GHS) and
- Chapter 2.7 in the CLP regulation 1272/2008 (EU GHS).

Executive summary:

In a GLP study conducted according to UN Manual of Tests and Criteria, Method N.1., the test item was tested on its flammability.

Since no porpagation of the flame was observed in the preliminary test, the main test was not necessary.

The test item was not a readily combustible solid in the sense of UN Manual of Tests and Criteria Method N.1.

The test item was not a flammable solid according to

- Chapter 2.7 of the UN Globally harmonized system of classification and labelling of chemicals (GHS) 8th revised edition, 2019 (UN GHS) and

- Chapter 2.7 in the CLP regulation 1272/2008 (EU GHS).
