Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
GLP compliance:

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

Results

 

Preliminary Test

In the preliminary screening test the substance was not ignited by a hot flame from a gas burner. The test item melted.

 

Main Test

In the preliminary test the test item could not be ignited by a flame. Therefore, the performance of the main test was not necessary.

 

Final Results

The test item has not to be classified as a readily combustible solid of the UN-class 4.1.

Description of key information

non flammable

no pyrophoricity

not flammablility on contact with water

not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

No ignition in the preliminary burning rate test (UN Test N.1)

Based on experience in handling and use pyrophoricity and flammability on contact with water are not to be expected.

The substance has a melting point of 64.8 °C; self-heating behaviour is not relevant for substances that are completely molten at 160 °C.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:

No ignition in the preliminary burning rate test (UN Test N.1).

Based on experience in handling and use pyrophoricity and flammability on contact with water are not to be expected.

The substance has a melting point of 64.8 °C; self-heating behaviour is not relevant for substances that are completely molten at 160 °C.
