Performance of the Study

The preliminary screening test was performed for the determination of the flammability of the test item.

The test item was loosely filled into an aluminium mould of 250 mm long with a triangular cross-section of inner height of 10 mm and width of 20 mm. On both sides of the mould in a longitudinal direction two metal plates were mounted as lateral limitations that project 2 mm beyond the upper edge of the triangular cross section. The mould was dropped three times from a height of 2 cm onto a solid surface. If necessary, the mould was filled up again. The lateral limitations were removed and the excess substance was scraped off. A non-combustible and non-porous plate was placed on top of the mould. The complete assembly was inverted and the mould removed.

A flame of a gas burner was applied to one end of the test item pile until the test item ignited. The pile was visually interpreted for propagation of combustion either by burning with a flame or smouldering. If applicable, the time of burning over a distance of 200 mm was measured after the pile had burned a distance of 50 mm.

Interpretation

If the test item does not propagate combustion along 200 mm of the pile within the 2 minutes test period the test item is considered ‘not flammable’.

Results

The flame of the gas burner did ignite the test item pile. The test item melted, glowed, burned with a blue yellow flame and turned into a black charred residue. Grey smoke was observed. The time of burning over a distance of 34 mm after the pile had burned a distance of 50 mm was 120 seconds. According to this, the burning rate test was not performed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The preliminary screening test was performed for the determination of the flammability of EMULTOP IP.
No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not flammable’.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item isconsidered ‘not flammable’.
