Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

July 06, 2018 - May 3rd, 2019

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Deviations:

yes

Remarks:

A mould was not used because the paste was very sticky and it was impossible to fill it up. This deviation was not considered to have affected the quality or the interpretation of the results obtained.

GLP compliance:

yes (incl. QA statement)

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

PRELIMINARY TEST

Experimental conditions

- Atmospheric pressure: 98.4 kPa.

- Application of the flame: 2 minutes.

- Test period: 2 minutes.

Assay no. 1

The test item melted. Neither propagation nor ignition was observed.

Assay no. 2.

The same observations as for the assay no. 1 were recorded.

MAIN TEST

Taking into account the results obtained during the preliminary test, no main test was performed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

On ignition by a gas flame, the test item did not ignite and propagate combustion by burning with flame or smouldering, in a preliminary screening test. The test item was thus not classified as a flammable solid of Division 4.1 according to EC No. 1272/2008 (CLP) and no further test was required.

Executive summary:

The flammable properties of the test item were investigated in a GLP-compliant study performed in accordance with UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids). On ignition by a gas flame, the test item did not ignite and propagate combustion by burning with flame or smouldering, in a preliminary screening test. The test item was thus not classified as a flammable solid of Division 4.1 according to EC No. 1272/2008 (CLP) and no further test was required.

Description of key information

The flammable properties of the test item were investigated in a GLP-compliant study (Demangel, 2019) performed in accordance with UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids). On ignition by a gas flame, the test item did not ignite and propagate combustion by burning with flame or smouldering, in a preliminary screening test. The test item was thus not classified as a flammable solid of Division 4.1 according to EC No. 1272/2008 (CLP) and no further test was required.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammable properties of the test item were investigated in a GLP-compliant study (Demangel, 2019) performed in accordance with standard methods, with minor deviations. The study is considered as reliable without restriction (Klimisch 1) and was selected as key study for the endpoint.

Justification for classification or non-classification

On ignition by a gas flame, the test item did not ignite and propagate combustion by burning with flame or smouldering, in a preliminary screening test. The test item was thus not classified as a flammable solid of Division 4.1 according to EC No. 1272/2008 (CLP).
