Specific details on test material used for the study:
Name: Cadmium selenide
Batch/Lot number: 270018
Appearance: Black powder
CAS number: 1306-24-7
Purity: 99.999%

Key result
Test procedure:
burning rate test: preliminary screening test
Remarks:
Test item glowed, however no ignition occurred
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

Based on the results of the preliminary test no further testing was required.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item could not be ignited. Therefore, the substance is considered not to be highly flammable.
Executive summary:

The objective of the study was to determine if the test item is flammable. The test item was formed into a powder train. It was ignited by a gas flame and the burning rate was determined.

The study was conducted in a GLP compliant laboratory in accordance with Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), Method A.10, Official Journal of the European Union L 142 of 31 May 2008.

 

Two parallel flammability tests were performed. The tests were negative. Therefore the test item is not highly flammable in the conditions of this test.

Description of key information

Key value determined in a GLP accredited laboratory study using flammability test, in accordance with EU Method A.10 (Flammability (Solids)

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The objective of the study was to determine if the test item is flammable. The test item was formed into a powder train. It was ignited by a gas flame and the burning rate was determined.

The study was conducted in a GLP compliant laboratory in accordance with Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), Method A.10, Official Journal of the European Union L 142 of 31 May 2008.

 

Two parallel flammability tests were performed. The tests were negative. Therefore the test item is not highly flammable in the conditions of this test.

Justification for classification or non-classification

Two parallel flammability tests were performed. The tests were negative. Therefore the test item is not highly flammable in the conditions of this test. Under Regulation 1272/2008, Cadmium selenide is not classified as a flammable solid.
