Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From May 16, 2018 to June 07, 2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Test procedure:
burning rate test: preliminary screening test
Burning time:
> 2 min
Remarks on result:
other: substance was ignited within 2 minutes. But the sample did not propagate combustion either by burning with flame or smouldering along 200 mm of the train within the 2 min after removal of ignition.

The preliminary screening test showed that CR SB37 was ignited within 2 minutes. But the sample did not propagate combustion either by burning with flame or smouldering along 200 mm of the train within the 2 min after removal of ignition.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
According to UN Manual of Tests and Criteria: Test N.1, CR SB37 is not a highly flammable solid. Therefore, CR SB37 was not met GHS criteria.
Executive summary:

This test using the procedures outlined in the ZCTC Study Plan for PCF2018-010-4 and UN Manual of Tests and Criteria: Test N.1.The preliminary screening test showed that CR SB37 was ignited within 2 minutes. But the sample did not propagate combustion either by burning with flame or smouldering along 200 mm of the train within the 2 min after removal of ignition. Therefore,CR SB37 is not a highly flammable solid.

Description of key information

CR SB37 is not a highly flammable solid (UN Manual of Tests and Criteria: Test N.1).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The preliminary screening test showed thatCR SB37 was ignited within 2 minutes. But the sample did not propagate combustion either by burning with flame or smouldering along 200 mm of the train within the 2 min after removal of ignition.Therefore, CR SB37 is not a highly flammable solid.
