Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From March 26, 2020 to April 22, 2020

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)

Phenomena and results from two independent preliminary screening tests, were identical as following:

-the sample was ignited within 2 min;

-after removal of ignition, the sample didn't propagate combustion either by burning with flame or smouldering along 200 mm of the train within the 2 min.

Interpretation of results:

GHS criteria not met

Conclusions:

According to UN Manual of Tests and Criteria: Test N.1, CR SB3A is not a highly flammable solid. Therefore, CR SB3A was not met GHS criteria.

Executive summary:

The flammability properties of CR SB3A was determined according to UN Manual of Tests and Criteria: Test N.1. In preliminary screening test, CR SB3A could not be ignited within 2 minutes; after removal of ignition, the sample didn't propagate combustion either by burning with flame or smouldering along 200 mm of the train within the 2 min. Therefore, CR SB3A is not classified as flammable solid.

Description of key information

CR SB3A is not classified as flammable solids (UN Test N.1).

Key value for chemical safety assessment

Flammability:

not classified

Additional information

In preliminary screening test, CR SB3A could not be ignited within 2 minutes. Therefore, CR SB3A is not classified as flammable solid.
