Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From January 17, 2019 to April 16, 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)

GLP compliance:

yes

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

In preliminary screening test, CR SB33 does not ignite for a maximum 2 minutes.

Interpretation of results:

GHS criteria not met

Conclusions:

According to UN Manual of Tests and Criteria: Test N.1, CR SR94 is not a highly flammable solid. Therefore, CR SR94 was not met GHS criteria.

Executive summary:

The flammability properties of CR SR94 was determined according to UN Manual of Tests and Criteria: Test N.1. In preliminary screening test, CR SR94 could not be ignited within 2 minutes. Therefore, CR SR94 is not classified as flammable solid.
