Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
March 2016
Deviations:
no
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Version / remarks:
2015
Deviations:
no
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
Interpretation of results:
not classified based on GHS criteria
Conclusions:
No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not highly flammable’.

Description of key information

not highly flammable (EU A.10, UN N.1)

not highly flammable in contact with water (EU A.12, UN N.5, UN Appendix 6)

no pyrophoric properties (EU A.13; UN N.2, UN Appendix 6)

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Based on the chemical structure, experience in handling and the study results it can be concluded that the test substance is incapable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water.


S-600 necessitates no classification according to REGULATION (EC) 1272/2008.
