Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Qualifier:
according to guideline
Guideline:
other: UN ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6 "Screening procedures" (2009)
Deviations:
no
GLP compliance:
yes
Interpretation of results:
GHS criteria not met
Remarks:
Migrated information
Conclusions:
From a GLP-compliant statement based on structural features and experience in handling, it was concluded that the substance is not highly flammable in contact with water.
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
February 2014
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Study in accordance with EC A.10. The study lacks details of the experimental conditions and observations.
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Qualifier:
according to guideline
Guideline:
other: UN ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III Section 33.2.1 "Flammable solids" (2009)
Principles of method if other than guideline:
UN MTC 33.2.1.4 - Test N.1 "Test method for readily combustible solids" is essentially the same as the EC A.10 test in case no (propagation of) combustion occurs in the preliminary screening test. In such a case a wetted zone (applied in the UN N.1 test) is of no relevance.
GLP compliance:
no
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Remarks on result:
other: not highly flammable' by ignition.
Interpretation of results:
other: 'not highly flammable' by ignition
Conclusions:
The substance has been determined to be 'not highly flammable' by ignition in the EC A.10/UN N.1 test.
Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Qualifier:
according to guideline
Guideline:
other: UN ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6 "Screening procedures" (2009)
Deviations:
no
GLP compliance:
yes
Interpretation of results:
GHS criteria not met
Conclusions:
From a GLP-compliant statement based on structural features and experience in handling, it was concluded that the substance has no pyrophoric properties.

Description of key information

Not highly flammable by ignition (EC A.10/UN N.1)

Not highly flammable in contact with water and no pyrophoric properties (based on structural features and experience in handling)

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

-Because not flammable by ignition in the UN N.1 test, no classification is required for the CLP hazard 'Flammable solid'.

-Based on structural features and experience in handling, no classification is required for the CLP hazards 'Pyrophoric solids' and 'Substances which in contact with water emits flammable gases'.

-Because of the melting temperature < 160°C, the substance need not be considered for CLP classification in the 'Self-heating substances' class.
