Type of information:
experimental study
Adequacy of study:
key study
Study period:
February 25, 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
Qualifier:
according to guideline
Guideline:
other: UN Manual of test and criteria, rev.5, N.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Test procedure:
burning rate test: preliminary screening test
Burning time:
0 s
Moisture (wt %):
7.2
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
Remarks:
The test item smouldered for approximately 4 min in the preliminary burning distance without propagation.

 Preliminary test


The test item could not be ignited with a flame. The test item smouldered for approximately 4 min in the preliminary burning distance without propagation.


Therefore the performance of the main test was not necessary.


 

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item could not be ignited with a flame.
Executive summary:

The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

The test item is not a readily combustible solid in the sense of UN Manual of Test and Criteria, Method N.1.

Due to these results the test item does not have to be classified as “readily combustible solid”, class 4.1 of the Recommendations on the Transport of Dangerous Goods / Manual of Tests and Criteria.

Due to these results the test item does not have to be classified as “flammable solid” according to chapter 2.7 [1] of the GHS (CLP) regulations.

Description of key information

The flammability of the test item was determined according to the European Commission Regulations (EC) No. 440/2008, A.10. Flammability (solids) and UN Manual of test and criteria, rev.5, N.1 Test method for readily combustible solids.
The test item could not be ignited with a flame.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The test item could not be ignited with a flame. The test item smouldered for approximately 4 min in the preliminary burning distance without propagation.


Therefore the performance of the main test was not necessary.

Justification for classification or non-classification

The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.

The test item is not a readily combustible solid in the sense of UN Manual of Test and Criteria, Method N.1.

Due to these results the test item does not have to be classified as “readily combustible solid”, class 4.1 of the Recommendations on the Transport of Dangerous Goods / Manual of Tests and Criteria.

Due to these results the test item does not have to be classified as “flammable solid” according to chapter 2.7 of the GHS (CLP) regulations.
