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.

[1] Chapter 2.7 of the UN Globally harmonised system of classification and labelling of chemicals (GHS), 4^th revised edition, 2011 (UN GHS) and also chapter 2.7 in the CLP regulation 1272/2008 (EU GHS).

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.
