- 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:
- The test item could not be ignited with a flame.Therefore, the performance of the main test was not necessary.The test item is not a highly flammable solid.
- Executive summary:
Study performed for flammability in accordance with EU Method A.10 (Flammability (Solids)) and UN Manual of test and criteria, rev.5, N.1.
The test item is loosely filled into a mould. The mould is made of metal, has a length of 250 mm and a triangular cross section with an inner height of 10 mm and an inner width of 20 mm. On both sides of the mould in a longitudinal direction two metal sheets are mounted as lateral limitations which project 2 mm beyond the upper edge of the triangular cross section. The mould is dropped three times from a height of 2 cm onto a solid surface. If necessary the mould is filled up again. Then the lateral limitations are removed and the excess substance is scraped off. A non-combustible and non-porous plate is placed on top of the mould, the apparatus is inverted and the mould is removed.
As ignition source a flame is used to ignite the pile at one end.
Preliminary test
In a preliminary test the burning behaviour over a distance of 200 mm is measured. One end of the pile is ignited. If the pile does not ignite after 2 min (5 min for metals) of contact with the flame or the pile burns over a distance of 200 mm in more than 4 min (40 min for metals) and 2 min (20 min for metals), respectively, the main test is unnecessary. In all other cases the main test has to be performed.
Main test
In the main test the burning rate is measured over a distance of 100 mm, after a preliminary burning distance of 80 mm. Additionally 1 ml of a wetting solution is added to the pile 30 - 40 mm beyond the 100 mm timing zone (not for metals). The test has to be repeated five times, unless a positive result is obtained earlier.
Results
The test item could not be ignited with a flame.
Therefore, the performance of the main test was not necessary.
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.
Reference
Preliminary test
The test item could not be ignited with a flame.
Therefore, the performance of the main test was not necessary.

According to these tests, the test substance is not highly flammable or readily combustible
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The test item could not be ignited with a flame.
Therefore, the performance of the main test was not necessary.
The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.
