Applicant's summary and conclusion

Interpretation of results:
other: not highly flammable
Conclusions:
The test item has not be classified as
readily combustible solid acc. to UN class 4.1
flammable solid acc. to GHS
highly flammable solid acc. to EG 440/2008

Executive summary:

The burning rate of the test item was 2 (brief ignition and rapid extinction) as well for room temperature as well as for 100°C. In mixture with Kieselgur burning rate 5 (burning with flame) was determined for both temperatures (The last one is not relevant for classification).

The determination of the burning velocity was not required therefore.
