Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test item is not flammable
Executive summary:

The flammability of the substance was determined by igniting a pile of substance with the hot flame or a hot platinum wire.

The substance showed only a brief ignition but then a rapid extinction without any spreading of the flame
