Applicant's summary and conclusion

Executive summary:

Preliminary screening test: The substance was not ignited by the gas flame. No further testing was required.

Dipivalate (ZK 00092136, batch 52542501) should not be considered as highly flammable

Mean particle size: 4.7 μm

Additional remarks:

During the preliminary screening test a melting of the substance was observed. The molten substance began to burn.

After removing the burn-flame the burning of the substance stopped.
