Any other information on results incl. tables
Burning Rate of barium nitrate / cellulose of 50% / 50%, 60% / 40% and 80% / 30% were tested. 60% / 40% shows the highest burning rate of 3.25 mm/s.
Burning Rate of substance / cellulose of 10% / 90% was tested and the burning rate was 1.77 mm/s. Because the burning rate was lower than the highest burning rate of the reference substance no other mixtures with the substance were tested but 10% / 90% repeated five times. Mean of the burning rates was 1.71 mm/s.
Applicant's summary and conclusion
- Interpretation of results:
- other: Test substance is considered to have no oxidising properties.
- Conclusions:
- The highest burning rate of the mixture test substance/cellulose with the highest burning rate was determined to be 1.71 ± 0.05 mm/s. The maximum burning rate of the reference substance was determined to be 3.25 mm/s. Therefore, the test substance is considered to have no oxidising properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
