The mean pressure rise time of the measurements where 2070 kPa could be reached is 20.45 s. All measured values are within the tolerable range of± 30% ( 14.32 - 26.59 s) of the mean pressure rise time.

Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
The test item has no oxidising properties under the test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.21.
Executive summary:

Oxidiertes Fischöl was tested for oxidising properties according to A.21. Oxidising properties of liquids (not GLP).

Due to the fact that the 1:1 mixture, by mass, of test item and cellulose has a mean pressure rise time higher than that of a 1:1 mixture, by mass, of 65 % nitric acid and cellulose the test item has no oxidising properties.

Oxidiertes Fishchöl has no oxidising properties under the test conditions in the sense of the EuropeanCommission Regulation (EC) No. 440/2008, Method A.21.
