Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
All validity criteria were met.
No signs of oxidising properties of the test item were detected.
The reference item showed oxidising properties very clearly and with good repeatability.
No observations were made which might cause doubts concerning the validity of the study outcome.
The result of the test is considered valid.
Executive summary:

This study was performed according to EU Method A.21 .

For the test item , five independent experiments were performed. ln none of the experiments, the bursting disc was damaged.

For the reference item nitric acid, five independent experiments were performed, too. The reference mixture showed a fast increase in pressure: 2070 kPa were surpassed within less than seven seconds in all five experiments .

NOREENAL must be considered as not oxidising, because the pressure raise of a mixture of it with cellulose 1:1 shows no faster increase than the reference mixture of nitric acid and cellulose 1:1.
