Interpretation of results:

GHS criteria not met

Conclusions:

The test item does not have oxidising properties according to method A.21 criteria.

Executive summary:

The oxidising properties of the test item were evaluated according to EU method A.21, following GLP. The test item was mixed in 1:1 ratio, by mass, with fibrous cellulose and introduced into a vessel equipped with a bursting disk. Then, an electric current was applied for 60 s in 5 different tests, and the pressure did not reach the criterial value 690 kPa. The mean pressure rise time for the mixture of the reference substance (65% aqueous nitric(V) acid) and cellulose was 5109 ± 549. The test item does not have oxidising properties.

Description of key information

Key study: EU method A.21. GLP study. The test item does not have oxidising properties.

Key value for chemical safety assessment

Oxidising properties:

non oxidising
