- Executive summary:
A preliminary and a main test were performed with mixtures of the test substance and the reference substance barium nitrate with cellulose powder according to Directive EC 440/2008 A.17.
The highest burning rate of a mixture of test item with cellulose (0.96 mm/s) is lower compared to the highest burning rate of a mixture of barium nitrate with cellulose (1.18 mm/s). Due to this result, the test item 7-Aminocephalosporanic acid has no oxidizing properties according to Directive EC 440/2008 A.17.
