Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
Chelate Fe(III)IDHA does not have oxidising properties according to the UN O.1. test criterion by the ADR/RID regulations. 
Executive summary:

The test of the oxidising properties has been carried out by a method accredited in accordance with the UN O.1: Test for oxidizing solids published in “Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Fifth revised edition, New York and Geneva, ST/SG/AC.10/11/Rev.17.”

The determination procedure consists in initiating ignition of samples which are formed into cones and constitute a mixture of the material being tested and a combustible material (cellulose) at a mass ratio of 1:1 and 4:1 by means of a glowing resistance wire of an igniter and measuring their burning time. The results obtained relate to the determined burning times of standard mixtures of potassium bromate and cellulose at mass ratios of 3:7, 2:3 and 3:2.

The average burning time for the mixture of Chelate Fe(III) IDHA and cellulose (at both mass ratios) is much longer than the average burning time for the mixture of potassium bromate and cellulose at a mass ratio of 3:7. Chelate Fe(III)IDHA does not have oxidising properties according to the UN O.1. test criterion by the ADR/RID regulations. 

Description of key information
