Interpretation of results:
Category 2 (oxidising liquids) based on GHS criteria
Conclusions:
The hydrogen peroxide samples of concentrations above 40 % H2O2 by mass fulfil the criterion of classification in Div. 5.1.
The tested samples with H202 concentrations of 42.5 %, 45.0 %, 47.3 % should be assigned to Packing Group Ill and the tested sample with H202 concentration of 50.0 % should be assigned to Packing group ll.
Executive summary:

Seven Hydrogen Peroxide samples of different concentrations were tested on their oxidizing properties according to the test O.2, test for oxidizing liquids of Division 5.1 (UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria IST/SG/AC. 10/11/ Rev.3, 1999, Part III, 34.42). The result was that only the hydrogen peroxide samples of concentrations above 40 % H2O2 by mass fulfil the criterion of classification in Div. 5.1. The tested samples with H2O2 concentrations of 42.5 %, 45.0 %, 47.3 % should be assigned to Packing group III and the tested sample with H2O2 concentration of 50.0 % should be assigned to Packing group II.

Description of key information

Hydrogen peroxide is oxidizing. It contains one of the chemical groups which are oxidizing (i.e. –O-O-; inorganic peroxide). Study report (Vorwinkle 2016a) investigated a 69.7% solution of hydrogen peroxide, this was determined to meet the criteria of a category 1 strong oxidiser under the GHS classification system. Two studies were conducted on 60 and 63% solutions of hydrogen peroxide, both solutions were classified as a category 2 oxidiser in accordance with GHS (Neis 2017, Vorwinkle 2016b). In a study reprot (Wildner 2001) hydrogen peroxide solutions (40 % 50 %) were shown between oxidising category 2 and 3, and furthermore at concentrations below 40% they were not classified as oxidising.

Key value for chemical safety assessment

Oxidising properties:
yes

Additional information
