Oxidizing Solids Classification Test O.1/O.3

Oxidizing solids classified under the various entries in Table A of Chapter 3.2 shall be assigned to packing groups I, II or III on the basis of test procedures of the Manual of Tests and Criteria, Part III, sub-section 34.4.1 (test O.1) or sub-section 34.4.3 (test O.3).


Oxidizing properties of solid compounds are investigated and determined for its classification for transportation and handling. Oxidizing properties are related to Division 5.1 of UN Recommendations on the Transport of Dangerous Goods. 


Tested sample is mixed with standard fuel and heated by standard energy supply. Burning time of the mixture is recorded. Obtained test time is compared with burning times of calibration mixtures. Standard oxidizing substance and fuel are used in different ratios to prepare calibration mixtures. Packing group classification of the tested sample is presented as a test result.
