- Executive summary:
Palladium dihydroxide is tested for oxidising properties using UN-Test O.1. Comparing the mean burning times of the sample mixtures with cellulose (t1 and t2) with the mean burning time of the reference mixture (R1), t1 or t2 are <R1. Therefore, it is concluded that palladium dihydroxide fulfils the classification criteria of Division 5.1 "Oxidizing substances", Packing group III, according to the Transport classification or hazard class 'oxidising solids', category 3, according to CLP.
Reference
The sample was a powder according to the sieve analysis 26% of the particles were smaller than 500 µm. The sample was ground for 5 minutes. After grinding, 98% of the particles are smaller than 500 µm. The ground sample was used.
Reference mixtures (ratio of potassium to cellulose (by mass):
3:7* - mean burning time (n=5) 129 s (burn-off with flames)
2:3* - mean burning time (n=5) 53s (burn off with flames)
*based on the fast burning times of the sample-to-cellulose mixture (4:1) no testing of other reference mixtures was necessary
