The data of preliminary test and train test are respectively in Table 1 and Table 2.
Barium nitrate/Sample (g)
Powdered cellulose (Combustible substance) (g)
Test Results (s)
Ratio of sample to
Burning time (s)
Burning rate (mm/s)
Barium nitrate : Powdered cellulose = 3:2
Burning time: 141s
Burning rate: 1.42mm/s
According to EC REGULATION No 440/2008 Annex A.17 Oxidizing Properties (Solids), the sample is not considered as an oxidising substance. The test results are "no oxidising properties", so that hazard category in CLP is not classified.
The sample is not considered as an oxidizing substance.
The result of preliminary test shows that the sample mixture burn very slowly, so the full train test is necessary. And the result of train test shows that, for sample cellulose-mixtures containing 10 to 90 % weight of sample, the piles can be ignited in 2min, only spark spreaded slowly, and the burning times are all longer than 600s. Test result showed that the maximum burning rate of mixture of sample with cellulose is less than maximum burning rate of reference mixture 1.42mm/s.
According to EC REGULATION No 440/2008 Annex A.17 Oxidizing Properties (Solids), the sample is not considered as an oxidizing substance. The test results are "no oxidising properties", so that hazard category in CLP is not classified.
