Individual results
The test item contained more than 10 % of particles below 500 µm (see granulometry study M-754106-01-1 in section 4.5 of this IUCLID dossier). Therefore, the test item was ground with mortar and pistil and sieved over a 500 µm sieve. However after four times of grounding and sieving approximately 8 % were still > 500 µm. Therefore, it was considered that the remaining test item was not friable enough and both fractions (>500 µm and <500 µm) were united and taken for the measurement.
The residual moisture of the test item was determined in drying chamber at ambient temperature under vacuum. The test item had a content of residual moisture of 0 % (the test item used for the tests had not been dried).
The ambient temperature was 22 °C and the air humidity was approximately 50 % during the test.
Five tests were performed on the mixture of the reference substance with cellulose in the ratio 1:2. The results are shown in the following table.

Experiment | mCaO2 / g | mcellulose / g | t20-80 / s | BR20-80 / g/s | Observations |

5 | 10.01 | 20.00 | 55.63 | 0.22 | - |
The mean burning rate of the mixture of the reference item/cellulose 1:2 was 0.28 g/s. According to the UN manual the tolerable range is ± 20 % of the mean burning rate (0.22 - 0.33 g/s). The correlation coefficient of the mass loss as a function of time was for all experiments >= 0.90.
Five tests were performed on the mixture of the test item with cellulose in the ratios 4:1 and 1:1 . The results are shown in the following tables.
Table: Burning times of test item/ cellulose mixtures 4:1
Experiment | mtest item / g | mcellulose / g | t20-80 / s | BR20-80 / g/s | Observations |

5 | 24.03 | 6.06 | 154.9 | 0.02 | Burning and sooting |
The mean burning rate of the mixture of the test item/cellulose 4:1 was 0.03 g/s. According to the UN manual the tolerable range is ± 20 % of the mean burning rate (0.02 - 0.03 g/s). The correlation coefficient of the mass loss as a function of time was for each experiment >= 0.90.
Table: Burning times of test item/ cellulose mixtures 1:1
Experiment | mtest item / g | mcellulose / g | t20-80 / s | BR20-80 / g/s | Observations |
1 | 15.02 | 15.01 | 183.6 | 0.05 | Burning and sooting |

4 | 15.03 | 15.00 | 214.3 | 0.04 | Burning and sooting |
5 | 15.00 | 15.04 | 197.3 | 0.05 | Burning and sooting |
The mean burning rate of the mixture of the test item/cellulose 1:1 was 0.05 g/s. According to the UN manual the tolerable range is ± 20 % of the mean burning rate (0.04 - 0.06 g/s). The correlation coefficient of the mass loss as a function of time was for each experiment >= 0.90.
No tests were performed on the mixture of the reference substance with cellulose in the ratio 3:1 and 1:1 as the test item mixtures were slower than the slowest reference mixture. Due to the fact that the mixtures of test item with cellulose had a slower burning rate than the 1:2 mixture of the reference item, it was concluded that the test item had no oxidizing properties.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item, technical substance had no oxidizing properties according to UN Test O.3. The burning rates of the test item mixtures were slower than the burning rate of the 1:2 mixture of the reference item.
Due to these results the test item has not been classified as “oxidising solid”, division 5.1 of the UN manual of Tests and Criteria, revision 7 (2019).
Due to these results the test item has not to be classified as “oxidising solid” according to chapter 2.14 of the CLP regulation and GHS regulation, revision 8.
