Lot #: JEGX150811
Purity: 98.8% - Contact with:
- powdered cellulose
- Key result
- Sample tested:
- other: test substance and powdered cellulose in various ratios
- Parameter:
- maximum burning rate
- Result:
- 1.8 mm/s
- Remarks on result:
- other: The test substance mixture was found to char and produce white smoke
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was considered to be non-oxidising
- Executive summary:
The test is conducted to determine the oxidizing properties of a powder solid in accordance with the criteria of EC Test A17. The principle is to compare the burning rate of various ratios of the test substance/powdered cellulose mixtures against that of a reference mixture (barium nitrate/powdered cellulose).
Test substance/cellulose mixtures are prepared containing 10 to 90% by weight of test substance in 10% increments. The highest burning rate for the sample mixtures was found to be 1.8 mm/s. This is lower than the highest burning rate for the reference mixture (3.6 mm/s).
The test substance gave a negative result and is therefore not classified as an oxidizing solid. The test substance mixture was found to char and produce white smoke. It is suspected that the mixture undergoes decomposition in contact with the ignition source and this provided the false positive result observed in the initial testing.

- non oxidising
Additional information
Justification for classification or non-classification
Substance was not oxidizing in a test according to EU Method A.17; therefore, no classification is required according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
