Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Version / remarks:
- 2008
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 10 min
- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Remarks on result:
- maximum pressure of 2070 kPa not reached
- Remarks:
- No mean pressure rise time could be calculated as none of the test showed a pressure rise above 2070 kPa.
- Sample tested:
- reference mixture with 65% nitric acid + cellulose (1:1 ratio)
- Parameter:
- mean pressure rise time
- Result:
- ca. 4.47 s
- Remarks on result:
- other: All measured values are within the tolerable range of + 30 % (3.13- 5.82 s) of the mean pressure rise time.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has no oxidizing properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.21.
- Executive summary:
The purpose of this study was the determination of the oxidizing properties of the test item according to: European Commission Regulation (EC) No. 440/2008, A.21. Oxidizing properties of liquids.
2.5 g of the liquid test item are mixed with 2.5 g of dried cellulose. The mixture is added, in small portions with tapping, to the pressure vessel making sure that the mixture is packed around the ignition coil and is in good contact with it. It is important that the coil is not distorted during the packing process. The bursting disk is placed in position and the retaining plug is screwed in tightly.
The power supply is connected to the external terminals of the firing plug and 10 A applied. The time between the start of mixing and switching the power is about 10 minutes. The signal produced by the pressure transducer is recorded on a computer system which allows both evaluation and the generation of a permanent record of the time pressure profile obtained (e .g. a transient recorder coupled to a chart recorder). The mixture is heated until the bursting disk ruptures or until at least 60 s have elapsed.
At least five trials are performed with the mixture of the reference substance and at least five trials with the mixture of the test item. The time taken for the pressure rise from 690 kPa to 2070 kPa above atmospheric is noted. The mean time is used for classification.
No mean pressure rise time could be calculated as none of the test showed a pressure rise above 2070 kPa. Due to the fact that the 1:1 mixture, by mass, of test item and cellulose had a mean pressure rise time higher than that of a 1:1 mixture, by mass, of 65 % (w/w) nitric acid and cellulose the test item had no oxidising properties.
