Any other information on results incl. tables

The test was performed in duplicate. The standard deviation for the 5 measurements for each of the two test runs was 0.1% which is above the set limit of <0.1% for this technique. However, this is not unexpected due to the lumpy nature of the test material and is not considered significant to the results.

Applicant's summary and conclusion

Conclusions:
The test material was determined to have a relative density of 1.50 +/- 0.01 g/cm3 at 20 C +/-0.5 C.
Executive summary:

Introduction

This study was undertaken to assess the relative density of the test material. The relative density was measured directly in accordance with OECD Guideline 109.

Results & Conclusions

The relative density of the test material was determined to be 1.50 +/- 0.01 g/cm3 at 20 C +/-0.5 C.
