Applicant's summary and conclusion
- Conclusions:
- The density of the test item has been determined to be 1.36 x 1000 kg/m3 at 22.8 ± 0.5 °C.at 22.8 ± 0.5 °C. The corresponding relative density has been calculated to be 1.36.
Although testing would be preferable at 20 °C, this was not possible in the absence of methods of temperature control for the relevant apparatus. Due to the negligible influence of temperature on the density of solids, the method guideline (EC A3) requires that the determination of density of solids is to be performed "at room temperature". It is therefore considered that the effect of temperature within normal laboratory conditions will not have a significant impact on either the determined density or calculated relative density.
The density of a material varies with temperature and pressure. However, this variance is typically negligible for solids within a narrow temperature range. Typical thermal expansion coefficients of solids are in the order of 10e-5 °C(-1) and the volumetric expansion of stainless steel (used for calibration) at 20 °C is approximately 5.2 x 10e-5 °C (-1). Thus, a change in temperature of several degrees will have no significant effect on the volume and hence the density of a solid substance.
Two determinations were performed to ensure a reproducibility of less than ± 20 kg/m3 was obtained.
