摘要：

Apparent mass differences due to free convection were measured for 1 kg mass standards. The observed temperature dependence was analysed, also that of some 20 g artefacts reported earlier. A model based on estimates of the convective heat transfer rate and the overall average velocity of the convective air current was used to interpret the experimental results.
