Popis:	Hectolitre mass (HLM), also referred to in some countries as bushel-, specific-, test- or hectolitre weight, is the weight of a standard volume of grain and is generally believed to be a measure of its bulk density. The effect of HLM devices from different grain producing and exporting countries (Australia, Canada, France, Germany, South Africa, United Kingdom and the United States of America) on the variance in HLM values of wheat has been investigated. It has been found that the South African device resulted in HLM values significantly lower ( P P 0.90). The possible use of calculated correction factors could therefore be investigated. An alternative is to consider the calculation of appropriate conversion tables for the devices used in Australia and South Africa. A significant ( P 0.98). Consecutive wetting and drying cycles significantly ( P
