标准范围

指定一种根据未模塑材料的表观密度和模塑材料的密度确定模塑材料体积系数的方法。在模具设计中，了解体积系数对于计算最小型腔体积非常重要。体积系数由根据ISO 1183确定的模制形式的材料密度和根据ISO 60或61确定的未模制形式的材料表观密度的商给出。

Specifies a method of determining the bulk factor of a moulding material from its apparent density in the unmoulded form and its density in the moulded form. Knowledge of the bulk factor is of importance for the calculation of the minimum cavity volume in the design of moulds. The bulk factor is given by the quotient of the density of the material in the moulded form, determined according ISO 1183 and the apparent density of the material in the unmoulded form, determinded in accordance with ISO 60 or 61.
