适用范围：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.
