    Abstract - (Show below) - (Hide below)

    Describes a procedure for determining the bulk factor of moulding materials which is used in the design of moulds.

    Scope - (Show below) - (Hide below)

    This International Standard 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 of a moulding material is of value as a basis for the calculation of minimum cavity volume in the design of moulds.
