    Abstract - (Show below) - (Hide below)

    Gives a method of specifying requirements for all propylene (mol/mol) of propylene and compositions thereof, in powder form, granules or pellets. Also covers compositions modified by colourants, additives and fillers.

    Scope - (Show below) - (Hide below)

    This British Standard describes a method of specifying requirements for all propylene homopolymers, co-polymers of propylene containing at least 50 % (mol/mol) of propylene and compositions thereof, in the form of powder, granules or pellets including compositions modified by colourants, additives and fillers.

    NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
