BS 812-103.1:1985

This British Standard, a section of the BS 812 series, describes two methods for the determination of the particle size distribution of samples of aggregates and fillers by sieving.

Removal of fine material by decantation has been made the preferred method in this revision of this British Standard to ensure reliable testing of aggregate containing fine material that may cause agglomeration of particles.

In this revision the masses retained at the completion of sieving have been rationalized.
