SOILS

as defined by BS1377:Part 1:1990

FINE Grained Soils contain not more than 10% material retained on a 2mm test sieve.

MEDIUM Grained Soils contain more than 10% material retained on a 2mm test sieve but not more than 10% retained on a 20mm test sieve.

COARSE Grained Soils contain more than 10% material retained on a 20mm test sieve but not more than 10% material retained on a 37.5mm test sieve.

Soils with greater than 10% material retained on the 37.5mm sieve are outside the scope of BS1377 but may in some cases be classed as Aggregates.
