This Part of this British Standard describes
methods to be used on site for obtaining from a
batch of fresh concrete representative samples of
the quantity required for carrying out the tests and
making test specimens in accordance with other
Parts of this British Standard together with a
procedure for determining sampling errors using
cube compressive strength test results.
methods specified apply to concrete made with
aggregate having a nominal maximum size of no
more than 40 mm and are suitable for very low, low,
medium and high workability concretes up to workability represented by 150 mm nominal slump.
(For mixing and sampling in the laboratory,
see BS 1881-1:19702)).
