Sampling test cubes

[kchadee]

Hello.
Can anyone please tell me how do we sample concrete from ready mixed trucks (say 20 trucks) for making test cubes (say 150mmx150mm).
In my country we use british standard.

Why not check the British Standard to find out the procedures?

Concrete testing is to be carried out in accordance with BS 8500-1, Annex B.

There is also Concrete Advice No.30 which is a publication from The Concrete Society which gives guidance on indentity testing for strength in accordance with BS EN 206-1 and BS 8500-1.
