Why do we take only 1 set of cube samples when casting concrete of 5 cubic meters or less?

Question

Accepted Answer

Only 1 set of cube sample is taken at a casting of concrete of 5 or less than 5 Meter cube to save cost and time.

Taking multiple samples would increase the cost of testing.
The strength of concrete is usually consistent within a small volume.
ASTM C31 allows for only 1 set of samples for small volume concrete.
If the first set of samples fails, additional samples can be taken for verification.
