Best Practice Guidelines for Compressive Strength Testing of Concrete
When assessing the compressive strength of concrete, three test cylinders are required for each test from the same sample of concrete. This may be reduced to two specimens when analysis of strength results shows that the within test coefficient of variation is less than 4% as defined by NZS 3104 and NZS 3112 Part 2.
