Such as doubts following non-compliance of standard the interpretation of the test results and the factors that cube strength results or possible deterioration due to influence the relationship between the standard cube aggressive environments or a wish to check that the strength and the strength of the concrete in the structure strength is acceptable for a particular loading system, are also discussed.

The recommendations in this standard are intended to the drilling and testing of cores has been common provide guidance only; they are not intended to supplant practice for many years and several non-destructive engineering judgment or to inhibit the development and tests have been available, well established test methods use of other test methods. being described in BS 1881 and BS 4408.
