This Part of SS 78 B series standards gives guidance on the tests that are available for non-destructive testing of hardened concrete which forms a laboratory specimen or part of a structure, structural component or other type of engineering construction. Some tests cause varying degrees of localized damage or defacement and may therefore be considered partially destructive; these methods are all defined as non-destructive. Ail the tests can be performed on the concrete as cast and do not require the removal of samples for subsequent analysis or testing.
Methods of testing hardened concrete which require sample extraction are either dealt with in other Parts of SS 78 B series standards or elsewhere [1,2].
NOTE 1. Damage caused by the extraction of small-diameter cores may not be significantly greater than that due to some of the near-to-surface methods included here, provided that reinforcement is not cut during extraction. In cases where strength determination is required they may offer similar or better accuracy with fewer calibration problems [3].
NOTE 2. The titles of the publications referred to in this standard are listed at the end of the standard.
