This document specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength.<\/p>\n
This document does not give guidance on the decision to drill cores or on the locations for drilling and does not provide procedures for interpreting the core strength results.<\/p>\n
It is recommended that before coring, full agreement should be reached by all parties on the need for core testing and how the results should be interpreted.<\/p>\n
