This document specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength. This document does not give guidance on the decision to drill cores or on the locations for drilling. This document does not provide procedures for interpreting the core strength results. For the assessment of in situ compressive strength in structures and precast concrete components, EN 13791 may be used.
