Testing concrete in structures. Cored specimens. Taking, examining and testing in compression (British Standard)
This European Standard specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength. NOTE 1 This European Standard does not give guidance on the decision to drill cores or on the locations for drilling. NOTE 2 This European Standard does not provide procedures for interpreting the core strength results. NOTE 3 For the assessment of in-situ compressive strength in structures and precast concrete components EN 13791 may be used.
