BS EN 13791:2019 supersedes the 2007 version as covered in CAS47.
To assess the in-situ compressive strength of the concrete in situations where a) there is little or no information available about the concrete used or b) there is doubt about recently supplied concrete, the taking of cores tends to be the main course of action in the UK. Unless the testing is carried out correctly, in the correct place, in sufficient numbers and with the agreement of all parties concerned, it becomes less assured and there is less confidence that the strengths obtained are a true reflection of either the characteristic in-situ compressive strength or strength class. It is recommended that this Concrete Advice is read in conjunction with the relevant Standards.
