Under ISO/IEC 17025 (laboratory accreditation), simply following the standard is not enough – you must prove you followed it.
BS EN 12390-2:2019 is a crucial standard within the construction materials industry. It specifies the methods for making and curing concrete test specimens (cubes and cylinders) in a laboratory setting. The primary objective is to ensure that the specimens produced are representative of the concrete quality, allowing for accurate determination of compressive strength. It replaced the 2009 version and introduces stricter controls on curing conditions, temperature monitoring, and surface preparation of specimens. bs en 12390-2:2019
