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. This standard applies to concrete tested under laboratory

This is sometimes used for conformity testing of concrete that will be in thick sections – initial slow heat development followed by standard curing. The standard allows this, but the precise regime must be agreed between the specifier and the tester. It covers the entire lifecycle of the specimen

After compaction, strike off the excess concrete using a straightedge (trowel or plate). For cubes, the surface should be slightly proud (convex) before final smoothing. The finished surface must be flat within 0.05 mm per 100 mm (checked using a straightedge and feeler gauges).
