The standard BS EN 12390-2:2019 is a critical technical document that specifies methods for making and curing specimens for strength tests of hardened concrete.
: When moving specimens to a laboratory, they must be protected from dehydration and temperature extremes using wet sand, sawdust, or sealed plastic bags. Significance in Construction The 2019 version supersedes the earlier 2009 edition and aligns with the broader EN 12390 series
Based on UKAS laboratory assessment reports and industry experience, here are the top non-conformities related to BS EN 12390-2:2019: bs en 12390-2:2019
The significance of this standard lies in its ability to ensure that concrete specimens are made and cured in a consistent and controlled manner, which is essential for obtaining reliable and accurate test results.

BS EN 12390-2:2019 (Testing hardened concrete – Part 2: Making and curing specimens for strength tests) is the European standard that governs this critical preparatory phase. It ensures that when concrete is tested in a laboratory, the results reflect the material's true potential, free from variables caused by poor handling.
Elias didn't move until he checked his stopwatch. He knew the 90-minute rule—if that concrete wasn't in the moulds soon, it was useless. He stepped into the light, carrying his steel moulds. These weren't just boxes; they were the "specimens" defined by the standard. Step 1: The Filling Cement content : The type and content of
After removal from the molds (demolding), the specimens must be cured in water or in a mist room. If water curing is used, the specimens must be fully submerged in a tank. The water temperature must be maintained at a constant 20°C (± 2°C). If a mist room is used, the relative humidity must be kept above 95%. This controlled environment ensures that the hydration of the cement continues optimally, allowing the concrete to gain strength at a predictable rate. Marking and Documentation
