Great care must be taken when removing the moulds. If the concrete is damaged during this process, the specimen is compromised. Once demoulded, the specimens should be marked clearly and permanently.
The 2019 revision superseded the 2009 version. While the core principles remained consistent, the update introduced several refinements to align with modern practices and improve quality assurance:
Under ISO/IEC 17025 (laboratory accreditation), simply following the standard is not enough – you must prove you followed it. bs en 12390-2:2019
BS EN 12390-2:2019 implicitly (and sometimes explicitly) requires the following records:
Many laboratories are now using digital barcode tracking linked to temperature sensors to automate compliance with the 2019 version. Great care must be taken when removing the moulds
The standard distinguishes between two curing phases:
A. Initial Curing (In Molds)
B. Subsequent Curing (After Demolding)
This is the most operationally critical section of the standard. Many laboratories are now using digital barcode tracking
