Bs En 12390-2:2019 ★ Real

Adherence to BS EN 12390-2:2019 is vital for structural integrity and legal compliance.

Under ISO/IEC 17025 (laboratory accreditation), simply following the standard is not enough – you must prove you followed it.

BS EN 12390-2:2019 implicitly (and sometimes explicitly) requires the following records: bs en 12390-2:2019

Many laboratories are now using digital barcode tracking linked to temperature sensors to automate compliance with the 2019 version.

✅ Before casting: Verify mould calibration and cleanliness.
✅ During filling: Use appropriate compaction method for slump class.
✅ After casting: Cover immediately; record time.
✅ Storage before demoulding: Maintain 20°C ± 5°C; protect from vibration.
✅ Demoulding: At 24 h ± 2 h; mark clearly; check for defects.
✅ Curing: Use lime-saturated water at 20°C ± 1°C (or ±2°C). Log continuously.
✅ Transport to test lab: Keep protected and avoid temperature shock.
✅ Documentation: Keep all logs for at least 10 years (as per project records). Adherence to BS EN 12390-2:2019 is vital for

By following BS EN 12390-2:2019 meticulously, you ensure that the compressive strength result reflects the concrete – not the mistakes of the technician. That is the essence of standardized testing.

Testing hardened concrete — Part 2: Making and curing specimens for strength tests

This is used to assess whether the concrete delivered to site meets the specified strength requirements. The specimens are cured under idealized, standardized conditions (temperature and humidity) to eliminate external variables. The goal is to test the potential quality of the concrete mix, not the actual in-situ strength.
