BS EN 12390-2:2019 the British and European standard that defines the procedures for making and curing concrete specimens for strength tests

Significant changes vs. 2009 edition

• Editorial revisions and harmonization with EN 12350‑1 for common apparatus/specification.
• Clarifications regarding equivalence of compaction methods and caution on internal vibrators with air‑entrained concrete.
• Recognition that controlled humidity curing can be equivalent to water curing.

a) Curing for the Purpose of Quality Control (Standard Curing)

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. bs en 12390-2:2019

Demolding: Careful removal is required to avoid edge damage, which can weaken the specimen during a compression test. 4. Final Curing Conditions BS EN 12390-2:2019 the British and European standard
