Bs En 12390-2:2019 -

The 2019 version replaced the older BS EN 12390-2:2009 standard. The updated version introduced stricter requirements regarding: Temperature verification during the initial curing phase.

The specimens must remain in the moulds for at least 16 hours, but no longer than 72 hours.

Accurate specimen preparation requires standardized tools. The standard specifies requirements for the following equipment:

The moulds must be in perfect condition, clean, and lightly oiled to prevent the concrete from sticking. The concrete sample is then re-mixed thoroughly on an impermeable surface to ensure uniformity before being placed into the mould. The standard specifies that the mould should be overfilled slightly to account for compaction. The amount of concrete used should be such that after compaction, a layer of concrete remains above the rim of the mould, ideally 10% to 20% of the specimen's height. This ensures a flat, flush final surface.

BS EN 12390-2:2019 is the current British and European standard for It replaces older versions (such as the 2009 edition) and aligns directly with modern European construction frameworks (EN 206).

Technical Overview: BS EN 12390-2:2019 BS EN 12390-2:2019 is a European standard adopted by the British Standards Institution (BSI) that specifies the methods for making and curing specimens for strength tests

Once cured, the specimens must be transported to the testing machine (such as a compression testing rig) with care to avoid any impact or damage that could compromise the test results.

Immediately after leveling, the specimens must be protected from moisture loss, wind, and direct sunlight. They are typically covered with a plastic sheet or lid.
