BS EN 12390-2:2019 defines strict, standardized procedures for making and curing hardened concrete specimens to ensure accurate, consistent strength test results. It mandates specific guidelines for mould preparation, compaction methods, and environmental controls for specimens during initial and final curing stages. For more details, visit BSI Knowledge

Without adherence to BS EN 12390-2:2019, a concrete strength test result is not legally valid under most European and UK construction contracts. bs en 12390-2:2019

BS EN 12390-2:2019 specifies methods for making and curing concrete specimens for strength tests. It applies to concrete sampled in the field or produced in a laboratory. | | BS EN 12350-4 | Fresh concrete

This standard applies to concrete tested under laboratory conditions, specifically for:

: Standardizing preparation ensures that variations in test results are due to the concrete mix itself, not how the specimen was handled.

Concrete samples must be obtained following EN 12350-1 and thoroughly remixed before use. Molds are typically filled in multiple layers depending on the concrete's consistency; however, self-compacting concrete is filled in a single layer without additional vibration. Compaction
