The process begins with obtaining a representative sample of fresh concrete according to EN 12309-1. Once the sample is ready, the molds are prepared by applying a thin film of non-reactive release agent to the internal surfaces.

The 2019 revision introduced several technical updates to align with modern practices and improve consistency: bs en 12390-2:2019

BS EN 12390-2:2019 is a critical standard for testing hardened concrete in the construction industry. By following the testing procedures outlined in this standard, construction companies can ensure that their concrete products meet the required compressive strength specifications. Compliance with BS EN 12390-2:2019 provides numerous benefits, including improved quality control, increased confidence, and compliance with regulatory requirements. As a result, it is essential for construction professionals to understand and implement the testing procedures outlined in BS EN 12390-2:2019 to ensure the structural integrity and durability of concrete structures. The process begins with obtaining a representative sample

The standard mandates that moulds must be rigid, non-absorbent, and capable of retaining their shape. It provides precise dimensional tolerances (e.g., for 150 mm cubes, the tolerance is typically ±0.2 mm) and specifies that the internal surfaces must be smooth and free from defects. A significant emphasis is placed on the verification of mould dimensions, recognizing that worn or warped moulds produce non-standard specimens that yield inaccurate strengths. By following the testing procedures outlined in this

Before a single specimen is made, the laboratory or site technician must ensure that all equipment conforms to the tolerances defined in and its companion standard BS EN 12390-1 (shape and dimensions of moulds).

In the construction industry, the compressive strength of concrete is the primary metric for structural quality. However, the accuracy of this metric relies heavily on consistency. How a concrete sample is treated between the time it is cast and the time it is tested can drastically alter the results.
