Overview
SIST EN 12390-1:2021 is a comprehensive European standard published by CEN that specifies the shape, dimensions, and tolerances for hardened concrete test specimens and their moulds. This document is critical in ensuring reliable and repeatable testing results for concrete by standardizing the physical parameters of test specimens such as cubes, cylinders, and prisms, as well as the moulds used to produce them.
The standard replaces the earlier EN 12390-1:2012 and includes updated tolerances that align with current industry practices. It facilitates conformity in strength testing and other property assessments of hardened concrete, providing clear guidelines for specimen preparation.
Key Topics
Specimen Types
- Cubes: Nominal sizes range between 100 mm and 300 mm, with declared sizes allowed within ±10% of nominal.
- Cylinders: Diameters range from 100 mm to 300 mm, height typically twice the diameter.
- Prisms: Widths from 70 mm to 300 mm, with lengths at least twice the width.
Dimensional Tolerances
- Flatness, perpendicularity, and straightness tolerances are rigorously defined, for example:
- Cube face flatness tolerance: 0.0006 × designated size.
- Cylinder diameter tolerance: ±1%.
- Prisms require perpendicularity within 0.5 mm relative to the base.
- Flatness, perpendicularity, and straightness tolerances are rigorously defined, for example:
Measurement Procedures
- Specimens must be measured unless produced in calibrated moulds.
- Certified calibrated moulds follow stricter tolerances, allowing reduced specimen measurement needs.
Mould Requirements
- Moulds must be watertight, non-absorbent, and robust enough to prevent distortion.
- Calibrated moulds are typically made from steel or cast iron.
- Flatness and perpendicularity tolerances are specified for mould surfaces, aiding accurate specimen formation.
Conformance with Geometrical Standards
- References EN ISO 1101 for geometrical product specifications, emphasizing flatness, perpendicularity, and straightness.
- Annexes provide detailed methods for assessing flatness and applying tolerance requirements.
Applications
Concrete Material Testing
- Ensuring standardized specimen dimensions improves accuracy and repeatability of compressive strength tests, flexural strength tests, tensile splitting strength tests, and other property evaluations.
Quality Control in Construction
- Concrete producers and testing labs use this standard to verify specimen conformity, assuring the quality and performance of concrete batches used in structural engineering projects.
Research & Development
- Laboratories developing new concrete formulations rely on these tolerances and specimen specifications to validate mechanical properties under controlled conditions.
Calibrated Mould Manufacturing
- Mold manufacturers design products meeting EN 12390-1 standards to support concrete testing labs in producing compliant specimens.
