ISO 1920-6 – Testing of Concrete: Sampling, Preparing and Testing Concrete Cores

  3. ISO 1920-6

ISO 1920-6 is Part 6 of the ISO 1920 series on testing of concrete. It specifies a method for taking cores from hardened concrete, examining them, preparing them for testing and determining their compressive strength.

The document does not give guidance on the decision to drill cores or on where to drill, and it does not give procedures for interpreting core strength results. ISO recommends that all parties reach full agreement on the need for core testing, and on how results will be interpreted, before any coring starts. Labs therefore confirm the coring plan and the acceptance basis with the client first, then handle examination, preparation and testing under this part.

Preparing cores for compression testing includes cutting them to the required length after drilling. Our CoreTrim 3000 core cutting machine is used for core preparation to support testing to ISO 1920-6. If you need help matching ISO 1920-6 requirements to your parts or setup, contact our team.
