BS EN 12390-4:2019

What is BS EN 12390‑4 - Testing hardened concrete about? 

BS EN 12390‑4 is the fourth part of the multi-series standard that discusses the testing of hardened concrete. Hardened concrete is the strongest and most durable construction material. 

BS EN 12390‑4 specifies the requirements for the performance of compression testing for the measurement of the compressive strength of concrete. 

Who is BS EN 12390‑4 - Testing hardened concrete for? 

BS EN 12390‑4 on compressive strength with the specification for testing machines for testing hardened concrete is applicable for: 

• Manufacturing of concrete material 
• Civil Engineers 
• Contractors 
• Quality testing personnel 

Why should you use BS EN 12390‑4 - Testing hardened concrete? 

The requirements for testing machines set out in BS EN 12390‑4 have been formulated to satisfy the need for those compressive tests on concrete specimens. 

BS EN 12390‑4 gives you the concern of the ability to accurately determine the failure load of small or low strength specimens. It also concerns that the ball-seating fitted to the upper platen can be too large to align satisfactorily on the top of such small specimens and special adaptations can be required. 

BS EN 12390‑4 provides you with the details of testing machines for testing hardened concrete such as its specification, the installation and connection and maintenance. Using BS EN 12390‑4 you can understand the performance of compression testing for the measurement of the compressive strength of concrete. 

What’s changed since the last update? 

BS EN 12390‑4:2019 supersedes BS EN 12390‑4:2000, which is withdrawn. It includes: 

• The text is aligned with EN ISO 7500‑1 to avoid duplication 
• Machines to be Class 1 except those manufactured before 2000 where Class 2 is acceptable 
• Increase in verification points and new limits of acceptance over the working range 
• Description of verification procedure for strain gauge column 
• Deletion of Annex B.
