EN 12504-1 — Testing Concrete in Structures (Cored Specimens)

← Back to all standards

EN 12504-1 is the European Standard for taking, examining, and compressive-strength testing of drilled concrete cores. To match this to your program, talk with our team.

What EN 12504-1 Covers

It defines a standardized approach for extracting cores from an existing structure or precast element and determining their compressive strength.

How the Test Is Run

A drilled core is examined, trimmed, and loaded in compression, and the compressive strength is calculated from the failure load and dimensions.

Why It Matters

Core compressive strength verifies in-place concrete; high-force compression capacity and correct end preparation are essential.
