EN 826 — Determination of Compression Behaviour (Thermal Insulation Products)
EN 826 is the European test method for the compression behaviour of thermal insulating products used in building applications. To match this to your program, talk with our team.
What EN 826 Covers
It determines the compressive strength or stress at a defined deformation for thermal insulation boards such as foams and mineral wool, supporting product classification and building use.
How the Test Is Run
An insulation specimen is compressed between platens at a controlled rate, and the compressive stress at a specified relative deformation, or at failure, is recorded.
Why It Matters
Compression behaviour governs where an insulation product can be used under load; a suitable low-force frame and accurate deformation measurement are needed.
