ISO 3386 describes a laboratory method for the compression stress-strain characteristics of low-density flexible cellular polymeric materials such as foams. To match this to your program, talk with our team.
What ISO 3386 Covers
It characterizes how a flexible foam responds under compression, giving the stress at defined strains, used to specify cushioning and comfort behaviour.
How the Test Is Run
A foam specimen is compressed at a controlled rate and the stress at specified compression levels is recorded, describing the stress-strain behaviour of the material.
Why It Matters
Compression stress-strain defines the firmness and cushioning of flexible foams; a sensitive low-force frame and accurate strain measurement are needed.
