ISO 3386-1 — Compression stress/strain characteristics for low-density flexible cellular materials
ISO 3386-1 is the ISO method used to characterize how low-density flexible cellular polymeric materials behave under compression, giving the compression stress-strain response. To match this to your program, talk with our team.
What ISO 3386-1 Covers
It defines the procedure for the compression stress-strain characteristics of flexible foams, reporting the stress at specified compression levels for cushioning and comfort specification.
How the Test Is Run
A foam specimen is compressed at a controlled rate through defined strain levels, and the corresponding stresses are recorded to describe the material response.
Why It Matters
The compression stress-strain curve defines foam firmness and cushioning; a sensitive low-force frame and accurate strain measurement are essential.
