ISO 7743 is the test method for the compression stress-strain properties of vulcanized or thermoplastic rubber. To match this to your program, talk with our team.
What ISO 7743 Covers
It determines how rubber responds under compression, giving the stress at defined compression levels, used to characterize stiffness for mounts, seals, and bearings.
How the Test Is Run
A rubber specimen is compressed at a controlled rate between lubricated or bonded platens, and the stress at specified compression strains is recorded.
Why It Matters
Compression stress-strain defines rubber stiffness in service; a sensitive force frame and accurate deformation measurement are needed.
