ISO 844 is the test method for the compression performance of rigid cellular plastics (rigid polymer foams). To match this to your program, talk with our team.
What ISO 844 Covers
It determines the compressive strength and behaviour of rigid foams used for insulation and structural cores, based on their cellular response to load.
How the Test Is Run
A foam specimen is compressed between platens at a controlled rate, and the compressive strength, typically at a specified deformation, is recorded.
Why It Matters
Compressive performance defines where rigid foams can be used under load; a low-to-moderate force frame with accurate deformation measurement is required.
