ASTM D1621 is the test method for the compressive properties of rigid cellular plastics (rigid foams). To match this to your program, talk with our team.
What ASTM D1621 Covers
It determines the compressive strength and modulus of rigid foams such as insulation and structural foam, materials that carry load through their cellular structure.
How the Test Is Run
A foam specimen is compressed between platens at a controlled rate, and the compressive strength, usually at a defined deformation, and modulus are recorded.
Why It Matters
Compressive strength governs the load-bearing use of rigid foams; a suitable low-to-moderate force frame and accurate deformation measurement are needed.
