ASTM D2990 is the set of test methods for how plastics deform over time under a constant load, covering tensile, compressive, and flexural creep. To match this to your program, talk with our team.
What ASTM D2990 Covers
It measures the slow, time-dependent deformation of plastics under sustained load, essential for parts that must hold shape under long-term stress.
How the Test Is Run
A specimen is held under constant load in tension, compression, or flexure, often at controlled temperature, and its deformation is recorded over time to give creep and creep-rupture behaviour.
Why It Matters
Creep governs long-term dimensional stability of plastic parts; stable long-duration loading and accurate deformation measurement are required.
