ASTM A370 Test Fixtures & Test Systems Model: G-ASTM-A370-S14
Viscoelastic Creep: In polymer-lined piping, the hardness value will drop the longer the needle is held. Standardized Dwell Time is the only way to ensure lab-to-lab repeatability.
Type: Standards

Expert Commentary
Dwell Time: Always hold the durometer presser foot against the polymer for exactly 1 second before taking the reading. Plastics are viscoelastic; if you wait 5 seconds, the needle will creep downward, resulting in a hardness value that is lower than the ASTM standard requires.
