ISO 899-1 is the test method for the tensile creep behaviour of plastics using standardized specimens. To match this to your program, talk with our team.
What ISO 899-1 Covers
It measures how a plastic slowly stretches under a constant tensile load over time, characterizing long-term tensile performance for design.
How the Test Is Run
A specimen is held under constant tensile load, usually at controlled temperature, and its extension is monitored over time to give the tensile creep and creep-rupture behaviour.
Why It Matters
Tensile creep data underpins long-term design of plastic parts under sustained tension; stable loading and accurate long-term strain measurement are essential.
