ISO 18989 describes a procedure for generating tensile stress-strain curves for plastics, providing curve data for engineering use. To match this to your program, talk with our team.
What ISO 18989 Covers
It focuses on capturing full tensile stress-strain curves for plastics rather than single-point values, supporting design and simulation with continuous data.
How the Test Is Run
A specimen is pulled at a controlled rate with accurate strain measurement across the full range, and the complete stress-strain curve is recorded and presented.
Why It Matters
Full stress-strain curves feed material models and design work, going beyond the strength and modulus of a single-point report.
Reading the Designation
Cited as ISO 18989 with its edition year. Confirm the edition and specimen requirements before finalizing setup. To configure a plastics testing setup, request a quote.
Related Standards
ISO 527-1 gives the general tensile principles and ISO 17282 guides the acquisition of design data.
