ISO 18872 describes procedures for determining the tensile properties of moulding and extrusion plastics. To match this to your program, talk with our team.
What ISO 18872 Covers
It provides a tensile-testing approach for moulded and extruded plastics, aligned with the ISO 527 framework, to obtain comparable strength, modulus, and elongation data.
How the Test Is Run
A specimen is pulled at a controlled speed with strain measured over the gauge length, and the tensile properties are determined from the stress-strain curve.
Why It Matters
Consistent tensile data supports material selection and quality control for moulding and extrusion grades.
