ISO 18872: Plastics — Tensile properties at high strain rates

← Back to all standards

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.
