ISO 178 Flexural Properties of Plastics (3-Point Bending)
ISO 178 is the test method for the flexural properties of rigid and semi-rigid plastics using three-point loading. To match this to your program, talk with our team.
What ISO 178 Covers
It determines flexural strength and modulus of plastics, aligned with the international framework, for material selection and quality control.
How the Test Is Run
A bar specimen is supported near its ends and loaded at the center at a controlled rate, and flexural strength and modulus are calculated from the load-deflection curve.
Why It Matters
Flexural properties are a core plastics metric; a rigid three-point fixture and accurate deflection measurement keep results comparable.
