ISO 527-4 Tensile Test Conditions for Fibre-Reinforced Plastic Composites

← Back to all standards

ISO 527-4 specifies the test conditions for the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites. To match this to your program, talk with our team.

What ISO 527-4 Covers

It applies the ISO 527 tensile framework to multidirectional and mat-based composites, fixing specimen and test conditions for these laminates.

How the Test Is Run

A tabbed composite coupon is pulled at a controlled rate with strain measured over the gauge length, and tensile strength and modulus are determined.

Why It Matters

Multidirectional composites are qualified against ISO 527-4; correct tabbing and strain measurement keep results comparable.
