ISO 527-4Plastics -- Determination of tensile properties -- Part 4: Test conditions for isotropic and orthotropic fibre-reinforced plastic composites
ISO 527-4 determines the tensile properties of isotropic and orthotropic fibre reinforced plastic composite sheeting and film including the tensile strength and modulus of elasticity, strain, elongation and the tensile energy to break (TEB).
This test standard is equivalent to BS EN ISO 527-4:1997.
Before conducting ISO 527-4, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
