ISO 14125:1998
Fibre-reinforced plastic composites — Determination of flexural properties
ISO 14125 is a test method to determine flexure properties of fiber-reinforced plastic composites. There are two methods used, Method A for a three-point flexure test and Method B for a four-point flexure test. There are four material classes, Class I – IV, which define the specimen length, span, width, and thickness. The standard requires deflection measurement not exceed +/- 1% error of full scale. The 2810-400 bend fixture is fully compliant with these requirements.
The challenges of testing to this standard:
Flexural strain measurement
Repeatability of calculations
Reporting calculations in compliance with the standard
