Fibre-reinforced plastic composites. Determination of the mode II fracture resistance for unidirectionally reinforced materials using the calibrated end-loaded split (C-ELS) test and an effective crack length approach1 Scope This International Standard specifies a method for the determination of mode II shear load delamination resistance. GIIC, (critical energy release rate), of unidirectional fibre reinforced plastic composites using the calibrated end loaded split (C ELS) test. It is applicable to carbon fibre and glass fibre reinforced thermosets and thermoplastics. The scope is not necessarily limited to these fibres and lay ups, but for laminates with other

voltage adjustment tappings

This also specifies the environmental test methods for potentiometers
