Tutorial: How to Install a Strain Gauge Sensor on Glass X

One of the oldest ASTM (American Society for Testing and Materials) committees, Committee C14 on Glass and Glass Products develops test standards for determining the mechanical properties of all types of glasses, including ceramics.
ASTM C158 (Standard Test Methods for Strength of Glass by Flexure) provides test methodology for determining the modulus of rupture. The primary challenge using strain gage sensors on glass is surface preparation, which must be done carefully so as not to disturb the glass surface and alter strain readings.
