Application Summary AI generated

This standard specifies the test method for determining the sensitivity coefficient (k-factor) of electrical resistance strain in metallic materials. It is applied in materials testing laboratories and quality control settings to evaluate how a metal's electrical resistance changes under mechanical strain, which is critical for designing strain gauges and stress analysis in structural engineering. The standard is primarily used for metal sheets, wires, and foils in industries such as aerospace, automotive, and civil infrastructure.
