    Scope:

    The ASTM E251 standard defines test methods for the evaluation of a strain gauge’s performance characteristics. This standard includes testing equipment designs. Standard test methods E251 describes procedures for determining five strain gauge parameters:

    ParameterSection
    Resistance at a Reference Temperature8
    Gauge factor at a Reference Temperature9
    Temperature Coefficient of Gauge Factor10
    Transverse Sensitivity11
    Thermal Output12

    These test methods do not cover bonded resistance strain gauges used in transducers as sensing elements.

    Results:

    In ASTM E251, the results can be expressed numerically or graphically.

    The gauge factor is dimensionless and is expressed as follows,

    where:
    K = the gauge factor,
    R = the strain gauge’s resistance at test strain,
    Ro = the strain gauge’s resistance at zero or reference strain,
    L = the test structure length under the strain gauge at test strain,
    Lo = the test structure length under the strain gauge at zero or reference strain,
    ΔR = the change in the strain gauge’s resistance when strain is changed from zero (or reference strain to test strain),
    ε = the mechanical strain L-Lo / Lo.

    Conclusion:

    The ASTM E251 standard defines test methods for the evaluation of a strain gauge’s performance characteristics.
