ASTM D7912-14 Resistance of Finish to Heat Aging

ASTM D7912-14 Resistance of Finish to Heat Aging

ASTM D7912-14 test method determines whether a leather finish is resistant to cracking, flaking, or turning sticky after ageing. The standard values are reported in the SI unit.


    ASTM D7912-14 test procedure is useful for a variety of finished leathers. Finish stability is also important in founding the application and function of leather.


    The finish is visually evaluated after the test specimen has been exposed to prolonged heating and then flexed manually in this test procedure.

    Specimen size:

    The temperature should be 55 to 60 °C. The suggested sample size of leather is 10 cm2


    Changes in stress-strain properties are calculated as, 

    P =A -O÷O×100


    P = percentage change in property

    O = original value

    A = value after aging
