Helper Apparatus - Penetration through most upper cowhides would be moderate on the off chance that they were simply put into contact with water without flexing, and the rate of entrance of most calfskins might be extraordinarily quickened by expanding the seriousness of the flexing (for instance, by expanding the sufficiency of the wrench movement on the test machine). Experience demonstrates that if a wide range of upper cowhide are flexed to a similar degree when tried on the machine, the water proofness of thick calfskins in genuine wear will be under evaluated, and that of thin cowhides over assessed. Consequently, the machine is constructed to the point that any of four amplitudes might be decided for specific tests. and The Auxiliary Apparatus is utilized for choosing whether a specific cowhide or gathering of calfskins ought to be flexed with 5, 7.5, 10 or 15% adequacy common lab types of gear producers.
