DESCRIPTION:
Auxiliary Apparatus
Auxiliary Apparatus - Penetration through most upper leathers would be very slow if they were merely put into contact with water without flexing, and the rate of penetration of most leathers may be greatly accelerated by increasing the severity of the flexing (for example, by increasing the amplitude of the crank motion on the test machine).
Experience shows that if all types of upper leather are flexed to the same extent when tested on the machine, the water proofness of thick leathers in actual wear will be under estimated, and that of thin leathers over estimated.
For this reason, the machine is so constructed that any one of four amplitudes may be chosen for particular tests.
The Auxiliary Apparatus is used for deciding whether a particular leather or group of leathers should be flexed with 5, 7.5, 10 or 15% amplitude.
