METHOD OF TESTING WEAR RESISTANCE OF WIRE COVERING MATERIAL

摘要

A method of testing wear resistance of a wire coating material includes (a) preparing a wire coating material as a specimen; and (b) relatively moving a wear member with respect to the specimen in a state where the wear member is in contact with the specimen. A first value associated with a relative movement amount of the wear member with respect to the specimen is obtained. A second value associated with a wear amount of the specimen is obtained. A value that evaluates wear resistance is calculated by dividing the first value by the second value. The wear resistance of the wire coating material is evaluated based on a degree of the value.
