Abstract
PURPOSE: To make termination of sample easy and enable variation-free measurement to be performed without any hindrances such as chuck breakage and other by applying antislip treatment to the intermediate or outside twisted layer which constitutes the multilayer bare twisted wires.
CONSTITUTION: First, the multilayer bare twisted wires are cut to a requited length. Next, the outside and intermediate twisted wires 3, 2 on both sides are cut to let the core wires 1 of a suitable length protrude. The ends of the core wires 1 are bound with a vinyl tape 4. After the cutting, the outside and intermediate twisted wire layers 3, 2 are unravelled to a suitable length, i. e., the length corresponding to chuck mounting, after which glass powder or blast sand 5 is coated on the respective twisted wire layers 3, 2 by means of rapid cure type adhesives, double-coated tapes, etc. The intermediate twisted wire layer 2 and outside twisted wire layer 3 are wound in this order on the core wires 1 and are secured and bundled. The both end parts of the bundled outside twisted wire layer 3 and core wires 1 are again bound by means of a vinyl tape 4" or the like to form the chuck gripping parts A and this completes the preparation of the tension test sample.
