ABRASION RESISTANCE
1. SCOPE
1.1 This method is intended for use in determining the abrasion resistant characteristics of the finished
wire or cable.
NOTE: Intended for use with neoprene cable.
2. SPECIMEN
2.1 This specimen shall consist of 2 samples of finished insulated wire or cable. Each sample shall be
30 inches in length, minimum.
3. APPARATUS
3.1 The apparatus shall be as follows:
3.1.1 Abrasion tests (see figure 1).
4. PROCEDURE
4.1 Tow untested samples 30 inches in length, shall be mounted securely at one end and weights, as
specified in table I, freely suspended to the other end with the cable or wire placed over a squirrel cage
abrasion tester as shown on figure 1. A suitable tripping circuit shall be arranged to denote failure by
stopping the machine when any bar of the squirrel cage come in contact with the bare conductor of the
cable or wire. The specimen shall be subjected to 20 + 2 oscillations per minute. An oscillation shall
consist of 5 bars travel forward and backward from a given point.
