UL817 Cable Testing Equipment Abrupt Pull Test Apparatus With 6 Working Stations
UL817:
96.4 Each molded-on representative device is to be secured in the jaws of the flexing machine so that the point of cord exit is at the center of rotation. The rotating jaws are to be adjusted to rotate to an angle of 90° to each side of the centered position. At the centered position, the cord is to hang vertically and the weight, selected in accordance with 96.3, attached to each cord approximately 1 2 inches (305 mm) from the point of rotation. See Figure 96.1 .
96.5 Each representative device is to be subjected to complete flexing cycles until a conductor in each device has opened (as determined by a continuously-monitoring detection circuit), or until 2,500 cycles is reached, whichever comes first. A flexing cycle consists of: rotation of the jaws from the vertical (centered) position until 90° to one side, back past the vertical position until 90° to the other side, and back to the vertical (centered) position. The rate of testing shall be 1 0 cycles per minute.
