To evaluate physical and mechanical properties of Lapp cable to insure that these products retain critical qualification values of impactt resistance when exposed to a free-fall force. These tests are performed to verify compliance with Lapp Mechanical Resistance Cable Attributes, Industry Tests and Safety Agency Standards.
Finished cable samples are marked at specified intervals along the jacket surface to identify impact points. For free-fall impact testing both the jacket and insulation of each specimen is stripped and the conductors are connected in parallel. A current source is connected to the exposed paralleled conductors. Visual devices are used to identify any short circuit condition that occurs while under impact, this process is repeated several times. The test is completed once all points long the specimen have been impacted with the specified weight without the occurrence of a short circuit condition. Test results are compared to standard requirements electronically to avoid potential error and insure accuracy.
