TABLE 4-2 

 Inspection and Proof Tests of Wire Rope Shots 

 (26-29 June 1968) 



Procedure 



1. Measure swaged fitting diameters for proper dimensions before 

 and after swaging. 



2. Apply reference mark to cable near swage termination. 



3. Conduct the following tension proof tests for 10 minutes 

 on each shot: 



a. B-3540 wire rope shots to 7000 lbs. 



b. B-3695 wire rope shots to 12, 000 lbs. 



4. Measure length of each shot at 50% and 25% of proof load after 

 successful completion of proof load test. 



5. After completion of proof test inspect location of reference mark 

 for evidence of pull-out from swaged termination. 



6. X-ray and Zyglo all terminations and examine for evidence of 

 damage or faults. 



7. Complete molding of boots over terminations. 



Results 



1. All shots completed procedure successfully. 



2. Elastic stretch of wire rope: 



a. B-3540: 1. 16 x lo'^ ft. /ft. -lb. 



b. B-3695: 0.585 xio' ft. /ft. -lb. 



3. Measured lengths given elsewhere in this report.
