There are standards for crimp type cable fittings derived from aircraft FAA standards where a failure of an aircraft control surface control cable would be lethal .
This involves pull tests at I think 4 x rated load and a special crimp tool that will not release unless driven home . There Is a lot of FAA literature on this .
I found out the hard way with X-ray equipment suspension cables full of “ certified assembly “ stickers that failed .
The vendor did not buy the FAA tools or test it .
I have no idea what Murray does , I bet he buys them . The vendor in my case were not honorable and did not do the tests . So I started testing myself — not just pull but shock loads by dropping a calculated impact big weight a certain distance to try to pull the end . Even after a lot of hassle , QC experts etc about 2%still failed , batches of 100 . You have to test , like FAA requires .
There are rated loads , rather low loads on our TF brake cable imho compared to size of it , but if a poor fit, wrong size cable wire r fitting it can almost fall off . Been there.
