Hi everyone,
I am comparing specifications revisions of MIL-C-15726 REV F (1988) to REV E (1965) and notice that the entire mention of any sort of bend testing has been removed in the REV F version. Can anyone shed any light as to why? My thought as to what the bend test was for is to make sure that the material being used is ductile and can withstand a bend without cracking. A visual inspection of cracks would be my guess of the acceptance criteria, however I can not find this. It points to FED-STD-151A Method 231.1 but I cannot seem to find a copy of this anywhere.
Liquid penetrant is mentioned in the spec as well. My thought is that the method wasn't as reliable as it is today in determining if a material has cracks in it. Is this perhaps why it was removed? That today's technologies catch this better than a simple bend and check with visual?
Any information is greatly appreciated. I need to know what replaces this test today.
Thanks
