While J-STD-001 specifies an upper limit for acceptance of assembly, we use Resistivity Of Solvent Extract testing as a process control. In truth, this "LT 10.07 �gm/sg in NaCl equivalent" measurement has substantial limitations, not the least of wh

There are no standards, nor should there be. Why would you want assess the quality requirements for an underhood product upon a company that makes talking furballs? We find that for the largest part, the approach taken by the rocket scientist that
