I argue that the punch test is go-nogo, but there are those who argue that a
lab test may be required for marginal fabric. My answer is that "marginal"
is like being a little pregnant. IT passes or it doesn't.
It says NOTHING about how long the fabric will last. That is a function of
environment -- hangared or outside, humid or dry, hot or cold...
