Punch test?

The punch-test gives an approximation of the tensile strength of the
fabric. It has nothing to do with how long the fabric will last.

That is the absolute truth. The condom is only so strong from manufacture;
how many times can you use it before it breaks catastrophically?




The fact a 20 year old covering measures high-green on a strength test
is no guarantee the thing won't fall apart next week. There could be
corrosion, dry-rot or rampant rusting going on under that slick,
always-hangared fabric skin.


Which was not the question. The question was the fabric itself. The
remainder of the airframe is quite another matter.
