The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.

The data confirm the literature reports that Type M hardness measurements on O-rings are usually higher than Type A on disks/buttons/plied platens, but the difference decreases as the O-ring cross section increases. Though the permitted Type A hardness range for fluorocarbons conforming to AMS7276 is 70–80, actual commercial production is overwhelmingly at the high end of this range and …
