Conversion of Shore A to Shore OO
Conversion of Shore A to Shore OO
(OP)
Do the hardness scales Shore A and Shore OO overlap? If so is there a conversion chart available?

"...there may be no simple relationship between the results obtained with one type of durometer and those obtained with another type of durometer or other instruments for measuring hardness. This test method is an empirical test intended primarily for control purposes. No simple relationship is known to exist between indentation hardness determined by this method and any fundamental property of the material tested."
The equivalent 'DIN' standard is 'DIN 53505'.

Thank you for your valued responses.
Note that the scale conversion chart furnished by boo1 (March 30, 2003) turned out to be reasonably accurate, within the range I was interested. The material that I purchased with the advertised specification of 55-65 Shore OO was measured here with a Shore A durometer tester and achieved 15 - 20 Shore A. This fulfilled our immediate requirements. Thanks again.
