NOTE: Hardness values are +/- 5 points on the Shore 'A' scale, and +/-2 points on the the 'D' scale. All other values are +/-10%. These values are not to be used for specification purposes. They are only to serve as a guide for engineering and application design. | |||
Freudenberg-NOK makes no claims as to the accuracy or variance of test results.
We emphasize that this tabulation should be used as a guide only. It is based primarily on laboratory and service tests,
but does not take into account all variables that can be encountered in actual service conditions before specification.
If this is not practical, tests should be devised that simulate service conditions as closely as possible.
