There are many tests that have been developed to characterize rubber O-rings. Many of these tests are independent of the size of the O-ring being tested. However, there are some tests, specifically, stress/strain properties, that are a function of the O-ring’s size. The purpose of this report is to provide guidelines for specifying O-rings that would be considered “suitable for testing” when writing O-ring material specifications.
This specification covers established metric (SI) manufacturing tolerances applicable to non-cellular rubber products ordered to metric dimensions. These tolerances apply to all conditions, unless otherwise noted. The term "exclusive" applies only to the higher figure of the specified range.
