Suitable Test Sizes for O-ring Specifications
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.
Currently limited to tensile tests though that is never explicitly stated anywhere in current 2-2007 version. This is causing confusion when referencing in AMS7xxx specs. ARP3050 needs to be revised to address not just tensile tests but also comp set and other tests
