I have a copy of Rubber Manufacturer's Association O-ring inspection guide from 1986.
I don't think this is published anymore but I have not been able to find anything that may have superceded it.

anyone know? I'm thinking and SAE document maybe as SAE was involved in writing the acceptance limits for the book I have.

What I found was MIL-STD-413 C. See this handbook from Dichtomatik.

That might be a handy manual - thanks.

I was lead to beleive the RMA manual superceded MIL-STD-413.
The cross-references between the various standards are very useful.

You're welcome, and you may be right about RMA manual. I actually had a hard time finding anything useful that could be shared.

I believe that this (THE RMA RUBBER HANDBOOK ™ FOR MOLDED, EXTRUDED, LATHE CUT AND CELLULAR PRODUCTS, 6th edition, 2005) is the replacement manual. O-rings would fall under the molded category. I have used this manual in the past for a variety of different molded rubber products.

MIL-STD-413C is the most detailed inspection guide I know of, and it's in the public domain. The RMA guide for O-ring surface imperfections has been discontinued. MIL-STD-413 has been active for a very long time. The RMA published the RMA Guide and they coexisted for several years. Actually the RMA guide has two categories, A and B. Category A is the same as MIL-STD-413. Category B is a bit more lenient. It was probably the intent of the RMA to introduce a less stringent requirement for less critical applications.

AS871 is an SAE document for Aerospace O-rings.

AS708 is an SAE document for Top Visual Quality O-rings (good luck getting a quote).

ISO 3601-3 has three grades, commercial (kind of like RMA category B), aerospace (like AS871) and critical service (like AS708).

I believe that AS871 and MIL-STD-413 will be canceled in the next few years and ISO3601-3 will be adopted, but who knows how long it will take?

The RMA handbook for molded products mentioned above will not suffice for O-rings.
