Try ISO/CD 27895-Vacuum technology -- Test procedure for valves.

   This might be of help to your requirement.

The standard API and EN valve standards does not address it.

There used to be a Shell SPE addressing this. But it is now not listed in the current version.

I found these threads at eng-tips,
