Holiday Test - Artificial Pinhole

Hi, I'm Woo and a newbie here.

I'm trying to find out what the diameter should it be for the artificial pinhole(s) in a calibration of Holiday Test.

I've refered to ASTM G62-87 Standard Test Methods for Holiday Detection in Pipeline Coatings (Reapproved 1992) and it's not stated there.

Anyone, please reply. Thanks!
