No. See Q241 in the Q&A - "Working Pressure is not Proof Pressure."

EDIT: While I've been frustrated over the years with the alternative reality English dictionaries that only the GDC has access to, I agree with their position on this. Proof pressure is usually a multiplier applied to working pressure, but there doesn't appear to be consensus on what that multiplier is.
