John, I can only try to relate safety with the extensive use of "shall" with ISO certification having gone through the lead auditor course nightmare.
For ISO 9001, there's about 136 "shalls" listed. Get all your "shalls" right and you *will get* the certification. Miss a "shall" and you *will get* most likely what's called a "major". Just one major and you could lose your certification. In order to keep the certification (pass inspections), one MUST have a compliant system in place. That being said, "shall" IMO indicates something inevitable in the future as in something to do. "Must", also IMO, indicates something inevitable in the present as in something one must have now. In some respects, this is used in standards when one goes for agency testing, such as construction and performance. Once you've passed the "shalls", you move into the "musts" since having passed the shalls you now obviously must have something compliant. Man, that sounds too much like legalize. Think I'll go soak my head ... Regards, Doug At 04:07 PM 7/16/99 -0400, John Juhasz wrote: >>>> Hi group. The subject here is regarding the words 'shall' vs. 'must' in various of product safety standards (including UL 1950 3rd Ed. and EN60950). Does anyone have any insight into the definitions of these as applicable to product safety? I have heard there are differences, but no one can seem to give me an answer. Comments please. John A.
