As an Auditor I always asked for proof of calibration for all scales - now, this could come in the of "official" documents such as state or county requirements (I remember Cook County, IL had this requirement that every year a specific company did all the calibrations and issued certificates) as as documented in-house calibration records - all I was interested in was proof.
Auditors should keep their mouths shut when it comes to making statements - always follow your GFSI Scheme, county, state, province, etc requirements and have proof of calibrations - there is no fall back to say that so and so told you verbally that you did not have to do so. In my eyes as an Auditor if you can not come up with either something in writting that you don't have to do this or records or certificates that you do it's the same as not being done.
As Dick Fisher from my Howard Johnson and Howard Johnson's franchise inspection days said - Verbal Don't Go!
Also, if TOP management told you this - they need to back their mouths up with documented proof - you don't want to get hung out to dry.
