A documented process manages records of calibration and verification. Such records are kept for every gauge and every piece of measuring and test equipment needed to show conformity to internal, legal, regulatory and customer requirements, including equipment owned by employees, by the customer or by suppliers working on site. The activities and records cover: revisions made after engineering changes that affect measurement systems; readings found outside specification when equipment is received for calibration or verification; an assessment of what risk that condition poses to the intended use of the product; when equipment turns out to be faulty or no longer in calibration, a judgement on whether earlier measurements remain valid, with the standard's most recent calibration date and when it is next due; telling the customer if suspect product has been shipped; statements of conformity once calibration or verification is done; confirmation of the software version used for controlling product and process; and records of calibration and maintenance, and of verification of production-related software, for all gauging.
