We are going to begin using the sealing wax in-house next month for thread gauges. The gauges will be sealed and returned to service locations and will then be checked for seal damage when the next interval comes around. If the seal is damaged the calibration will be done on the gauge. If the seal integrity remains we will extend the calibration based on last calibration in our system and return the gauge to service. If the gauge comes up for calibration in two cycles and the seal still remains intact we will remove the gauge from service. We currently have 3,4,6 and 12 month intervals on these gauges due to use and wear based on locations.
Our ISO auditor only scratches the surface during an audit when doing the calibration section. With the case stated above set for implementation next month, is it necessary to revise our calibration interval section in our ISO 9001.
