Is there a "standard" method for determinimg the initial recall date for a new device? We receive many new devices with manufacturer's calibration certificates, some specify the date the manufacturer performed the calibration, others don't. If there's no date specified we typically determine the recall date from the date the device is placed in service plus the calibration interval. If the certificate does specify a date, do we use the manufacturer's calibration date plus the interval or use the date placed in service plus the interval? In some cases the manufacturer's calibration date plus the interval would still leave the calibration expired. Does the device need to be recalibrated before placing it in service? It's just been sitting on someone's shelf waiting to be sold. Is the calibration really no longer valid?
