TaiBoWei Industrial Co.,Ltd. Calibration System Description

The TaiBoWei Industrial Co.,Ltd. calibration system is maintained by QA Inspection and its management.

The overall purpose of the system is to control the accuracy of measuring and test equipment (M&TE) and measurement standards used to insure that supplies and services delivered to the customer comply with prescribed technical requirements.

M&TE employed by TaiBoWei Industrial Co.,Ltd. are selected to possess the accuracy, stability, range and resolution required for their intended use.

TaiBoWei Industrial Co.,Ltd. subcontracts all Calibration functions to suppliers of calibration services which:

•     Provide traceability to acceptable national standards. Perform calibrations in controlled environments consistent with functions calibrated.

•    Perform calibrations by procedures which suppliers are willing to release to TaiBoWei Industrial Co.,Ltd..

•    Notify TaiBoWei Industrial Co.,Ltd. of out-of-tolerance and other conditions encountered upon suppliers receipt of the M%TE

•    Provide certificates, reports or data sheets contracted for.

•    Provide decals on items calibrated including source, date of calibration and projected recalibration due date.

TaiBoWei Industrial Co.,Ltd. performs the following functions to maintain controlled accuracies of the M&TE:

•    Submits to calibration service suppliers at regular intervals to maintain M&TE. The basic interval is every two years, unless an extension is documented.

•    Maintains records of calibration actions for each item of M&TE.

•    Performs reviews of in and out-of-tolerance conditions of calibrated M&TE to determine the reliability of each item of M&TE and the appropriate actions for correcting potential hardware deficiencies arising from use of significantly out-of-tolerance items.

•    Adjusts calibration intervals on the basis of individual item reliability. Items experiencing out-of-tolerance conditions three (3) straight recalibrations will have their current calibration interval halved. Items experiencing in-tolerance conditions three (3) straight recalibrations may have their current calibration interval doubled.
