No. Q-006 -- Independent Calibration of Test Equipment

Q : Is it an ISO 9000 requirement for a company to get independent body to calibrate
his test equipment ? 
A :  

The answer is NO.

ISO 9001 only requires a company to calibrate his equipment with traceability to
national or international standards. There is no requirement to get independent

A company can send his equipment out to any external laboratories (or
manufacturers) for performing calibration. On the other hand, test equipment can
also be calibrated in-house, provided the 'traceability' requirement is maintained.

One may find difficulty to determine which external laboratories to select. He/she
could check out the HOKLAS directory (which is issued by the Hong Kong
Government) to locate some laboratories that can help in calibration.
