we have a laboratory equipment's such as viscometer and we need to do an annual calibration to certify it , and i am wondering if the third party can do that and can the supplier certify with IS09001 AND IS017020\.
Calibration laboratories only certify to ISO 17025. As a testing laboratory, any equipment needing calibration must be calibrated by a competent laboratory that provides a calibration report that meets ISO 17025 clause 7.8.4 Specific requirements for calibration certificates. Typically such laboratories would be accredited. You would need the performance parameters of the device being calibrated and the metrological traceability of the calibration. i.e. the equipment used by the calibration lab has its own calibration and certificate traceable to national and or international standards / SI units. Furthermore, they need the expertise to provide you with the measurement of uncertainty of the measurements/performance of the equipment they calibrate for you.
