JEMIC calibrates the in-house standards and/or measuring instrument, including the reference standards for JCSS accredited laboratory, using the primary standards of accredited calibration laboratories and/or the reference standards according to the ISO/IEC 17025 requirement as the JCSS accredited calibration laboratory.
Whenever JEMIC carries out the accredited calibration, JEMIC issues the calibration certificate with JCSS marking. This calibration certificate guarantees the calibrated results by the measuring standard that is traceable to national standards.
The calibration certificate with JCSS mark meets the requirements of international regulations, like ISO/IEC 17025, ISO9000, ISO/TS 16949, QS-9000, etc.
JEMIC carries out the accredited calibration as the JCSS accredited calibration laboratory. Regarding the accepted field, see the following table.
