JCSS (Japan Calibration Service System)


1. JCSS (Japan Calibration Service System)

jcss

JCSS (Japan Calibration Service System) is the system to assess whether calibration laboratories meet the requirements of the standards related to calibration laboratories provided by the International Organization for Standardization and the International Electrotechnical Commission (ISO / IEC 17025), and accredit them.
As an JCSS accredited laboratory of pH standard solution, metal standard solution, ion standard solution and organic standard solution (volatile organic compound), Wako supports the reliability of a variety of the results of tests and calibrations from the foundation by ensuring the traceability of reliable measurement to national measurement standards.
We have been accredited as an international MRA accredited testing laboratory by IAJapan (International Accreditation Japan) , a member of MRA (Mutual Recognition Agreement) with ILAC (International Laboratory Accreditation Conference) and APLAC (Asia Pacific Laboratory Accreditation Cooperation) , and have issued the calibration certificates with JCSS accreditation symbol with the ILAC and MRA as its proof. These valued results with the description of JCSS certificates are internationally acceptable through MRA with ILAC and APLAC.

* We conform to ISO Guide 34: 2009 and ISO / IEC 17025: 2005 (JIS Q17025: 2005) as a calibration laboratory and a standard material producer. (The accreditation of standard material producers is not conducted by ILAC and MRA.)
