JCSS calibration service

JCSS calibration service of weight

We provide you with the standard of weight.

It's a weight to become the reference of scale which measures the weight. So the weight is required that the relation with national standard is specific. We provide you with JCSS calibration service of the weight which is required to ensure the traceability of weight and is optimum to construct the quality system.

• Our company is accepted by National Institute of Technology and Evaluation which is the qualifying activity that the technological capability calibrating the weight and traceability fulfill the reference of ISO/IEC17025 which is international standard approved by calibrating organization. So we can emit the calibration certificate with JCSS mark.
• This calibration certificate with JCSS mark is emitted by calibrating organization approved by IAJapan participating in MRA (international approval) of ILAC (International Laboratory Approval Cooperation organization) and APAC (Asia Pacific Accreditation Cooperation). This calibrating result is valid internationally and the traceability certification of the product measured by scale calibrated by weight with this certificate and exported becomes effective.
• JCSS calibration certificate becomes effective for "measurement standard which is traceable to the international or national measurement standard" under the direction of requirements 7.6 authenticated by ISO9001-monitoring hardware and measuring equipment.

＊The object which is over 1t becomes not more than M2 class.

Calibration room

It's possible to calibrate the weight with the range of 1mg to 2t which is highest level in Japan.

JCSS calibration service of scale

In order to ensure the reliability of the continuous data

We carry out the certification at the continuous data of customer's scale with JCSS weight.
The traceability of the customer's scale calibrated by JCSS with the weight which is traceable to international standard is ensured.
Our JCSS calibration subscribes MRA (International mutual approval) and is approved as the valid certificate internationally.

Calibration object : Electronic non-automatic scale
The calibration range : 5g to 50t
Scale interval : More than 0.1mg
The calibration method : Permanent establishment or on-site calibration
＊It needs that temperature coefficient is released for the specification of calibration object.

We also carry out JCSS calibration of other manufacturer's electronic balance, platform scale and truck scale.
We recommend "on-site calibration" which doesn't need transportation.

About JCSS

What is calibration company registration system (JCSS)?

• JCSS is the abbreviation for Japan Calibration Service System.
  The management of this organization starts as calibration company authorization system (it changed to calibration company registration system since 2005) based by the Measurement Law since November,1993 in order to ensure the traceability of measurement.
• This registration system needs to conform to requirements of the standard (ISO/IEC17025) about the calibration organization specified by International Organization for Standardization and International Electrotechnical Commission. It is the system to examine whether the quality system, the calibration method, the estimation of uncertainty and facilities of company are apposite for carrying out the calibration and the quality system is managed just as specified by documents examination and on-site review and to register it.
• The calibration company registered with JCSS can emit the calibration certificate with JCSS mark.
  And the calibration company which corresponds to international MRA can emit the calibration certificate with the following international MRA symbol.

Our company uses JIS Q 17025 (ISO/IEC17025) as accreditation criteria and is certified for the authorization scheme under JCSS managed according to ISO/IEC17011.
The qualifying activity (IAJapan) managing JCSS subscribes the mutual approval of Asia Pacific Accreditation Cooperation (APAC) and International Laboratory Approval Cooperation organization (ILAC).
Our mass standard center is the company certified by JCSS which corresponds to international MRA.
0212 is the approved number of our center.
