  • Brief introduction of Calibration Laboratory

    Calibration Laboratory of Apparatus and Instrument, Xuchang KETOP Electrical Research Institute (originally called Calibration Laboratory of Apparatus and Instrument, Xuchang Relay Institute, hereinafter referred to as “Calibration Lab”)is a third-party calibration agency approved by CNAS (China National Accreditation Service for Conformity Assessment) and a linked unit of the twenty-first Machinery Industry Measurement and Testing Center Station (Xuchang) .
    Under the guidance of the Certification & Accreditation Administration of the P.R.China and the China Machinery Industry Federation, the calibration Lab always adheres to the service concept of "speed, smile and help customers to succeed", and devotes itself to studying the frontier calibration technology and calibration methods and providing authoritative calibration programs and calibration services for Apparatus and Instrument and electric power test equipment in the Electro-technical field.
    While continuously developing its business, the calibration Lab actively absorbs the advanced management ideologies at home and abroad to improve the strategic management infrastructure of the Calibration Lab, and continuously improve the management system of the Calibration Lab according to the needs of the market so as to enhance the market competitiveness. After years of development and accumulation, calibration laboratories already have good social resources and technical strength, and have great industry influence both in China and in the world. We have the following industry public resources:
    (1) Three National Quality Testing Centers:

    • National Center for Quality Supervision & Testing of Relay Protection and Automation Equipment
    • National Center for Quality Supervision & Testing of Smart Micro-grid Control Equipment and System
    • National Center for Quality Supervision & Testing of Electric Vehicle Charging and Battery Swap System

    (2) Industry Organization Resources:

    • Two National Metrology Calibration Institutions:

    Calibration Laboratory of Apparatus and Instrument, Xuchang KETOP Electrical Research Institute;
    Twenty-first Machinery Industry Measurement and Testing Center Station (Xuchang);

    • Two National Academic Organization:

    Professional Committee of China Electro-technical Society (CES) on Electric Power System Control & Protection;
    Professional Committee of China Electro-technical Society (CES) on Electric Vehicle Charging and Battery Swap System;

    • One National Industry Association:Branch of China Electrical Equipment Industry Association (CEEIA) on Relay Protection & Automation Devices
    • One National Standard Committee: Technical Committee of Standard Administration of China on Measuring Relays and Protection Equipment (SAC/TC 154)
    • One Chinese Core Journal: Protection & Control of Electric Power System

      • In October 2003, the calibration Lab was approved by China Machinery Industry Federation and the Twenty-first Machinery Industry Measurement and Testing Center Station (Xuchang) was established.
  • Impartiality Commitments

    In order to ensure the Impartiality of Calibration Lab. Calibration Lab makes the following commitment:
    1. Our business do not accept any intervention from outside or other administrative institutions, which may have an impact on work quality. And the Calibration results do not accept any intervention from both internal and external staff.
    2. We would abide by constitutional laws and regulations, engaged in Calibrating within the scope of the recognized ability in a legitimate, just and fair manner.
    3. Calibration Lab and its staff shall not have any interest relationship with Calibrating activities, issued data and results they engage in; Shall not engage in any activity which may damage independence and integrity of the Calibrating.
    4. Calibration Lab and its staff shall not affected by any pressure from both internal and external unjustifiable commercial 、financial or other aspects that may affect the quality of work.. In the meantime, Calibration Lab and its staff shall prevent commercial bribery.
    5. We pledge to abide by CNAS-CL01 Testing and Calibration Lab Accreditation Standards and Laboratory accreditation criteria, and continuously improve the management system.
    6. With the service concept "speed, smile, help customers to succeed", we are dedicated to provide our customers with services of supreme quality and high efficiency to meet their needs.
    7. We would meet the demands that come from general statutory authority or organizations which provide recognition for Calibration Lab .
    8. Keep the customers' technical and non-technical secrets which are known during the calibration, all levels of personnel in Calibration Lab shall strictly abide by the regulation of the confidentiality and protection of ownership to protect customers’ confidential information and proprietary rights.

    Calibration Lab will strictly abide by the commitment above, and we are open to accept supervision from all sectors of the community.
