The laboratory

ห้องปฏิบัติการสอบเทียบ

The laboratory of CG Engineering calibrates measuring and testing instruments for rubber and plastics, on site at your plant, to ISO/IEC 17025. It is staffed by trained personnel and works to standardised methods with standard equipment traceable to SI units, so results hold up metrologically.

The laboratory was first accredited to ISO/IEC 17025:1999 E (TIS 17025-2000) in 2004, under calibration certification number 0108. The certification was then renewed and updated to ISO/IEC 17025:2005 E on 9 March 2006.

The scope of certification of calibration methods gradually expanded. In 2016 certification number 0108 was withdrawn on relocation of the laboratory, and the lab was recertified to ISO/IEC 17025:2005 on 29 January 2016 by the Thai Industrial Standards Institute (TISI), under calibration certification number 0267.

The laboratory renewed the certificate to ISO/IEC 17025:2017 E (TIS 17025-2018) on 10 January 2019, and improves the quality of its calibration work continuously to serve a growing customer base — from around 15 customers at the beginning to 289 today.
