What is ISO/IEC17025?

Its official name is “General requirements for the competence of testing and calibration laboratories.” In addition to the quality control like ISO9001, ISO/IEC17025 is an international standard which certifies the fulfillment of such “technical requirements” as tests, confirmation of appropriate calibration procedures, traceability, accuracy of the results, and reliability, as well as the capability to perform high-level tests and calibrations. The calibration data provided by the calibration organizations certified to ISO/IEC17025 are recognized as reliable internationally and guarantee calibrations at a high quality and technology level. The calibration results they provide include not only measurement results but also quality information such as “uncertainty” data of each measurement.


TOYO Corporation was certified to ISO14001, the most widely recognized international standard for environmental management, in September 2005. We strive to improve the environment continuously through environmental activities in compliance with ISO14001. Especially, we promote the environmental improvement activities globally by communicating our policy to the overseas principals we represent and by requesting their cooperation.
