BYK Instruments - Certification Services for Standards


Whether motivated by regulatory requirements or the need for assurance of correct and reliable measurements a regular certification of your working standards to a certified reference standard is critical to a manufacturing process according to ISO 9001 guidelines.

Our master standards for color and appearance are sent for recertification to international institutes on a routine basis as defined in our ISO 17025 guidelines. A clearly documented chain of calibration including master instruments to create working standards for production and local service standards controls the maintenance at all BYK-Gardner service points and authorized agents.
