The German Federal Institute for Materials Research and Testing

The German Federal Institute for Materials Research and Testing (BAM) draws upon more than 100 years of tradition developing reference materials to support correct and reliable measurements.

These reference materials are useful for determining measurement uncertainty, calibration, validation of methods, and for suitability testing and quality assurance.

BAM is accredited by the Deutsche Akkreditierungsstelle (DAkkS) as a producer of reference materials (RM and CRM) in accordance with ISO 17034 (General requirements for the competence of reference material producers). The reference materials are certified in accordance with the principles and requirements of ISO 17034 and ISO Guide 35.
