Certipur® Certified Reference Materials: Now with ISO Guide 34 Accreditation.

Certified reference materials (CRMs) are standards used to verify the quality and traceability of products. In analytical laboratories, these standards are required for calibration and qualification of analytical instruments. Of course, the reliability of the instruments and their results are highly dependent on the accuracy of the reference materials used.

To help you work with absolute confidence, Merck’s Certipur® certified reference materials offer premium quality as well as comprehensive international accreditations – which now also include ISO Guide 34. These essential certifications, combined with Merck’s analytical and production expertise, help ensure the certainty of your analytical measurements.

Our Latest Seal of Approval: ISO Guide 34

ISO Guide 34 accreditation confirms Merck’s competence as a reference material producer. Developed and published by the ISO (International Organization for Standardization), ISO Guide 34 describes a set of stringent requirements that ensure all aspects of the production of Certipur® reference materials are carried out with measurable and traceable quality. The Guide’s comprehensive requirements cover production planning, material selection, assignment of certified values, uncertainty, traceability, homogeneity and stability, as well as packaging and documentation.

Multiple Accreditations for Maximum Security

While ISO Guide 34 ensures the high quality of Certipur® reference materials, it is founded on several underlying certifications already granted to Merck. Among these is our ISO/IEC 17025 accreditation, which also confirms our competence as a testing and calibration laboratory. The diagram depicts the relation between our multiple certifications, and how they lead up to ISO Guide 34 approval.

ISO Guide 34: Accreditation as a reference material producer
ISO Guide 35: Outlines principles for calculating the uncertainty of the certified value
ISO Guide 31: Describes the contents of the certificate of analysis and accompanying documentation
ISO Guide 30: Confirms that standards are characterized according to CRM definition
ISO/IEC 17025: Accreditation as a testing and calibration laboratory
ISO 9001: Defines requirements for quality management systems
