REFERENCE MATERIALS

The Institute provides Reference Materials (RM's) for laboratory QA programs (internal, ISO 900x, ISO 17025). The materials are very well characterised and of a high industrial relevance.

The production of Reference materials (RM's) by I.I.S.

The Institute for Interlaboratory Studies started preparation of Reference Materials in 1996. The Reference Materials are certified on the basis of the results of one or more interlaboratory studies. The materials are multipurpose and available in handy quantities. Certification reports are available for each RM and can be obtained from the Institute.

All reference materials have a guaranteed shelf life. The Institute regularly monitors the validity of the materials and informs the registered users accordingly.

Multipurpose materials

The reference materials can be used for various test parameters, since they were validated for more than one parameter. In principal the materials have been tested according to common commercial specifications.

The parameters that could be certified with the highest certainty are indicated on the certificate as 'certified'. Those parameters that could not be certified with the highest certainty, are still referred on the certificates, but as indicative values.
