REFERENCE MATERIALS

 
       
The Institute for Interlaboratory Studies provides a limited number of Reference Materials (RM). The materials are very well characterised and of a high industrial relevance.
 
Production of Reference materials (RM)
The Institute for Interlaboratory Studies started preparation of Reference Materials in 1996 to aid its participants in their needs for additional proficiency support. The Reference Materials are certified on the basis of the results of an interlaboratory study. The materials are multipurpose and available in handy quantities. Certification reports are available for each RM and can be obtained from the Institute for Interlaboratory Studies.
All reference materials have a guaranteed shelf life. The Institute for Interlaboratory Studies regularly monitors the validity of the materials and after a positive evaluation the shelf life is extended and the corresponding certificate is updated.
Please note that the RMs are only available for participants in one or more of the iis PT schemes.
 
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 'reference values', in agreement with ISO Guide 34 and 35. Those parameters that could not be certified with the highest certainty, are still referred on the certificates, but as indicative values only.
