| REFERENCE MATERIALSThe Institute provides a limited number of Reference Materials (RM). The materials
are very well characterised and of a high industrial relevance.

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 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.
The certificates available through this web site are for information only and are not the valid certificates.
All reference materials have a guaranteed shelf life.
The Institute regularly monitors the validity of the materials and after a positive evaluation the shelf life is extended
and the corresponding certificate is updated.
However, it has to noted that the RMs are only available for participants in one of the iis PT schemes.
