Initial efforts by workers at the Institute for Reference Materials and Measurement (IRMM), Geel, Belgium, to produce certified reference materials for GMOs have demonstrated that the provision of suitable reference materials is not easy and that together with the development of suitable analytical methods there are many challenges to be solved ahead. The first two examples produced jointly by the IRMM in Belgium and Fluka Chemie AG in Switzerland were based on Round-Up Ready Soya and BT 176 Maize. The reference materials are needed to validate EU and Swiss regulations which permit non-GMO products to be contaminated by up to 1 % GMO material and still be accepted.

Some reference material producers/suppliers use different names to describe their materials. For example, a Standard Reference Material (SRM) is a certified reference material issued by the National Institute of Standards and Technology (NIST), while European Reference Materials (ERMs) are CRMs produced under a joint collaboration between three European reference materials producers, i.e. BAM (Federal Institute for Materials Research and Testing, Germany), IRMM (European Commission, Joint Research Centre, Institute for Reference Materials and Measurements, Belgium) and LGC (UK). 

A limited selection of environmental reference materials is also available from the European Institute for Reference Materials and Measurements in Belgium http // www.irmm.jrc.be/... 

For application in the isotope dilution technique and for tracer experiments using isotope enriched spikes, Merck (Darmstadt, Germany) have launched the production of new sets of isotopically enriched materials, such as 53Cr or mCd enriched spike calibration solutions, which were characterized by the Institute for Reference Materials and Measurements (IRMM, Geel, Belgium).52... 

One problem is the availability of reliable reference materials for isotope ratio measurements. Certified isotope standard reference materials are available from NIST (National Institute of Standard Reference Materials, http //www.nist.gov/srd/, formerly NBS - National Bureau of Standards) and IRMM (Institute for Reference Materials and Measurements, http //www.irmm.jrc.de). There are isotope standard reference materials for light elements (H, Li, , C, N, O), Mg (magnesium metal isotopic standard NIST SRM 980), and for moderately heavy elements such as (potassium chloride isotopic standard NIST SRM 985), Cr (chromium metal isotopic standard NIST...

Systems of classification very often follow the application fields, e.g. the catalogues of the Institute for Reference Materials and Measurements (IRMM), the National Institute for Standards and Technology (NIST), Laboratory of the Government Chemist (LGC), etc. or the database for certified reference materials COMAR.
