Introduction
LGC’s Science and Technology Division acts as the designated UK National Measurement Institute (NMI) for
Chemical and Biochemical measurement and has a long history in the development and validation of
analytical methods and the production of reference materials.
Many of the analytical methods used to characterise the reference materials are accredited to ISO/IEC 17025
(Requirements for the competency of testing and calibration laboratories) and have been verified through
participation on key comparison studies organised by the Consultative Committee for the Amount of
Substance (CCQM) of the International Weights and Measures Organisation (BIPM). The reference material
production is accredited to ISO Guide 34 (General Requirements for the competence of reference materials
producers) and the certificates are recognised by other National Measurement Institutes, under the Mutual
Recognition Arrangement.
LGC is a founder member of the European Reference Material (ERM
®
) co-operation established in 2004,
along with the Institute for Reference Materials and Measurement (IRMM) in Belgium and Bundesanstalt für
Materialforschung und Prüfung (BAM) in Germany. ERM
®
members are committed to using the most
advanced principles for the production of certified reference materials; providing certified values with clearly
defined and stated traceability; and providing transparency of their approaches for the production of certified
reference materials. Details of the ERM
®
concept, policy and guidelines can be found on the ERM website
www.erm-crm.org.
In its role as the NMI, LGC serves on the International Organisation for Standardisation (ISO) Committee for
Reference Materials (REMCO), which aims to carry out and encourage a broad international effort for the
harmonization, production and application of certified reference materials (CRMs).
Full details of LGC’s accreditation schedule can be found on the UKAS website (www.ukas.com).
To purchase any of the reference materials listed and described in this catalogue, please contact LGC
Standards (www.lgcstandards.com).
