Development of New Standards for the Production and Use of Reference Materials

Angelique Botha, Inorganic Analysis, NMISA, Pretoria, South Africa (abotha@nmisa.org)

About two years ago, the ISO Technical Management Board took the decision to transform ISO/REMCO, the ISO Committee for Reference Materials, into a new technical committee - ISO/TC 334.  The main reason for this decision was to facilitate the transformation of the ISO/REMCO Guides, developed for the production and use of reference materials, into international standards.

At the first meeting of ISO/TC 334, the decision was taken to start from transformation of ISO Guides 30 to 35 as well as ISO Guide 80 into international standards through draft international standard (DIS)-ballots. This presentation will give an overview of the status of the development of the new ISO 33400 series of standards for the competent production and use of reference materials.
