EA, today and tomorrow

This article presents the European co-operation for Accreditation (EA) as it is to day and tries to focus on the main goals on which we will be challenged in the very near future.     

The Applicaton of IAF Theory to the Study of Dissociation Equilibrium (Ⅱ) --The Calculation of Solubility Product Constant in Nonaqueous Solvents

This article reports a theoretical calculation of solubility product constant of several slightly soluble silver salts in a number of nonaqueous solvents according to the IAF (interaction force) theory based on the interaction free energy of electrostatic, orientation, induction and dispersion. The calculated values of pKsp are in good accordance with those from literature.     

How to approach membership of IAF/ILAC Arrangements: the peer evaluation system of IAF and ILAC for single accreditation bodies

Peer evaluation is used by the international accreditation organisations IAF and ILAC as a tool to harmonise the results of accreditation of conformity assessment bodies and as a control mechanism to ensure constantly competent services according to harmonized standards. Upon positive evaluation outcome, the accreditation body may join an Arrangement (MLA/MRA) between accreditation bodies, confirming systematic reliability and competence to the market. The objective of these Arrangements is that they will cover all accreditation bodies in all countries in the world, thus eliminating the need for suppliers of products or services to be certified in each country where they sell their products or services. This article is to aid single accreditation bodies wishing to sign these Arrangements in the future, and, furthermore, to communicate the procedure and the relevance of evaluation to the public in order to build up confidence in such Arrangements.
