VS SPL - Vodja Standardizacije za splošno področje

IWA 5:2006 is the result of discussions at a workshop on emergency preparedness held in Florence, Italy, 24-26 April 2006.
It presents the consensus of the workshop participants in the form of the workshop recommendations.
It provides recommendations and guidance to ISO/TC 223 as the first step in a process that may eventually lead to the development of international standards on this subject.  
It provides the reader with some additional resources for further exploration of this area which is crucial to all organizations and entities.

ISO Guide 35:2006 gives statistical principles to assist in the understanding and development of valid methods to assign values to properties of a reference material, including the evaluation of their associated uncertainty, and establish their metrological traceability. Reference materials (RMs) that undergo all steps described in ISO Guide 35:2006 are usually accompanied by a certificate and called a certified reference material (CRM). This Guide will be useful in establishing the full potential of CRMs as aids to ensure the comparability, accuracy and compatibility of measurement results on a national or international scale.
In order to be comparable across borders and over time, measurements need be traceable to appropriate and stated references. CRMs play a key role in implementing the concept of traceability of measurement results in chemistry, biology and physics among other sciences dealing with materials and/or samples. Laboratories use these CRMs as readily accessible measurement standards to establish traceability of their measurement results to international standards. The property values carried by a CRM can be made traceable to SI units or other internationally agreed units during production. ISO Guide 35:2006 explains how methods can be developed that will lead to well established property values, which are made traceable to appropriate stated references. It covers a very wide range of materials (matrices), ranging from gas mixtures to biological materials, and a very wide range of properties, ranging from chemical composition to physical and immunoassay properties.
