This key comparison is part of the programme of the Gas Analysis Working Group (GAWG) of the CCQM to demonstrate the equivalence of the standards and measurement capabilities of the NMIs for greenhouse gases. ASTM/ISO 51539-05 (2013) Standard Guide for Use of Radiation-Sensitive Indicators. This report describes the results of a key comparison of standard gas mixtures of nitrous oxide in synthetic air at an amount fraction of 320 nmol/mol. ISO 9001:2015 PDF is completely free to download.Thanks very much for Lucy’s generous sharing.Part of the document is described as follows: The adoption of a quality management system is a strategic decision for an organization that can helpto improve its overall performance and provide a sound basis for sustainable development initiatives. In order to monitor levels of nitrous oxide in the atmosphere, it is necessary to use measurement standards with demonstrated equivalence at the highest level of accuracy.
