BAM is the Federal Institute for Materials Research and Testing of Germany. BAM aims to improve safety in technology and chemistry through research and development, testing, analysis, approvals, advice and information. Within these interconnected fields important areas are the collaboration in developing statutory regulations, for example on safety standards and threshold values or the development and supply of reference materials and methods, in particular for chemical analysis and materials testing. Furthermore, BAM assists in the development of standards and technical regulations for the evaluation of substances, materials, structures and processes.

Members of BAM’s “Materials and Air Pollutants” division have many years of experience in measurement and the definition of standards and protocols for testing VOC emissions from building products. Several round robin tests were organised to check the test chamber method for VOC emissions. BAM is involved in the European and national standardisation for emission testing of building products and indoor air relevant emitting compounds. In the EMRP JRP ENV01 MACPoll (Metrology for Air Chemical Pollutants) BAM worked on the development of a constant emitting material based on a lacquer system as carrier material. In this JRP it is planned to continue the work by creating a candidate reference material on the basis of a VOC emitting polymer which shall be used for quality assurance and quality control purposes in materials emissions testing. BAM will lead WP3 and participate in WP4.

LNE is committed to excellence in measurement and testing and to progress in quality and safety, for the benefit of industries and consumers alike. Since 1997, LNE's public mission has been specified in a fulfilment agreement drawn up every four years with the French government. The state's financial contribution takes the form of annual subsidies. These enable LNE: to operate as the national reference laboratory in metrology for French industry - to pursue its scientific and technological development in order to anticipate new measurement and testing requirements created by advances in technology and society's new expectations in the spheres of safety, health, quality and environmental protection - to provide state authorities and key economic players with the technical assistance they require to draft new regulations and standards at national, European and international level, develop new test methods and carry out market surveillance.

Applying its multidisciplinary technical expertise, LNE provides companies with services in the fields of metrology, medical and health products, construction products, packaging, transport, environment and industrial products. LNE offers a full range of technical conformity services, from calibration and testing to technical assistance and training. LNE is also a certification body, providing companies with the technical solutions they need to ensure the quality and conformity of their products and enhance them on markets worldwide.

LNE will contribute to this JRP in the following fields: preparation of gravimetric and dynamic gas mixtures and analysis of gas mixtures (WP1,WP2 and WP4). LNE develops and maintains Reference Materials, which are primary standard gas mixtures obtained by using gravimetry as a preparation technique. The gravimetric principle, which is described in the International Standard ISO 6142, is a powerful tool to produce accurate gas standards. LNE also has specialised experience in environmental measurements. It plays a central role in the French Central Laboratory for monitoring air quality (LCSQA), which ensures the technical coordination of the monitoring networks in ambient air. LNE has also developed capabilities in gas analysis and is fully accredited to ISO/IEC 17025 standard.



METAS, the Swiss Federal Institute of Metrology, is the Swiss NMI. It realises and disseminates internationally harmonised and recognised measurement standards at the required accuracy. The Analytical Chemistry Section provides services related to the application of measuring instruments in the fields of environment and health, and it provides standards and calibration services to measure air pollutants.

The Gas Analysis Laboratory at METAS has provided services in the area of gaseous airborne pollutants and carries out accurate measurements for gas mixtures for over 25 years. It started with the analysis and homologation of exhaust gas analysers according to Swiss national law. A special emphasis of the laboratory lies on the dynamic generation of gas mixtures. The participation in CCQM-K74 has already proven the low uncertainty of the primary dynamic generation system based on magnetic suspension balances. METAS is very strong in accurate gas flow calibrations as proven in EURAMET project 806 and has also already participated in a number of EURAMET and CCQM projects and key comparisons. For this reason, METAS will contribute to WP2 and WP4 activities in this JRP, with the generation of dynamic gas mixture standards for OVOCs and terpenes at concentrations below 100 nmol/mol. This will combine the experience of permeation and dilution methods with highest purity matrix gases for a very low concentration range.



The National Physical Laboratory (NPL) is the National Measurement Institute for the UK and is a world-leading centre of excellence in developing and applying the most accurate measurement standards to science and technology.

NPL also holds a leading position in the preparation and analysis of standards required for atmospheric and air quality monitoring. NPL disseminates a full suite of standard gas mixtures to support the EU Air Quality Directives; which are based on a combination of standards prepared by gravimetric dilution and dynamic dilution methods. Additionally, NPL has developed a suite of standards for VOCs. These were initially developed to meet the requirements for the EU Ozone Directive, but they have now been extended to form the basis for the WMO/GAW Primary Standard for the global monitoring of eight priority hydrocarbons.

NPL will lead WP2 and participate to WP1 and WP4.
