Metrology in Chemistry (MIC) has become an important field in recent years to assure traceability of chemical measurements within the conformity assessment of free trade agreements. The development of a reliable national MIC system represents especially for developing economies a great challenge. The Asia Pacific Metrology Programme (APMP) has developed together with PTB’s International Technical Cooperation a special approach to be implemented through its committees for Developing Economies (DEC) and Metrology in Chemistry (TCQM) for such National Metrology Institutes (NMI), which just started with chemical measurements and need orientation. The basic concept consists of the elaboration of a generalized roadmap and a series of participative workshops to accompany the implementation steps with a group of selected developing NMI’s. The different experiences, mainly related to economic strength, political strategies and proper initiatives, were used to adjust the programme and open it for other interested NMI’s by defining now specific home works and case studies related to export problems or regulation enforcement. In the actual stage, case studies of common interest as for pesticide residues in tea or heavy metals in fish were selected. Participating NMI’s are analyzing the specific situation in their economy regarding the type of contamination and the availability of reliable measurements in the value chain (from tealeaf to teabag). They identify related testing facilities and their traceability to link them through their NMI to the APMP and to an NMI with related CMC’s in the BIPM KCDB. Additionally, an interregional exchange between APMP and SIM was stimulated. Similar programmes in both organisations will lead to a larger pool of experiences that can be shared and serve as reference for NMI’s starting to develop their MIC system. First conclusions: The “Guide to Creating or Improving a National Infrastructure for Chemical Measurement“ is available on APMP website. Developing NMI’s have learnt the complexity of setting up the system and that the first step starts with a profound analysis of needs, supply and gaps in chemical measurements. Concrete case studies help identifying priorities as well as collaboration between NMI’s and on the regional level.
