1. OCTOBER 26th, 2005 GAS METROLOGY WORKSHOP

2. TOPICS Gas Reference Materials in Mexico Reference Materials in INFRA-Air Products Industry Acreditation Status Regulatory Organisms MESURA poject INFRA-CENAM

3. Gas Reference Materials in Mexico In Mexico there´s exist Primary Standards related to the industry applications produced by CENAM. This is because according to Regulations (LFMyN), only the primary Lab (CENAM) is the organism authorized to produce those Primary Standards in México.

4. Gas Reference Materials in Mexico Those standards are not good enough to supply the main Industry requirements So, The main requirement is that gas producers be authorized to produce Gas Reference Materials

5. Gas Reference Materials in Mexico That would be based on ISO Guide 30, 31, 34 and ISO/IEC- 17025 as it was discussed in last meeting with Regulatory Organisms

6. Gas Reference Materials in Mexico To date EMA CENAM and DGN are looking for an agreement to develope a policy regarding the production of Gas Reference Materials by Gas Producers

7. Organisms REGULATIONS TECHNICAL BASIS ADMINISTRATIVE SYSTEM

8. Reference Materials in INFRA-Air Products As a corporate strategy, INFRA as a part of Air Products and Chemicals Europe, we are developing an integartion plan for the Reference Standards Production in both blending and analitycal areas: Fix Sources Movile Sources Natural Gas

9. Reference Materials in INFRA-Air Products To Date, INFRA uses Gas Standards certified and validated by CENAM and DGN: Foreign Standard (NIST) INFRA Standard (CENAM)

10. Reference Materials in INFRA-Air Products MRP MRC MRTC SRM NTRM GMIS CENAM NIST

11. Industry Acreditation Status Day by day, our customers are getting the acreditation from EMA (Entidad Mexicana de Acreditación). They require to have Gas Reference Standards in order to calibrate and adjust their process or lab equipment

12. Industry Acreditation Status Products we deliver to our customers has to be adressed and approved in DGN (Dirección General de Normas) and CENAM (Centro Nacional de Metrología) With the above approval, then the product can be considered as a Reference Material

13. Regulatory Organisms ORGANISMS - NIST(Instituto Nacional de Estandares y Tecnología) - DGN(Dirección General de Normas) - EMA (Entidad Mexicana de Acreditación - CENAM (Centro Nacional de Metrología)

14. MESURA PROGRAM INFRA-CENAM INFRA & CENAM are in a process to work in a program to produce Gas Reference Materials (MRTC). This program considers production and analytical areas in order to have the whole control for the reference materials produced

15. PROGRAMA MESURA
