What developing economies need
• Access to free market– For survival– For economic development
• Mutual recognition– In testing results– Equivalence in measurement value
• Metrological traceability – Easy access– Reasonable cost

Developing NMIs’ wishes
• Stability of national metrology system– Stable SI units– Stable metrological traceability chains– Long term use of measurement standards
• Expansion of measurement capabilities– Wider ranges → more applications
• Accessibility to measurement standards and calibration services

Developing NMIs’ wishes
• Improvement of measurement accuracy– Better medical diagnosis– Higher quality and safety– Better control and prevention
• Affordable metrological traceability to SI base units– Realisation of primary measurement standards– Realisation of SI base units

Metrological Traceability: NIMT
• Mass metrology:– National Kilogram Prototype No. P80 (kg)– Mass standards classes E0 and E1– Vacuum mass comparator
• Thermometry:– Triple point of water (K)– Primary and secondary fixed point– Standard Platinum Resistance Thermometers

Metrological Traceability: NIMT
• Electrical metrology:– Josephson voltage standard (V)– Quantum Hall resistance standard (Ω)– Zener diodes & DMMs– Thomas One Ohm resistors & Bridges
• Chemical metrology:– Traceable to mol & kg

Questions
• Will these red measurement standards be calibrated against new primary realisation of SI base units?– When will be first opportunities?– How expensive will they be?– How long will they take?– How good will their measurement uncertainty be?

Questions
• Will developing NMIs ever be able to achieve primary realisation of the SI base units at home? (Option only for rich and developed NMIs??)– NIMT has no solid plan to do this at the moment– Will this affect research in metrology and HR
development in developing economies?

Questions
• How will Key Comparisons be affected by the new primary realisation of the SI base units?– Will future list of key comparisons be dominated
by comparisons between these primary realisations?

General comments & concerns
• New definitions will increase reproducibility and stability to the SI units– SI base units will be realised with higher accuracy– Lead to new technologies, applications and products
• National metrology system will be disturbed– National measurement standards need new metrological
traceability to SI base units
• Measures to support developing NMIs– Ensure accessibility to metrological traceability to SI base units– Availabilities with acceptable cost for developing NMIs
