want to know information about
works/projects which have industrial impact.
procedures for conducting peer review.
new methods and new techniques.
how to establish dissemination services and traceability.
technical supports
to reduce type B uncertainty in the Circular-T.
for frequency calibration services.
on time transfer receiver’s calibration.
joint cooperation, joint research, bilateral/multilateral comparisons.
financial supports for a peer review assessment.
standard documents (procedures) on calibrations and uncertainty evaluations.

4. Possible Technical Supports for Developing Economies
Possible Supports
A*STAR Training on T&F metrology, calibration on frequency standard,
counter, timer and stopwatches.
