Dear all

More than 20 years have passed since we started our series of inter-comparisons including the production of consensus values for the reference materials, w= hich archive has been widely used within the community. We are aware of th= e continuing widespread use of the reference materials from TIRI, FIRI and VIRI. It seems that this would be a timely juncture to review the consensus values, especially since some were based on a relatively small se= t of measurements and so may be less robust.

We would therefore like to instigate a review of the consensus values for as m= any of the reference materials as possible. We would then present an upda= ted set of values at the next ¹⁴C conference in Paris.

Would you be willing to sending an Excel sheet of your results? As always w= e will retain laboratory anonymity, this exercise is purely to investigate whether evidence exists for updating the consensus values and their uncertainties.

Timescale

To allow time for re-analysis, t= he data sets would need to be sent by the end of October 2011. We would undertake the review and the evaluation sent back by May 2012 to all those = who sent results, with a view to presenting the findings at Paris (with due acknowledgement of all those who have participated). Please email the data in Excel sheets with the sample identifier clearly marked to marian.scott@glasgow.ac.uk <= o:p>

thank you

Hi David, I hope you will be able to help, but very br= iefly and explained in more detail in the attachment, I am planning to review the sets of consensus values for TIRI, FIRI and VIRI materials that are in widespread use, and am contact folks to ask for their help, first in provid= ing data, and then once I have repeated and refined calculations, to review.I h= ope to get this completed in time for the Paris meeting.

best wishes and I look forward to hearing from you.
