IUPAC kindly welcomes comments on its Provisional Recommendation "Guidelines for the use of atomic weights" by 31 Aug 2016.
Standard atomic weights are widely used in science, yet the uncertainties associated with these values are not well-understood. This recommendation provides guidance on the use of standard atomic weights and their uncertainties. Furthermore, methods are provided for calculating standard uncertainties of molecular weights of substances. Methods are also outlined to compute material-specific atomic weights whose associated uncertainty may be smaller than the uncertainty associated with the standard atomic weights.

Thanks for the reference.
The recommendation is very clear and easy to follow for anybody familiar with the GUM. Indeed, it provides me with interesting new examples for teaching UQ !
I found a few typos:

- page 9, Table 7, header: q0.925 should be q0.975
- page 12, line 19: missing table number (??-> 7)
