((CIAAW2011)) adds a full reference (<ref>...</ref>) for the standard atomic weight (Ar, standard) of chemical elements as defined by IUPAC commission CIAAW (2011). The source is:
"Atomic weights of the elements 2011 (IUPAC Technical Report)". Pure Appl. Chem. 85 (5): 1047–1078. 29 April 2013. doi:10.1351/PAC-REP-13-03-02.
This template has options to use by refname, and as plain source (no <ref> tag). See #Options.
Notes
CIAAW publishes changes in the atomic weights biannually, nominally in uneven years.

)CIAAW may publish changes to atomic weights (including its precision and derived values). Since 1947, any update this is done in odd years nominally; the actual date of publication may be some time later.
These references will appear in the article, but this list appears only on this page.
