{{CIAAW2009}} adds a full reference (<ref>...</ref>) for the standard atomic weight (Ar, standard) of chemical elements as defined by IUPAC commission CIAAW (2009). The source is:
- "Atomic weights of the elements 2009 (IUPAC Technical Report)". Pure Appl. Chem. 83 (2): 359–396. 12 December 2010. doi:10.1351/PAC-REP-10-09-14.
 
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 updated values
  (This list:   )
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.
