A major use of ISO 4 is to abbreviate the names of scientific journals using the LTWA. For instance, under ISO 4 standards, the Journal of Biological Chemistry is cited as J. Biol. Chem., and the Journal of Polymer Science Part A should be cited as J. Polym. Sci. A (capitalization is not specified by the standard). The standard notes that "Full ...
