How would I recognize an ITU-T standard if I saw one?

An ITU-T standard can be anything from a one-page document to one several hundred pages' long. Most ITU-T standards (Recommendations in ITU parlance) are available in electronic form, free of charge, here. The paper version of any Recommendation is published in A4 format. Electronic and print versions both carry the ITU logo and the designation ‘ITU-T Telecommunication Standardization Sector of ITU’.

Recommendations are divided into categories that are each identified by a single letter, referred to as the "series", and are numbered within each series. A Recommendation’s given name, when used as a reference, can thus be ‘H.323’ (H being the series, 323 being the particular Recommendation).
