Titles
The word "standard" is a broad term that encompasses several types of standards that IEEE produces. There are really four categories of IEEE standards, each with a distinct meaning.

(1) Standards: documents with mandatory requirements
(2) Recommended practices: documents in which procedures and positions preferred by the IEEE are presented
(3) Guides: documents in which alternative approaches to good practice are suggested but no clear-cut recommendations are made
(4) Trial-Use documents: publications that are effective for not more than two years. They can be any of the categories of standards publications listed above.

When referencing an IEEE standard by its title, it is preferred that "IEEE" precedes the title. For example, IEEE Standard for Scheme Programming Language.

Numbers or Designations
IEEE standards are well-known and usually referenced by their numbers or numeric designations. When referencing standards in articles or news stories, it is preferred that the standard number is preceded with "IEEE Std" or "IEEE." For example, IEEE Std 802.11(TM) or IEEE 802.11(TM).

IEEE Logo
The IEEE provides guidance on the proper use of its logo and master brand. For more information, go to the Guidelines for Use of the IEEE Logo page.
