IEEE 494

Description / Abstract: This document establishes criteria for the uniform identification of documents significant to design, construction, testing, operation, and maintenance of Class 1E equipment and systems for nuclear power generating stations. It includes recommendations for identification of specific parts of these documents. Criteria are also established for identification on documents of redundant portions of Class 1E equipment and systems. The quality assurance program, as applied to Class 1E equipment procurement, should provide records sufficient to meet the needs and requirements of IEEE Std 279-1971, Criteria for Protection Systems for Nuclear Power Generating Stations (ANSI N42.7-1972), and IEEE Std 308-1974, Standard Criteria for Class 1E Power Systems for Nuclear Power Generating Stations. Additional identification on procurement documents is, therefore, not required.

2. Purpose

The purpose of this document is to provide a method for identification of documents relating to Class 1E equipment and systems such that users of the documents will be able to recognize those systems which must meet the requirements set forth in IEEE Std 279- 1971 (ANSI N42.7-1972) and IEEE Std 308- 1974.
