IEEE 270-2006 PDF

This standard includes definitions for physical quantities and units commonly used in applied science and technology, and related terms that concern systems of measurement. Particular emphasis is placed on the International System of Units (SI). IEEE Std 270-1966 attempted to cover not only quantities and units, but also the much broader area implied in its title, "General (Fundamental and Derived) Electrical and Electronics Terms." This scope proved to be far too broad, and the standard could not be maintained. The purpose of this revision is to present authoritative definitions of physical quantities and units and other terms relating to measurement systems, with particular emphasis on the vocabulary used in IEEE/ASTM SI 10. Revision Standard - Inactive-Reserved. The definitions for physical quantities and units commonly used in applied science and technology, and for related terms that concern systems of measurement, are included in this standard. Particular emphasis is placed on the International System of Units (Le Systeme International d'Unites, SI).
