A licensed professional engineer in Austin, Texas, Hunter has been engaged with these issues for over a quarter century, either as a company employee or as a consultant. Standards are discussed often, he says, but the other three measures rarely come up in polite conversation, though they have been defined and redefined in a new set of international standards by the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC). Bundling the four more tightly than is usual, he presents an overview of them at the international, regional, national, provincial/state, and company levels. His account should interest not only engineers, he says, but also people involved in regulatory compliance. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
