Primer on Engineering Standards
Description
Standards supplement the design process by guiding the designer toward consistency, safety, and reliability. As daily life involves increasingly complex and sophisticated instruments, standards become indispensable engineering tools to ensure user safety and product quality. Primer on Engineering Standards: Expanded Textbook Edition delves into standards creation and compliance to provide students and engineers with a comprehensive reference.
The different types of standards are dissected and discussed in terms of development, value, impact, interpretation, and compliance, and options are provided for situations where conformance is not possible. The process of standards creation is emphasized in terms of essential characteristics and common pitfalls to avoid, with detailed guidance on how, where, and with whom one may get involved in official development.
Organized for both quick reference and textbook study, this new Expanded Textbook Edition provides a quick, clear understanding of critical concepts, ramifications, and implications as it:
* Introduces the concepts, history, and classification of standards, rules, and regulations
* Discusses the federal, state, and local government's role in standards development and enforcement
* Distinguishes voluntary consensus standards, limited consensus standards, and jurisdictional versus non-jurisdictional government standards
* Covers the need for and process of exemptions to existing standards
* Examines the characteristics of a good standard, and discusses opportunities for involvement in development
* Includes case studies to demonstrate standards applications, and extensive appendices to direct further inquiry
The successful design, fabrication, and operation of any product relies on foundational understanding of pertinent standards; indeed, standards and guidelines form a central pillar of the engineering profession. This helpful resource goes beyond a list of rules to help students and practitioners gain a better understanding of the creation, import, and use of standards.
