3. Why Do We Need Codes and Standards? To ensure quality For standardization of product design, manufacture, testing, and operation SAFETY

4. What products and industries are covered? Planes, trains, and automobiles Fasteners Computers, TVs Building construction Medical Devices Cranes Boilers and pressure vessels Elevators Fire protection systems/equipment The list goes on…

5. Key Terminology Specification Procedure Standard Regulation Code

6. Specification Definition: A detailed description of how to produce something or how to perform a specific task.

7. Specification Example A design specification for a coal feeder will specify physical size constraints, desired volumetric feed rate, belt speed, available power supply, etc.

8. Procedure Definition: A series of tasks that must be performed to produce a desired outcome.

9. Standard Definition: 1) Artifact that serves as a basis for comparison; a reference against which other things can be evaluated or calibrated.

10. National Institute of Standards and Technology (NIST) Established in 1901 Originally the National Bureau of Standards (name changed in 1988) Measurement standards laboratory Official mission: – “Promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve quality of life.” www.time.gov – official U.S. time www.time.gov – Contributes to world time called Coordinated Universal Time (UTC)

11. Standard Definition: 2) A set of technical definitions and guidelines that function as instructions for designers, manufacturers, operators, or users of equipment. Also called a standard specification

12. Standard Specification Requires the agreement of a group of individuals or an organization Intended to improve the consistency of manufactured materials and processes resulting in more uniform results

13. Standard Example ASTM International (formerly American Society for Testing and Materials) ASTM A577/A577M – Standard Specification for Ultrasonic Angle-Beam Examination of Steel Plates – 3-page standard costs $33 – Complete 82-volume set of 2010 ASTM standards includes over 12,000 standards and costs $9691

14. Regulation Definition: A principle, rule, or law designed to control or govern behavior.

15. Code Definition: 1)A systematic collection of regulations and rules of procedure or conduct. 2)A standard that has been adopted by one or more governmental bodies and is enforceable by law, or when it has been incorporated into a business contract.

16. NDT Standards ASTM International SAE (Society of Automotive Engineers) AISI (American Iron and Steel Institute) AWS (American Welding Society) ASME International – Boiler and Pressure Vessel Code – complete set $14,500 – Section V – Nondestructive Examination - $490 for 2010 version – Section XI – Rules for Inservice Inspection of Nuclear Power Plant Components - $680

17. American National Standards Institute (ANSI) Founded in 1918 Accredits the procedures for standards-developing organizations (SDOs) – Procedures must meet the requirements of openness, balance, consensus, and due process – Hundreds of “traditional” SDOs 20 largest produce 90% of all standards – Hundreds of “non-traditional” SDOs – Approximately 10,000 standards approved by ANSI
