by the American Society of Mechanical Engineers (ASME), or equivalent quality standards. 1 Copies of ASME standards discussed herein may be obtained from the American Society of Mechanical Engineers, Three Park Avenue, New York, New York 10016-5990; telephone (800) 843-2763; http://catalog.asme.org/home.cfm?CATEGORY=CS&TaxonomyItemID=3021.
