12、ned to ASME N509 for nuclear power plants andother nuclear applications.This Standard provides a basis for the development of test programs and detailed acceptanceand surveillance test procedures and specifies minimum requirements for the reporting of testresults.This Standard was originally develop
13、ed by the American National Standards Committee N45on Reactor Plants. Following approval by the N45 Standards Committee, the first edition of theStandard was approved on June 19, 1975 by the American National Standards Institute, anddesignated ANSI N510-1975.In 1975, the N45.8 Subcommittee was reorg
14、anized into the ASME Committee on Nuclear Airand Gas Treatment (CONAGT) and began operating under the ASME Procedures for NuclearProjects, which received accreditation January 15, 1976. CONAGT was chartered to develop,review, maintain, and coordinate codes and standards for design, fabrication, inst
15、allation, testing,and inspection of equipment for gas treatment for nuclear power plants.Suggestions for improvement gained in the use of this Standard will be welcomed.
