ANSI/AGMA 6025-D98 (R2016)
Sound for Enclosed Helical, Herringbone, and Spiral Bevel Gear Drives
Concern with industrial noise created a need for acoustical standards covering all types of gear products. Noise measurement and control is dependent upon the individual characteristics of the prime mover, gear unit and driven machine as well as their combined effects as a system in addition to the effects of the acoustic environment. The complexity makes most sound standards difficult to apply or interpret properly. The AGMA Acoustical Technology Committee developed this standard for the purpose of providing improved communication between purchaser, gear manufacturer and user in the areas of sound instrumentation, sound measurements and test procedures. Because of the many variations of system response in different acoustic environments, this standard identifies certain areas where special test conditions might be necessary and should be part of the contractual agreement between purchaser and gear manufacturer. The first draft of ANSI/AGMA 6025-C90 was prepared in January 1989 as a revision of AGMA 297.02. AGMA 297.01 was first approved by the AGMA membership in July of 1973. The standard presented the A-weighted sound pressure level measurement procedures for enclosed helical, herringbone and spiral bevel gear drives. Work began on a revision of AGMA 297.01 in 1979 to update the terminology and to add an appendix, a procedure for sound power measurements. AGMA 297.02 was approved for printing and distribution in 1983. This revision of AGMA 297.02 also incorporates AGMA 295.04 and AGMA 298.01, which were similar in content. ANSI/AGMA 6025-C90 was approved by the AGMA membership and the American National Standards Institute in 1990. This revision of the 1990 standard is a modification incorporating the procedures from ISO 8579-1:1993 as a normative annex, updating of references and including additional information. There are four annexes in this standard. Annex A is normative and is considered part of this standard when specified; Annexes B, C and D are informative and are not considered part of this standard. ANSI/AGMA 6025-D98 was approved by the AGMA membership in March 1998. It was approved as an American National Standard on June 19, 1998.
