2、f an American National Standard requires verification by ANSI that the requirements for due process, consensus and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has bee
3、n reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American Natio

Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for

This standard was developed after intensive study of existing practices, standards and literature. The intent of this document is to offer to rotating equipment
22、designers and users a standard for design practice and dimensions regarding keyless fits for flexible couplings. In general, the information in this standard is a consolidation of the most common practices and standards currently in existence. This AGMA standard and related publications are based on
23、 typical or average data, conditions, or applications. Work was begun on ANSI/AGMA 9003-A91 in 1985 and was approved by the AGMA membership in February 1991. It was approved as an American National Standard on May 20, 1991. ANSI/AGMA 9003-B08 split the original standard into inch and metric versions
24、 (ANSI/AGMA 9103-B08), updated Annex B and added an example calculation as Annex D. The first draft of ANSI/AGMA 9003-B08 was made in October 2004. It was approved by the AGMA membership in October 2007. It was approved as an American National Standard on May 20, 2008. ANSI/AGMA 9003-C17 provides a
