24、ot part of American National Standard ANSI/OPEI B175.1-2012.)This standard sets forth the minimum safety requirements for internal combustion en-gine-powered hand-held chain saws. These requirements have resulted from yearsof standards development efforts by the OPEI B175 Standards Committee. The or
25、ig-inal standard was approved in 1979 and revised in 1983, 1985, 1991, and 2000. This standard contains 17 annexes, 12 of which are informative. Annexes B.2, C, D,M, and N.1 are normative and are considered part of this standard.Suggestions for improvements of this standard are welcome. They should
26、be sent tothe B175.1 Standards Committee, c/o OPEI, 341 South Patrick Street Alexandria, VA22314. The following organizations recognized as having an interest in the standardization ofsafety requirements for internal combustion engine-powered hand-held chain sawswere contacted prior to the approval
27、of this revised standard. Inclusion in the list doesnot necessarily imply that the organization concurred with the submittal of the pro-posed standard to ANSI.Dr. Holger Lochmann, ChairmanGeneral Interest:Tree Care Industry Association (Peter Gerstenberger)Underwriters Laboratories (Nicolette Allen)
