4、 of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reac
5、hed by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standa

The firstedition of thi
45、s standard was approved and published by the American National Stan-dards Institute in 1980. It has been revised five times since initial publication, includ-ing this revision.The present revision was prepared by the Outdoor Power Equipment Institute (OPEI)Subcommittee on Commercial Turf Care Equipm
46、ent as part of OPEIs continuingwork on standards.The effective implementation date of this standard shall be two (2) years after the ap-proval date and shall apply to all products built after that date. Manufacturers mayalso certify to this standard anytime after the approval date.A summary of the p
47、rincipal changes included in this revision is as follows:- Changed format of standard to harmonize with ANSI B71.1- Broadened scope of ROPS requirements for ride-on machines- Removed lateral upset test - Added specific force for guards used as steps- Changed stability test to last tire off for lift-
48、off- Hot surface requirements revised to use ISO cones- Revised guarding requirements for operator location and rotating enginescreensConsensus for this standard was achieved by the use of the Canvass Method. Thereare three annexes in this standard. Annexes A, B, and C are informative and are notcon
49、sidered part of this standard.Suggestions for improvement of the standard will be welcome. They should be sentto the Outdoor Power Equipment Institute, 341 South Patrick Street, Alexandria, VA22314 or www.opei.org.The following organizations recognized as having an interest in the standardization ofs
