Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means m

The standard is a revision of American National Standard for Snow throwers - Safety specifications, ANSI/OPEI B71.3 -1995. The present revision was prepared by the B71.3 Comm
19、ittee on Snow Throwers as part of OPEIs continuing work on standards. The principal purpose of this revision was to update the scope, to include commercial turf machine attachments, address hand-in-chute accidents, and eliminate some tests that are not relevant. Consensus for this standard was achie
20、ved by use of the Canvass Procedures. Suggestions for improvement of this standard will be welcome. They should be sent to the Outdoor Power Equipment Institute, Inc., 341 South Patrick Street, Alexandria, VA 22314. The following organizations and individuals, recognized as having an interest in the
21、 standardization of safety requirements for snow throwers, were contacted prior to the approval of this revision of the standard. Inclusion in this list does not necessarily im- ply that the organization concurred with the submittal of the proposed standard to ANSI. American Consulting and Testing,
