1、 ANSI/ASAE S584.3 JAN2013 Agricultural Equipment: Speed Identification Symbol (SIS) American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering applicable to agricultural, food, an
2、d biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead equipment, structures, soil and wate
3、r resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only. Their use by anyone enga
4、ged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordinances, laws and regulations. Prospective users are responsib
5、le for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the revision approval date. Newly developed Standards, Engineering
6、Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the requirements for due process, consens
7、us, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but no
8、t necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require that action be taken perio
9、dically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

11、ary 2005; approved by ANSI January 2005; revised August 2006; revision approved by ANSI August 2006; revised December 2011; revision approved by ANSI December 2011; revised January 2013; revision approved by ANSI February 2013. Keywords: SIS, SMV, Speed, Symbols Introduction Implements of husbandry/
12、agricultural equipment operations include the transport of commodities and equipment from the field sites to farmsteads, storage facilities and gathering points for movement by mass transit systems. Equipment often moves between farmsteads and field sites that are not contiguous. Transport may invol
13、ve moving on public roads (infrastructure) that permits faster ground speeds than that which is used in the fields or within the design considerations of the equipment. Design approaches have been identified to permit selected equipment to move at faster ground speeds in transport configurations. Th
14、is standard provides a means of identifying equipment that has been specifically designed for ground speeds greater than 40 km/h (25 mile/h) but under 65 km/h (40 mile/h), when operating or traveling on public roads. The means of identification is a Speed Identification Symbol (SIS). 1 Scope 1.1 The
15、 scope of this standard is primarily directed to identifying agricultural equipment (implements of husbandry) that have been designed in their original equipment configuration for specified ground speeds greater than 40 km/h (25 mile/h) but under 65 km/h (40 mile/h). 1.2 The standard applies to self
16、 propelled, semi-integral and towed equipment moving on public roads. 1.3 The Speed Identification Symbol (SIS) identifies the maximum equipment ground speed based on the ground speed design capability of the specified piece of equipment. 1.4 The SIS will be used in conjunction with the Slow-Moving
17、Vehicle Emblem (SMV Emblem), ASAE S276. 1.5 The SIS will convey the above information to other operators on public roads approaching from behind the equipment, or for notifying authorities of the equipments specified ground speed capabilities. 1.6 Mounting of the SIS on the front of towed equipment
18、will serve to alert operators of the towing vehicle of the maximum specified ground speed capabilities at which the equipment combination may be operated. 2 Normative References The following referenced documents are indispensable for the application of this document.
