1、 ASABE/ISO 23205:2014 FEB2016 Agricultural tractors Instructional seat 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, and biological
2、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 water resource ma
3、nagement, 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 engaged in indust
4、ry 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 responsible for protec
5、ting 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 Practices and
6、 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, consensus, and other
7、 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 not necessarily
8、 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 CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time.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 periodically to re
9、affirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

14、SO 23205:2014, Agricultural tractors Instructional seat, is an adoption without modifications of the identically titled ISO standard ISO 23205:2014, Agricultural tractors Instructional seat. 0.2 ASABE/ISO 23205:2014 specifies the minimum design and performance requirements for an instructional seat
15、and restraint designed for limited use by a trainer or trainee or service person inside an enclosed cab of an agricultural tractor. The instructional seat is neither intended for, nor is it designed for use by, children. 0.3 Four normative references are listed in ISO 23205:2014. These references ha
16、ve been reviewed and accepted as part of the adoption of ASABE/ISO 23205:2014. 0.4 This standard has been approved as an American National standard by ANSI (American National Standards Institute).

The instructional se
25、at shall be placed such that the trainer, trainee or service person seated in it has a minimal potential impact on operation and visibility, in keeping with intended use, and consistent with machine function and other design considerations. 4.4 The instructional seat may or may not be padded or cush
26、ioned. Its backrest shall also have minimum dimensions according to Figure 1. A non-glazed component at the rear or side of the enclosed cab, or a cab wall, may be used as the backrest, provided the dimensional requirements are met. The backrest may or may not be padded or cushioned. 4.5 At least on
