1、 ANSI/ASAE S276.8 APR2016 Slow-Moving Vehicle Identification Emblem (SMV Emblem) 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 b

2、iological 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 r

3、esource 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 engaged

4、 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 responsible

5、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 Pra

6、ctices 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, consensus,

7、 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 not n

8、ecessarily 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 CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time.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 periodic

9、ally to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

14、nuary 2005, revised September 2010; revision approved by ANSI September 2010; Corrigendum 1 issued March 2011; revised April 2016. Keywords: Emblem, Slow-moving, SMV, Speed, Vehicle 1 Introduction Implements of husbandry/agricultural equipment and other slow-moving machines, either self-propelled or

15、 towed, are often moved between operational sites that are not contiguous. Transport may involve moving on public roads (infrastructure) at ground speeds less than 40 km/h (25 mile/h). This standard provides a means of identifying such slow-moving equipment to communicate to third parties traveling

16、on such public roads as to the relative speed of such equipment to other vehicles utilizing the public roads. 2 Purpose and Scope 2.1 This Standard establishes specifications that define a unique identification emblem, the Slow-Moving Vehicle Emblem (SMV Emblem), to be used only for slow-moving mach

17、ines (vehicles), when operated or traveling on public roads. The requirements and applications of the standard are defined in the standard. The purpose is to communicate to third parties the slower speed capabilities of the slow-moving vehicle to other vehicle(s) using public roads. The primary appl

18、ication of this SMV emblem will be with implements of husbandry but may be used with other machines or vehicles that travel at speeds less than 40 km/h (25 mile/h) and in combination with a Speed Information Symbol (SIS) on vehicles which travel at speeds between 40 km/h (25 mile/h) and 65 km/h (40

19、mile/h). 2.2 This Standard establishes emblem dimensional specifications, performance requirements, related test procedures, mounting requirements and applications of the emblem. 2.3 The SMV emblem shall complement but not replace warning devices such as tail lamps, reflectors, or flashing lights. 2

20、.4 The dimensions and color patterns of the emblem have been established as a unique identification and shall not be altered to permit advertising or other markings on the face of the emblem, except as required in clause 5.2 Emblem Marking.

46、 durability. Samples installed on mounting material specified in 6.3 shall be exposed to the sun for a minimum test period of 36 months outside in south Florida, or similar natural climatic conditions, at an angle of 45 to horizontal facing upward and south, per ASTM D1014. After exterior durability

47、 test, the emblem material shall show no cracking, crazing, blistering, loss of adhesion, or dimensional change, and shall meet the requirements set forth in this Standard. 6.2.6 Color measurement. The spectrophotometric color values of the nonreflective fluorescent material shall be determined by u

Luminance shall be compared to that of a NIST (National Institute of Standards and Testing) defined perfect reflecting diffuser (PRD) for CIE (Color Institute) illuminant D65. As these nonreflective fluorescent identi

49、fication emblems can be expected to be viewed with an angular subtend of 4 at the eye, it is recommended that the CIE XYZ values be calculated using the CIE 1931 (2) standard observer and CIE illuminant D65. The CIE chromaticity coordinates, x and y, shall be calculated as given below and defined in clause 7.4 of ASTM E308. CIE Y = CIE Y CIEZYXXx+= CIEZYXYy+= For example, given CIE X = 37.87, Y = 34.05, and Z = 32.18 for 2 D65 conditions, luminance factor Y = 34.05, chromaticity values are x = 0.3638 and
