1、 ASABE/ISO 14269-3:1997 (SEP2006) (R2017) Tractors and self-propelled machines for agriculture and forestry Operator enclosure environment Part 3: Determination of effect of solar heating American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of

2、 members worldwide, who are dedicated to advancement of engineering applicable to agricultural, food, and 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

3、of the Society; principally agricultural field equipment, farmstead equipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management.

4、Standards, Engineering Practices, and Data are informational and advisory only. Their use by anyone engaged 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

5、 not ensure compliance with applicable ordinances, laws and regulations. Prospective users are responsible 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

6、 designated as “ASAE“, regardless of the revision approval date. Newly developed Standards, Engineering 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

7、 American National Standard requires verification by ANSI that the requirements for due process, consensus, 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

8、 and materially affected interests. Substantial agreement means much more than a simple majority, but not 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 b

26、s, in the same general area as the operator enclosure under test. Measure the radiance at 10 min intervals during the test period. These readings shall be averaged and recorded as part of the reported results. 5.2 A measured average solar radiant energy of 950 W/m2 95 W/m2is considered normal test c

28、nder test when measured in all four directions. 6.3 In order to simulate the effects of solar heating, the light source shall have 45% or more of its radiated energy above 700 nm. It is recommended that the method of controlling the intensity not change the spectral distribution of the lamps. ASABE/

31、level shall be adjusted to an average of 950 W/m2 95 W/m2. No individual reading shall vary by more than 10% from the average. 7.5 The intensity level shall be recalibrated every six months or every time the elevation of the roof line of the operator enclosure being tested is changed.
