2、s 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 of the

3、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.

The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not en

5、sure 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 design

6、ated 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 Americ

7、an 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 and ma

8、terially 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 be revis

9、ed or withdrawn at any time. Additionally, procedures of ASABE require that action be taken periodically to reaffirm, revise, or withdraw each standard.

ISO 14269-1:1997, Tractors and self-propelled machines for agriculture and forestry Operator enclosure environment Part 1: Vocabulary. 3 Definitions For the purposes

22、 of this part of ISO 14269, the definitions given in ISO 14269-1 apply, of which the following are particularly relevant. 3.1 pressurization: Pressure differential between the static pressure inside and outside of the operator enclosure. ISO 14269-1:1997, definition 2.12 3.2 pressurization system: M

23、eans used to pressurize the operator enclosure including any components which influence the performance of the system. ISO 14269-1:1997, definition 2.13 4 Test equipment 4.1 Device to measure pressurization, with a measuring accuracy of 10% of the observed values. 4.2 Device to measure blower voltag

24、e, with a measuring accuracy of 2% of the observed values. 5 Test conditions 5.1 The pressurization system shall be completely powered by the standard equipment on the test machine with the engine operating at rated speed. The voltage at blower motor terminals shall be no more than 20% above the nom

25、inal rating of the system (for example 14,4 V for a 12 V system). 5.2 All machine accessories pertinent to the operation of the operator enclosure, enclosure components and blowers shall be standard production parts or the equivalent, adjusted within the machine manufacturers specification limits. C

26、lean air filters are recommended since the amount of dirt in the filters may affect pressurization. 5.3 An operator may be present in the operator enclosure throughout the duration of the test. 6 Test procedure 6.1 Operate the pressurization system for a minimum of 15 min prior to obtaining data. Th

27、e pressurization system shall be operated using maximum outside air, with maximum blower speed setting. No automatic pressurization controls shall be locked out. 6.2 To obtain uniform results, neither the air conditioning nor heating systems shall be in operation during the pressurization system tes

28、ts. 6.3 Record, for information purposes only, the blower voltage, ambient temperature, barometric pressure, wind velocity, and wind direction in elation to the machine centreline.
