11、ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, go
12、vernmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IE
13、C Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the memb
14、er bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10263-3 was prepared by Technical Committee ISO/TC 127, Earth-moving ma

18、e maximum pressurization inside an operator enclosure of an earth-moving machine when equipped with a pressurization system. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For und
19、ated references, the latest edition of the referenced document (including any amendments) applies. ISO 10263-1, Earth-moving machinery Operator enclosure environment Part 1: Terms and definitions 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 10263-
20、1 and the following apply. 3.1 pressurization pressure differential between the static pressure inside and outside of the operator enclosure 3.2 pressurization system means used to pressurize the operator enclosure, including any components which influence the performance of the system 4 Test equipm
21、ent 4.1 Device to measure pressure with a measuring accuracy of 5 % of the observed values. 4.2 Voltmeter or other voltage measuring device to measure blower voltage, with a measuring accuracy of 2 %. 4.3 Thermometers or other temperature measuring devices, with a measuring accuracy of 0,5 C. 4.4 De
22、vice to measure barometric pressure, with a measuring accuracy of 2 % of the observed values. 4.5 Anemometer to measure wind speed, with a measuring accuracy within 0,5 m/s. BS ISO 10263-3:2009ISO 10263-3:2009(E) 2 ISO 2009 All rights reserved5 Test conditions 5.1 The pressurization system shall be
23、completely powered by the standard equipment on the test machine with the engine operating at rated speed when the engine or other components influence the environment within the operator enclosure. The voltage at blower motor terminals shall be no more than 15 % above the nominal rating of the syst
24、em (for example 13,8 V for a 12 V system). 5.2 All machine accessories pertinent to the operation of the enclosure, enclosure components and blowers shall be standard production parts or the equivalent, adjusted within the machine manufacturers specification limits. Clean air filters are recommended
25、 since the amount of particulate matter in the filters may affect the pressurization. 5.3 It is recommended that the test be conducted in a controlled inside environment to minimize the influence of wind speed on the vehicle pressurization. 5.4 If the vehicle must be tested in an outside environment
26、, the vehicle must be oriented such that the normal operating direction of the vehicle is facing into the wind, and the wind direction is not more than 30 off the vehicle centreline. Test data must not be recorded when the wind speed is greater than 5 m/s. 5.5 An operator may be present in the enclo
27、sure throughout the duration of the test. 5.6 Maximum wind speed passing the machine: 5 m/s. 6 Test procedure 6.1 Operate the pressurization system for a minimum of 15 min prior to obtaining data. The pressurization system shall be operated using maximum outside air, with maximum blower speed settin
28、g. No automatic pressurization controls shall be locked out. 6.2 To obtain uniform results, neither the air conditioning nor heating systems shall be transferring heat during the pressurization system tests. 6.3 Record, for information purposes only, the blower voltage, ambient dry bulb temperature,
29、 barometric pressure, wind speed, and wind direction in relation to the machine centreline. 6.4 Record enclosure pressure in pascals (Pa). 6.5 The pressure measuring device shall be positioned to avoid velocity head by keeping its reference and measuring points away from air streams. 7 Test report T
30、he obtained enclosure pressure (Pa) shall be included in the test report. An example of a suitable test report form is given in Annex A.
