5、esultsof the test will be equivalent. The differences in the documents are as follows:The scope of J1012 (Section 1) encompasses all off-road self-propelled equipment - ISO 3737 (Section 1)is limited to agricultural tractors and self-propelled machines.Section 5.3 of J1012 allows one occupant to be
6、in the cab during the test - Section 4.3 of ISO 3737specifies the enclosure to be unoccupied.1. ScopeThis SAE Recommended Practice establishes a uniform test procedure for evaluating performance ofoperator enclosure pressurization systems for construction, general-purpose industrial, agricultural, f
7、orestry,and specialized mining machinery as categorized in SAE J1116 for off-road, self-propelled work machines.1.1 PurposeThe purpose of this document is to outline a procedure which will provide a uniform measurementof operator enclosure pressurization.2.

13、 Its maximum error shall not exceed 10%.4.2 A voltmeter to monitor voltage in the pressurizer electrical system during the test. Its maximum error shall notexceed 2%.5. Test Conditions5.1 The pressurizer system shall be completely powered by the standard equipment on the test machine, with theengine
14、 operating at rated speed. The voltage at the blower terminals shall be no more than 20% above thenominal rating of the system. (Example: 14.4 V for a 12 V system.)5.2 All machine accessories pertinent to operation of the enclosure, enclosure components, air filters, and blowersshall be standard pro
15、duction parts or equivalent, adjusted within the manufacturers specification limits. Cleanair filters are recommended since the amount of dirt in the filter may affect pressurization.5.3 No more than one occupant may be inside of the operator enclosure during the test.6. Test Procedure6.1 The operat
16、or enclosure shall be equipped with all applicable equipment (see 3.2). The pressurizer systemshall be operated using maximum outside air, with the maximum blower speed setting. Any automaticpressurization controls shall not be locked out. The pressurization system shall be in operation for a minimu
17、mof 15 min prior to obtaining data.6.2 To obtain uniform results, neither the cooling nor heating system shall be in operation during the pressurizationsystem tests.6.3 The blower voltage, ambient temperature, barometric pressure, wind velocity, and wind direction in relation tothe machine centerlin

It also expands the scope to include other off-road self-propelled work machines, since i
22、t currently applies only to agricultural tractors.Relationship of SAE Standard to ISO StandardTechnically equivalent to ISO 3737 with the followingexceptions:J1012 covers all off-road self-propelled machines while ISO 3737 covers only agricultural tractors andself-propelled machines.J1012 allows one
23、 occupant to be in the cab during the test while ISO 3737 specifies that enclosure shallbe unoccupied.ISO/DIS 10263 is a document which encompasses several SAE standards relating to the OperatorEnclosure including the elements of J1012.
