Off-Road Self-Propelled Work Machines Operator enclosure environment Part 1:Terms and definitions


J3078 provides test methods and criteria for the evaluation of the operator enclosure environment in Off-Road Self-Propelled Work Machines as defined in J1116 and Agricultural Tractors as defined in ANSI/ASAE S390 and consists of the following parts: Part 1: Terms and definitions Part 2: Air filter element test method Part 3: Pressurization test method Part 4: Heating, ventilating and air conditioning (HVAC) test method and performance Part 5: Windscreen defrosting system test method Part 6: Determination of effect of solar heating J3078/1 consists of the terms and definitions which are used in the other parts of J3708.


There are currently 2 ISO documents and several J documents covering test procedures relating to operator enclosure environment. The ISO documents are basically several J documents combined into the ISO format. Technical content of all these documents was prepared by SAE SC6. This new document will contain the same technical content as the other documents but can be applied to vehicles not covered by the ISO documents. Several J documents will be replaced. Changes to the technical content of this new document will be controlled by SAE SC6. Since the format of the new document will be the same as the ISO format, it will be simpler for the SAE liaison group to present any changes to ISO.
