Off-Road Self-Propelled Work Machines Operator enclosure environment Part 2:Air filter element test method
J3078/2 specifies a uniform test method to determine performance levels of operator enclosure panel-type air filters used to filter the air entering an earth-moving machine operator enclosure with a powered fresh air system.
Rationale: 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.
