Off-Road Self-Propelled Work Machines Operator Enclosure Environment - Part 2: Air Filter Element Test Method
J3078/2_202301
SAE J3078/2 provides a test method to determine filter performance for fresh and recirculation air filters used in operator enclosures with an air ventilation system. SAE J3078/2 is not applicable for testing vapor and gas filters. The category of machines covered includes off-road self-propelled work machines as defined in SAE J1116 and tractors and machinery for agriculture and forestry as defined in ASABE standard ANSI/ASAE S390.
Rationale:
SAE J3078/2 is being revised because of the changes made to SAE J3078-4, which overlap with SAE J3078/2. Additional changes were also necessary to harmonize SAE J3078/2 with ISO 23875:2021 Amd 1.
This SAE filter test standard provides a standard test method, for general use filters.
Fractional efficiency testing determines the efficiency of the filter at specific particle sizes. This test method is used when quantifying particulate efficiency for filtration used in human respiratory environments; i.e., operator enclosures.
ISO 11155-1 is a fractional efficiency test method that addresses a wide variety of filter media types, filter shapes, efficiency requirements, and airflow ranges that are utilized in modern operator enclosures.
