Book Description
This SAE Recommended Practice establishes a uniform test procedure for determining performance levels of operator enclosure panel type air filters on off-road, self-propelled work machines used in construction, general-purpose industrial, agriculture, and forestry as defined in SAE J1116 and equipped with an operator enclosure with a powered fresh air system. The following operator enclosure air filter guideline has been established to cover dry type cab air filters used on off-road, self-propelled work machines.The objective of this procedure is to provide a uniform means for evaluating the performance characteristics of enclosure air filters on bench test equipment. The data collected by this test procedure can be used to establish standards of performance for enclosure air filters. Variations in actual field operating conditions are difficult to duplicate; however, with the procedure and equipment set forth, comparisons of air filter effectiveness can be made.In the past, there have been numerous configurations of test housings. All of these designs have had one objective, to provide uniform dust loading throughout the entire area of the filter.The performance characteristics of greatest interest are air flow restriction or pressure drop, particulate collection efficiency, and particulate capacity. These test recommendations are defined under air cleaner test code SAE J726; however, the test shroud configurations defined in SAE J726 are not applicable for operator enclosure filter comparison.

Book Description
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. 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.

Book Description
This SAE test method establishes a uniform test procedure for determining the gravimetric (mass based) efficiency and pressure drop performance levels of operator enclosure panel type filters on off-road, self-propelled work machines used in earth moving, and forestry, as defined in SAE J1116 and for agricultural equipment as defined in ANSI/ASAE S390, and equipped with an operator enclosure with a powered fresh air system. ISO/TS 11155-1 may additionally be used, which describes the use of particle sizing devices to measure the fractional (particle size) efficiency of panel type filters for automotive cabin filter applications. Automotive cabin filters are similar to filters described in this procedure, and the ISO/TS 11155-1 test method is therefore directly applicable. Minor revisions to document to correct misspelled words, obsolete test specifications, and minimal changes in procedure.

Book Description
The fourth edition of the Handbook of Human Factors and Ergonomics has been completely revised and updated. This includes all existing third edition chapters plus new chapters written to cover new areas. These include the following subjects: Managing low-back disorder risk in the workplace Online interactivity Neuroergonomics Office ergonomics Social networking HF&E in motor vehicle transportation User requirements Human factors and ergonomics in aviation Human factors in ambient intelligent environments As with the earlier editions, the main purpose of this handbook is to serve the needs of the human factors and ergonomics researchers, practitioners, and graduate students. Each chapter has a strong theory and scientific base, but is heavily focused on real world applications. As such, a significant number of case studies, examples, figures, and tables are included to aid in the understanding and application of the material covered.
