ISO 23875 Validation Study Using
ISEEE In-field Testing Method
On August 14, 15, and 16th, testing was done to determine the air quality within three Large Haul Trucks (LHTs) which travel over gravel roads carrying heavy loads.
The test evaluated the dust concentration levels, CO2 concentrations, and cab pressurization while in real-time, real-world operations.
The tests were performed using the International Society of Environmental Enclosure Engineers (ISEEE) test belt and in-field test method. The results of the test are evaluated as a part of this study.
Recommendations given are based upon the best practice approach to operator enclosure engineering requirements as described in the ISEEE Advanced Cab Theory Workbook.
