N2 - Recently, the clean air support system (CAPSS) pronounced that construction machinery is the second-largest source of pollutants in Non-road mobile machinery (NRMM) after ship. Three types of vehicles, forklifts, excavators, and loaders, account for 80 % of pollutants emitted by all construction machinery. In addition, domestic construction emission regulation has been reinforced by adopting the EU Stage V regulations. Therefore, it is necessary to analyze the domestic and overseas construction machinery regulations and perform emission test under real operation condition. In this study, three construction machineries (1 unit each of forklift, excavator, and loader) were selected as test vehicles. The emissions were measured using a portable emissions measurement system (PEMS) installed on the test vehicles. The real operation test was conducted in accordance with EU Stage V ISM policy emission measurement procedure. The real operation test cycles were developed for each vehicle type to meet the minimum test duration requirement. Additionally, the test data were evaluated to distinguish valid working events and analyze emission characteristics using the moving average window (MAW) analysis method.
