Every method has its advantages and disadvantages, however different methods can lead to different results for the same pollutant being measured. On the following pages, the stack testing process is analysed in regards to the proce- dures required and the factors to be considered from the engine side. In addition, a guideline is provided to help ensure that the results of a stack test are valid and not impacted by either engine malfunctions or errors in the testing process.
