Typical duration for these emissions tests isfrom 20 minutes to 1 hour.Test results vary according to procedure/objective.Usually, regulated emissions, particulate matter, and fuelconsumption are reported. Sometimes smoke orunregulated emissions may be reported. Numerousoptions are available depending on specific client needs.Note:3SOUTHWEST RESEARCH INSTITUTESan Antonio, TexasJuly 2010
