LEGEND
ESC - Emission Standard Category
GVWR - Manufacture's Gross Vehicle Weight Rating LVW - Loaded Vehicle Weight
PC - Passenger Car
LDT1 - Light-Duty Truck up through 3750 LVW and GVWR no greater than 6000 lbs. LDT2 - Light-Duty Truck greater than 3750 LVW and GVWR no greater than 6000 lbs. MDV - Medium-Duty Vehicle, GVWR from 6001 to 8500 lbs.
HC - Hydrocarbon, ppm CO - Carbon Monoxide, % NO - Nitric Oxide, ppm
PASS/FAIL EMISSION STANDARDS = A+B / VTW
PASS/FAIL STANDARDS - Emission standards used to determine if a vehicle passes the emission inspection. A vehicle passes if the emission levels are equal to or less than the standards for HC, CO and NO for ASM 5015 and ASM 2525.
GROSS POLLUTER STANDARDS - Emission standards used to designate a vehicle as a gross polluter. A vehicle is designated as a gross polluter if the emission levels at the time of the initial inspection, before repairs are greater than the gross polluter standards for HC, CO or NO for ASM 5015 or ASM 2525.
NOTE: If test data on emission pass/fail rates or gross polluter identification rates indicate adjustments are required, the emission standards may be increased or decreased by the bureau by 30% or by the following tolerances, or standards may be set for any specific vehicle and engine configuration which the bureau determines has excessive errors of commission of omission, whichever is necessary to comply with Section 44001.5 of the Health and Safety Code.
