STDLDV represents the light-duty vehicle particulate standard. PRODLDT represents the manufacturer’s total diesel light-duty truck production for those engine families being included in the average for a given model year. STDLDT represents the light-duty truck particulate standard. Family particulate emission limit means the diesel particulate emission level to which an engine family is certified in the particulate averaging program, expressed to an accuracy of one hundredth gram-per-mile.",
