9VAC5-91-790. ASM start-up standards

ASM Exhaust Emission Standards The following standards shall apply upon implementation of the emissions inspection program. The exhaust emissions standards for the following model years are cross-referenced by using the number in the column in Table 14.1 to locate the column that lists the appropriate standards in the look up tables in 9VAC5-91-810 . Each column reference below corresponds to two columns, one for the ASM 5015 and one for the ASM 2525, in 9VAC5-91-810 . The test standards are then listed in the appropriate column according to the Equivalent Test Weight. TABLE 14.1 TABLE 14.1 Light Duty Vehicles. Light Duty Vehicles.
