This Standard establishes the conditions, test procedures, environment, and instrumentation for the determination and reporting of the A-weighted sound pressure level of electric battery and internal combustion engine powered, low lift, high lift, and rough terrain industrial trucks. It excludes earthmoving machinery, industrial cranes, and vehicles intended primarily for use on public roads. It provides test procedures for measuring both operator and bystander exposure to sound produced by the trucks. The test procedures set forth in this Standard provide the basis for determining the contribution powered industrial trucks make to the overall sound level of a selected work area.
