This document describes the equipment required and the procedures to be followed in measuring exhaust emissions from heavy-duty diesel engines. For clarity and continuity, this document is structured to be totally compatible with the proposed heavy-duty gaseous emission regulations (Federal Register, Vol. 44, No. 31, February 13, 1979). It should be noted that (1) this procedure does not negate or adversely affect the proposed heavy-duty regulations, but merely specifies the additional equipment and steps necessary for diesel particulate testing; and (2) this format incorporates diesel particulate testing for the 1983 and later model years. Sections in the proposed heavy-duty gaseous emission regulations which are affected by the incorporation of particulate testing are included in this recommended practice. A vertical line in the left margin indicates that a change to the proposed regulations has been made on the adjacent line of the text. The specific changes are enclosed in brackets.
