Product Code:SAE J1936
Title:Chemical Methods for the Measurement of Nonregulated Diesel Emissions
Issuing Committee:Emissions Systems Forum Committee
Scope:This SAE Recommended Practice encompasses analytical procedures for measuring nonregulated diesel exhaust emissions. Methods are recommended for the measurement of aldehydes and carbonyl compounds, sulfates and the characterization of diesel exhaust particulates. Informational methods are presented for the measurement of polycyclic aromatic hydrocarbons (PAH) in diesel exhaust particulate samples. The procedures are based on current proven chemical and engineering practices. However, it should be noted that the procedures are subject to change to keep pace with established experience and technology.
