Heavy duty engines. Measurement of gaseous emissions from raw exhaust gas and of particulate emissions using partial flow dilution systems under transient test conditions1 Scope This International Standard specifies methods for the measurement and evaluation of gaseous and particulate exhaust emissions from heavy duty engines under transient conditions on a test bed. The procedures it defines can be applied to any transient test cycle that does not require extreme system response times; it can therefore be used as an option to the regulated measurement equipment of certification test cycles usually CVS type systems
