Sec.  36.43  Determination of exhaust-gas composition.



    (a) Samples shall be taken to determine the composition of the 

exhaust gas while the engine is operated at loads and speeds prescribed 

by MSHA to determine the volume of air (ventilation) required to dilute 

the exhaust gas (see Sec.  36.45). The engine shall be at temperature 

equilibrium before exhaust-gas samples are collected or other test data 

are observed. At all test conditions the intake mixture shall contain
