GSO ISO 8178-3:2013 Scope
This part of IS0 8178 specifies two methods for the
measurement of exhaust gas smoke characteristics
of reciprocating internal combustion (RIG) engines
operating under steady-state conditions. One method
evaluates smoke opacity by measurement of the
obscuration of a light beam; the other evaluates the
soot content by measurement of the blackening of a
filter. Where necessary, individual requirements may
be specified for particular engine applications.
This part of IS0 8178 does not deal with measurement
under transient conditions; if smokemeters are
used under transient conditions, the results from different
types of instrument cannot be compared unless
the sampling conditions are identical and the
instrument characteristics are compatible.
This part of IS0 8178 is applicable to RIC engines for
land, rail-traction and marine use, including engines
used to propel agricultural tractors and road vehicles.
It may be applied to engines used to propel roadconstruction
and earth-moving machines, industrial
trucks, and for other applications where no suitable
International Standards for exhaust gas smoke
measurement of these engines exist.
