ISO 8178-2:2008, together with ISO 8178-1 and ISO 8178-11, specifies the measurement and evaluation methods for gaseous and particulate exhaust emission from reciprocating internal combustion engines (RIC engines) under steady-state and transient conditions for field testing. ISO 8178-2:2008 is applied when RIC engines used in off-road vehicles, marine installations, generating sets, diesel rail traction or similar applications must be measured under field conditions or at site in order to determine the in-use compliance or when it is not possible to take the measurements under test-bed conditions or to use the test-bed measurement results.

<p>This document specifies the measurement and evaluation methods for gaseous and particulate exhaust emissions from reciprocating internal combustion engines (RIC engines) in the field.</p> <p>This document is applicable when the emissions from RIC engines used in non-road machinery, industrial equipment, marine installations, generating sets, diesel rail traction or similar machinery applications need to be measured in the field. Clause 4 applies for the conduct of discrete-mode steady-state gaseous or particulate emission measurements at a single operating point or conduct a weighted cycle-based test in the field. Clause 5 applies where it is necessary to assess gaseous emissions performance of engines during typical in-service operation under field conditions using portable emission measurement systems (PEMS).</p>
