ISO 8178-2:2021

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).
