This document specifies cleanliness assessment procedures for evaluating the amount of debris present
on the clean side of the constituent parts of high pressure gasoline direct fuel injection systems. The
presence of such debris could lead to a reduction in the system’s operational performance.
While other International Standards (e.g. ISO 16232 series) relate to the cleanliness of different types of
components used in road vehicle fluid circuits, this document focuses on the special procedures applied
for the components of gasoline direct fuel injection systems.
