ISO 12345:2002
Diesel engines — Cleanliness assessment of fuel injection equipment
ISO 12345 specifies cleanliness assessment procedures for evaluating the amount of debris found within the constituent parts of a diesel fuel injection system that could lead to a reduction in the system's operational effectiveness. It is mainly concerned with new equipment not yet fitted to an engine, and is therefore aimed primarily at engine and fuel injection equipment manufacturers.
