This document specifies cleanliness assessment procedures for evaluating the amount of debris found within the clean side of diesel fuel injection assemblies, which could lead to a reduction in the system’s operational effectiveness.

ISO4406:2017 is the internationally recognised cleanliness code for measuring the solid particulate content of fuel samples and hydraulic fluid. It is also referred to as the ISO cleanliness code. For engines designed to achieve Euro 2, 3, 4 and 5 …

While other International Standards, e.g. ISO 16232, relate to cleanliness of components used in road vehicle fluid circuits, this document is focused on diesel fuel injection assemblies as supplied to diesel engine manufacturers or the service market.

Mar 23, 2020 · ISO 4406 measures the number of particles larger than 4µm, 6µm, and 14µm within the 100ml fluid sample. Using the table below, the ISO code number to the left is used to represent the number of particles per ml.

The International Organization for Standardization (ISO) created the cleanliness code ISO4406:1999 to quantify particulate contamination levels per milliliter of fluid at three sizes: 4μ, 6μ, 14μ.
