ISO 16232:2018 defines the methods for the extraction and quantification of contamination on components through analysis of solid contaminants. It also introduces a unique and internationally recognised system for coding the level of contamination: the CCC (Contamination Classification Code).

The CCC code is a key element of the standard, used to classify the quantity and size of the detected contaminant particles. This system allows a quantitative assessment of contamination by subdividing the particles into different size classes. Thanks to this classification, the level of cleanliness of mechanical components can be effectively monitored and compared, ensuring compliance with established acceptance limits.

However, despite the existence of a standardised method for coding the level of contamination, many car manufacturers globally adopt alternative methodologies and syntax, adding specific requirements with their own terminology. These additional details require careful interpretation of the customer’s specifications to be correctly understood and applied.
