ISO or VDA 19 Components Cleanliness

In the early 1960s, the American Automotive Engineers established terminology for cleanliness. Today, cleanliness continues to expand to almost all industrial fields. For the automotive industry, as components become more complex and functional requirements increase, technical cleanliness standards will become an indispensable step in optimizing the automotive manufacturing process. As many vehicle components require extremely high reliability and lifespan, ensuring the cleanliness of components directly impacts product quality.

Cleanliness issues generally relate to particulate contaminants. Component residue and lethal particles are responsible for over 80% of early mechanical system failures and warranty claims. Cleanliness inspection aims to precisely evaluate contamination levels, thereby providing effective feedback for the manufacturing process to eliminate safety risks associated with part failure.

Gravimetric Analysis: Weighing the extracted particles to assess contamination.

Particle Sizing: Evaluating particle length and width (identifying worst-case lethal particles).

Elemental Analysis (LIBS/SEM): Determining the chemical composition of particles to trace the contaminant source.
