How to be Compliant with ISO or VDA 19 in Automotive Components Manufacturing

Why does the product need perform technical cleanliness testing?

1. Tighter tolerances make products more sensitive to contaminants and residues. 

2. Cleanliness is related to product lifespan.

3. Large contaminant particles (killer particles) can cause equipment failure, malfunction, or loss of control. 

4. Exhaust gas recirculation components require extremely smooth (scratch-free) surface finishes.

5. Noise control components require extremely smooth (scratch-free) surface finishes. 

6. Recycling laws require lead-free products (extremely stringent residue requirements).

How to do technical cleanliness inspection process?
