VDA Band 19.1

Technical cleanliness and particle contamination analysis

VDA Band 19.1 is a German automotive industry standard that defines cleanliness requirements and testing procedures for functionally relevant components in fluid circuits. It specifies sampling methods, particle extraction techniques, and contamination classification compatible with ISO 4406 codes. This standard is widely used by Tier 1 suppliers and OEMs in Germany and central Europe to verify component integrity before assembly. Accreditation to this standard demonstrates laboratory competence in precise particle quantification and adherence to stringent German automotive quality expectations.

What it measures

  • Particle count and size classification (ISO 4406 compatible)
  • Cleanliness class of functional components
  • Surface contamination of injectors, valves, and pumps
  • Acceptable contamination thresholds per application
  • Particle morphology and composition
