We found this article regarding cleaning standards and best practices as advocated by our friends in Europe interesting.
The German Association of the Automotive Industry’s VDA Volume 19 is the first comprehensive standardization document for characterizing the cleanliness of products within the automotive industry’s quality chain.
Defined standards for residual particulate contamination of functionally relevant components in the automotive industry are self-evident today. This is especially true in Europe, where the German Association of the Automotive Industry’s VDA Volume 19 is the first comprehensive standardization document to deal with the approaches and procedures for characterizing the cleanliness of products within the automotive industry’s quality chain.
As more manufacturers and finishers in the U.S. look to see if VDA 19 standards may come to the North American supply chain, attention should be paid not only to the cleaning process, but to the entire process chain. Even the tiniest particles left behind in the wrong place can cause damage and system failures. “Technical cleanliness” is therefore a quality criterion, particularly when it comes to parts for the automotive industry, precision engineering and hydraulics.
