With “VDA19.2 – Technical cleanliness in assembly”, the German Association of the Automotive Industry published a guideline in 2010 that classifies different levels of cleanliness. The aim of this guideline is to help users to avoid critical particle contamination at sensitive points.
Clean rooms and cleanrooms differ primarily in the definition of the permitted particle sizes. The construction costs of a cleanroom are significantly lower than those of a cleanroom due to the less complex filter and ventilation technology and the operation is cheaper.
