Common standards for cleanliness testing of auto parts

Cleanliness standards such as VDA19.1 and ISO16232 are the most widely used cleanliness standards in the automotive industry.

VDA19.1 is the cleanliness standard launched by the German Automobile Industry Federation, which elaborates the cleaning method and particle size analysis method of auto parts in detail, and points out the direction for the cleanliness detection of the automobile manufacturing industry.

ISO16232 international cleanliness standard, divided into 10 parts.

Part 1: Vocabulary

Part 2: Methods for extracting contaminants with mechanical stirring

Part 3: Methods of high-pressure water extraction of contaminants

Part 4: Methods for the extraction of contaminants by ultrasonic technology

Part 5 Methods for Extraction of Contaminants by Multifunctional Test Bench

Part 6: Gravimetric determination of particle mass

Part 7: Determination of particle size and count by microscopic analysis

Part 8: Determination of particle nature by microscopic analysis

Part 9: Determination of particle size and counts with automated extinction particle counters

Part 10: Presentation of results

Some car companies also have their own industry standards:
