Technical cleanliness inspection to VDA 19.1 and ISO 16232
VDA 19.1 and ISO 16232 describe how to inspect the technical cleanliness of parts, that is, how much particulate contamination remains on their surfaces and inside them after production. Our accredited testing laboratory (accreditation number AB 1836) carries out these inspections for the automotive industry, aviation, mechanical engineering and precision electronics.
What do VDA 19.1 and ISO 16232 cover?
ISO 16232 is an international standard that describes methods for inspecting the technical cleanliness of parts and components, above all in the automotive industry. VDA 19.1 is a guideline of the German Association of the Automotive Industry (VDA) that supplements ISO 16232 with detailed procedures for extraction, filtration, particle analysis and reporting of results. The result shows whether the part meets the customer’s cleanliness specification.
How does an inspection in our laboratory work?
- Extraction – we remove contaminants from the surfaces and the inside of the part by pressure rinsing, internal rinsing or ultrasonic extraction, chosen to suit the shape of the part,
- Filtration – the test liquid with the contaminants passes through an analysis filter, which retains the particles,
- Light-optical analysis – we measure the size, number and shape of the particles on the filter,
- Gravimetric analysis – we weigh the mass of the contaminants,
- Test report – the results described as required by the standard.
Why an accredited laboratory?
Our laboratory has been accredited by the Polish Centre for Accreditation (PCA) since 9 May 2022, accreditation number AB 1836, in line with PN-EN ISO/IEC 17025. Inspections to ISO 16232, VDA 19.1 and VDA 19.2 are reliable and repeatable, and the result can serve as official proof of quality for automotive customers.
Frequently asked questions
What is the difference between VDA 19.1 and ISO 16232?
ISO 16232 is an international standard, while VDA 19.1 is a guideline of the German automotive industry that supplements it with detailed procedures. We inspect to both.
What does the inspection result include?
A test report: the number and size of particles from the light-optical analysis and the mass of contaminants from the gravimetric analysis.
