VDA 19.1:2015 – ISO 16232:2018
A standard residual particle contamination analysis must be carried out in accordance with the test methods described in the VDA 19.1 and ISO 16232:2018 standards, using extraction, filtration, optical microscopy, and evaluation of results. In addition to the requirements specified in the standards, the laboratory must take into account customer‑specific specifications and standards, which may modify or complement the test procedures or standards VDA 19.1 / ISO 16232. Once the test has been completed, the laboratory will verify whether the sample meets or does not meet the acceptance limits provided by the requesting customer.

An extended residual particle contamination analysis is carried out following the same procedures as a standard analysis, as specified in the VDA 19.1 and ISO 16232:2018 standards. However, in this case, the analytical technique goes beyond the metallic/non‑metallic shine‑based classification.
In extended tests, additional analytical techniques such as SEM‑EDX (inorganic particles) and FT‑IR (organic particles) are incorporated to determine the true and unequivocal nature of the particle material, avoiding potential false positives and false negatives derived from metallic/non‑metallic classification.
Customer‑specific standards and specifications are of vital importance.

Sometimes the components to be inspected are very large. They cannot be moved or properly clamped, and the extraction phase of the test becomes a highly complex process. This is the case for battery housings, large pipes, crankcases, or crankshafts, where each area must also be tested in a specific manner.
At BIDEA LAB, we have dedicated extraction systems designed for this type of product. Our team of analysts travels to the customer’s facilities to carry out the extraction phase of the test on‑site, ensuring the equipment’s blank value.
Once the on‑site extraction has been completed, the test continues in the laboratory’s clean room, following from that point onward the standard phases of a complete clean room test.

Has your customer provided you with a specification that refines or complements the test standard? We work with numerous customer‑specific standards—see a sample below. Can’t find the standard you’re looking for? We’re here to help!
