Residual Contamination Analysis according to ISO 16232
Testing of Technical Cleanliness according to ISO 16232 for parts, assemblies, and technical components.
What is ISO 16232?
ISO 16232 describes procedures for the extraction, analysis, and evaluation of particulate contamination on components and assemblies.
The standard is used worldwide to assess technical cleanliness and serves, particularly within international supply chains,
as the basis for cleanliness specifications and quality requirements.
Even in small amounts, particulate contamination can impair the function of sensitive components
and reduce the reliability of technical systems.
