![]() ![]() “15” = Contamination Level = number of particles allowed for the size class preceding the Contamination Level number. ![]() “C-E” means that size classes C (15µm-25µm), D (25µm-50µm), and E (50µm-100µm) are combined so that particles from 15µm-100µm essentially make up a size class named “C-E.” The most common ISO 16232 cleanliness codes display Standard Area based spec Limits designated by the “A” in front of the parentheses. “A” = Area = Standard Area = 1,000cm 2 (defining cleanliness per a Standard Area allows you to directly compare cleanliness of parts of differing sizes) It could have either a “V” for volume or a “N” for numbers of particles per part instead of an “A” for Standard Area. So what does that ISO 16232 cleanliness code mean? Test laboratory accredited in accordance with DIN EN ISO/IEC 17025, class 8 cleanroom, analyses according to VDA 19/19.1/19.2, ISO 16232, customer standards and specifications.So what does that strange code CCC = A(C-E15/F-G10/H-I4/J-K00) mean? You do some research and discover the cleanliness limits listed on the print or in a table are an ISO 16232 cleanliness code which is totally based on particle count rather than mass. We analyse your assembly environment or individual stations using particle traps for environmental monitoring.ĪCCREDITED TEST LABORATORY FOR CLEANLINESS ANALYSES AND QUALITY ASSURANCE: More analysis options, more comprehensive results and sound information on the particles analysed. Test ink, fluorescence measurement, gas chromatography with flame ionisation detector (GC-FID), RAMAN and FT-IR spectroscopy and gravimetric assessmentįor very small components up to large assemblies, in future up to 1,000 kg.įor inorganic and organic particles and contamination on function-related parts, assemblies, systems and fluids.ĬOMPETITIVE ADVANTAGE OF CORRELATIVE PARTICLE ANALYSIS: QUALITATIVE AND QUANTITATIVE INVESTIGATION OF CONTAMINATING FILMS ON SURFACES: We also support you with particle monitoring in your production and assembly environment.ĮXTRACTION AND ANALYSIS METHODS FOR RESIDUAL DIRT ANALYSIS:Įxtraction with and without ultrasound, gravimetry, light and scanning electron microscopy as well as RAMAN and FT-IR spectroscopy For you, we take over the check on the surface cleanliness of very small function-related components, entire assemblies and systems up to 1,000 kg as well as a very wide range of fluids. In our excellently equipped cleanliness laboratories we acquire, extract and analyse particulate contamination and contaminating films. RESIDUAL DIRT ANALYSIS AND TECHNICAL CLEANLINESS VERIFICATION IN ACCORDANCE WITH VDA 19/19.1 Our accredited laboratory and our multi-faceted cleanliness analyses help you as a manufacturer to guarantee the function, durability and quality, as well as the trouble-free manufacture of your products. Huge technical advances mean that consistent compliance with cleanliness requirements is no longer just a voluntary exercise, instead it has become mandatory. Technical cleanliness verification is an important quality feature these days, among others in the automotive industry, the supplier industry, medical technology, the electrical engineering industry and the new sector of e-mobility. QUALITY ADVANTAGE DUE TO TECHNICAL CLEANLINESS VERIFICATION
