Klarwin laboratory — particle contamination analysis and technical cleanliness determination

Laboratory

SCIENTIFIC & LABORATORY

The Klarwin laboratory integrates precision equipment in a controlled clean-room environment — delivering standardized particle contamination analysis for fluids, components and assembly environments. Every analysis follows documented procedures; testing reports may include classified microscopic images, granulometry, gravimetry and cleanliness codes.

Klarwin cleanliness cabinet — ISO 14644 Level 5 controlled environment

Laboratory Equipment

The cleanliness cabinet creates a strictly controlled environment equivalent to ISO 14644 Level 5 clean room — ensuring secondary (cross-) contamination is minimal and results reflect the true condition of the samples.

  • Cleanliness Cabinet — controlled clean-room space (ISO 14644 Level 5); contaminant extraction from sample surfaces via liquid or gas transfer medium, retained on filtration membrane
  • Jomesa Optical Microscope — automatic identification and counting of metallic, non-metallic and fiber contaminants with dimensions ≥ 5 µm; particle size distribution, automatic cleanliness code reporting, clear images of most relevant contaminants
  • Fluitec MPC Color Spectrophotometer — performs membrane patch colorimetry on oil samples for the early detection and quantitative evaluation of varnish potential
  • Vacuum Filtration System — retains contaminants from liquid samples on membranes for subsequent gravimetric, microscopic or colorimetric evaluation; also used for small-scale industrial filtration process simulations
  • Particle Counters — laser technology or calibrated sieve flow technology; rapid, reliable results for industrial fluid cleanliness class determination
  • Water Sensor (Pall WS19) — determines dissolved water content (below saturation level) in oil

Fluid Particle Contamination Analysis

Cleanliness determination of industrial fluids using standardized procedures. The analysis report is delivered by the laboratory; based on results, the technical department provides interpretation and proposes filtration and separation solutions to keep the process within specifications.

Report deliverables

  • Microscopic images of contaminants — classified by nature: metallic, non-metallic, fibers
  • Granulometry — cleanliness class per ISO 4406 / SAE AS4059F (NAS 1638) and particle distribution
  • Gravimetry according to ISO 4405
  • Dissolved water content in oil
  • Varnish presence in oil according to ASTM-D7843-21
  • Technical interpretation and filtration/separation solution proposals (from technical department)

Fluid particle contamination analysis — microscopic images and cleanliness codes
Component technical cleanliness analysis — ISO 16232 and VDA 19.1

Component Cleanliness Analysis

Technical cleanliness determination of components — primarily automotive — using standardized procedures and industry-specific test protocols.

Report deliverables

  • Granulometry — particle size distribution and cleanliness class per ISO 16232 / VDA 19.1
  • Gravimetry — total particulate mass per component
  • Microscopic images — classified contaminants (metallic, non-metallic, fibers) with dimensions and counts
  • Qualification test — establishes compliant, repeatable test parameters for effective extraction procedure
  • Technical interpretation and improvement recommendations (from technical department)

Environmental Air Cleanliness

Technical cleanliness determination in assembly processes and industrial facilities. Production environment cleanliness is evaluated through multiple analysis types: adhesive membranes (particle traps), plexiglass plates exposed in facilities, and components sampled at intermediate assembly stages.

Report deliverables

  • Particle deposition rate — classified by nature and size, per exposure period and location
  • Illig sedimentation value as per VDA 19.2
  • Microscopic images — identified contaminants with dimensional analysis
  • Technical interpretation and contamination reduction recommendations (from technical department)
Assembly environment air quality analysis — VDA 19.2
Personalized technical cleanliness training programs

Personalized Training

Clear training programs that inspire — for all levels of experience and qualification.

  • Component technical cleanliness (theory + practice) — based on ISO 16232 and VDA 19.1 guidance
  • Technical cleanliness in assembly processes (theory + practice) — based on VDA 19.2 guidance (environment, logistics, personnel and assembly equipment)
  • ISO 17025 requirements application — general competency requirements for testing and calibration laboratories, tailored to the technical cleanliness domain
