Cleanliness Verification Testing

A critical step in the Precision Cleaning process is Cleanliness Verification Testing, which ensures that cleaned parts and components meet the determined cleanliness level as noted in the specification. Our proprietary process, equipment and facility allows us to attain cleanliness levels in the range of IEST 1246 D Level 50A to IEST 1246 Levels A/10 and A/20.

To ensure cleanliness, we verify levels using optical particle counters and gravimetric NVR equipment, photoionization detectors for solvent detection and dryness verification and digital dew-point meters for water dryness verification. Additionally, we use fume hoods, laminar flow hoods, and a complete wet chemistry laboratory for research and development which complements the cleaning and testing services.

Whether cleaning and confirming particulate levels, non-volatile residue levels, or other contamination limits, Astro Pak is expertly equipped to meet your precision cleaning and verification needs. We also routinely consult and perform projects that require highest cleanliness levels. 

Cleaning Verification Testing

Particle Count: measures the numbers and sizes of particles remaining on the surface.

Non-Volatile Residue (NVR): The measurement of residues, which are mostly oils and greases, which remain on the cleaned surface.

Total Filterable Solids (TFS): Similar to a Particle Count, we collectively weigh to determine the total mass using the same precision analytical microbalance used in the NVR measurement.

Solvent Removal: This is the assurance that no solvent remains behind after the cleaning and contaminant extraction processes are completed.

Dewpoint: This measurement is capable of detecting trace amounts of moisture and quantifying them, allowing us to determine the exact state of dryness of the hardware, assuring that no excess moisture remains.

Trust the Experts

Astro Pak Corporation has over 50 years of experience in cleaning and packaging precision clean hardware. Whether its small components or huge vessels we can clean it all! Our packaging services also meet the requirements of literally hundreds of industry specifications. This includes aerospace contractors, ULA, NASA, the Department of Defense, and many private industries and organizations.

To ensure quality packaging of hardware, all plastic films are precision cleaned, tested for contaminants and certified prior to use. Our material is capable of protecting parts during transportation and handling, resistant to punctures and tearing. It is also free from generating contaminants such as particles from friction between the material itself and the part inside.

The flagship location for all cleanliness testing services in in our California Cleanroom. Our CA location is ISO 9001:2008/AS9100 – Class 5 (class 100) and Class 6 (Class 1000) cleanrooms. We also offer some testing services in our newly acquired location in Florida, called Chemko.  All hardware and components that enter our cleanroom include real time electronic tracking to keep customers better informed on the status of order. In addition to Cleaning and Packaging, we also allow customers to come onsite and assemble their own parts after cleaning.

Astro Pak commits to providing customers with the level of excellence they expect and deserve by:

  • Advanced Chemistry & Process Technology
  • Highly Trained Personnel delivering superior consulting services
  • Rapid Response
