Independent Testing

Independent Testing for Cleanroom Consumables 

At Valutek we provide our clients the opportunity to test cleanroom consumables, why?

The purpose of independent testing is to validate the vendor’s quality and to insure the garments being used meets the faculty's cleanroom specifications. The testing services will provide a comparative analysis of your incumbent product versus other product options. All testings are done per IEST/ASTM documented test methods.


Valutek will test your cleanroom materials and determine if they meet/-exceed their published manufacture specifications. Currently, Valutek provides the following test services in the form of product testing reports and comparison reports:


  • Physical Properties (Thickness, weight etc.)
  • Particle Counts
  • Microscope Examination
  • Physical Properties (Dimension, Basis weight, etc.)
  • Microscope Examination
  • Sorbency (Capacity & Rate)
  • Particle Counts (LPC & APC)
  • Airborne Particle Counts
  • Disposable Apparel
  • Airborne Particle Counts
  • Cleaning Material
  • Particle Counts
  • Surface Resistivity


Helmke Yeich Tumble Drum

Air Particle Count (APC) Testing of garments, wipers, gloves, and other clean room-ready products to determine the number and size of particles released.


Scanning Electronic Microscope

To produce images of a sample by scanning it with a focused beam of electrons. For particle characterization and material identification.

Scanning Electronic Microscope-2

Stereo Microscope

Provides excellent optical performance, such as high-magnification, high-zoom ratio and high-resolution images, and advanced operability.


Digital Surface Resistance Meter

To measure resistance between two points (RTT), the surface to the ground (RTG), and surface resistivity in complete accordance with EOS/ESD standard.

Digital Surface Resistance Meter

All Valutek testing services are per IEST's recommended practices and ASTM test methods.

IEST Standards and Recommended Practices (RPs) provide standardized procedures based upon peer-approved applications of environmental technology. (i.e. IEST-RP-CC004: Evaluating Wiping Materials.)

ASTM's laboratory testing standards are instrumental in specifying the standard dimensions, design, and make of the various equipment and instruments used in the laboratory for scientific experiments and procedures. (i.e. ASTM D3767: Standard Practice for Rubber—Measurement of Dimensions)
We test for physical properties using the following methods:

  • TAPP T-410 test methods for Material, cutting/edge basis weight, and Dimensions.
  • ASTM D3767 test methods for palm width, length, weight, area, cuff, palm, and finger thickness.
  • IEST-RP-CC-0043.3 (for absorbency) test method for intrinsic, extrinsic absorbency, and the sorption rate.
  • IEST-RP-CC-005.4 test methods for Air Particle Count using the Helmke Drum, and a biaxial shake for fiber count.
  • Non Volatile Residue (NVR) using test methods IEST-RP-CC-005.4 for the DI Extraction, IPA Extraction, DI Extractable matter percent, and IPA Extractable Matter Percent.
  • ESD In-Use Resistance Testing using ANSI/ESD SP15.1-2011 for Surface Resistance, Volume Resistance, Point-to-point Resistance, and Constant Area Force Electrode (CAFÉ).
