The GSFCC Laboratory is an independent testing facility for cleanroom materials (Gloves, Wipers, Disposable Apparel, Reusable Garments, Papers, Mops, Finger Cots).

At Valutek we provide our clients the opportunity to test cleanroom consumables, why? The purpose is to validate vendor’s quality, and to insure the garments being used meets the faculties cleanroom specifications. The GSFCC Laboratory testing services will provide comparison analysis on your incumbent product versus other product options. All testing done per IEST/ASTM documented test methods


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


- Physical Properties (Dimension, Basis weight etc.)

- Microscope Examination

- Sorbency (Capacity & Rate)

- Particle Counts (LPC & APC)


- Physical Properties (Thickness, weight etc.)

- Particle Counts

- Microscope Examination

Reusable Garments

- Airborne Particle Counts

Disposable Apparel

- Airborne Particle Counts

Cleaning Material

- Particle Counts

ESD Testing

-Surface Resistivity


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

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.

Stereomicroscope: Provides both 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), surface to ground (RTG), and surface resistivity in complete accordance with EOS/ESD standard.

All GSFCC testing services are per IEST 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, and cuff, palm, and finger thickness.
- IEST-RP-CC-0043.3 (for absorbency) test method for intrinsic, extrinsic sorbency, 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).
