Quality

Quality

An ISO quality system and complete in-house test lab enable us to precisely control our process for cleaner products you can depend on.

ISO 9001

Our products are manufactured under the ISO 9001 quality management system. ISO provides a framework to ensure fully conforming products and complete customer satisfaction. We manage the manufacturing process at every step with an emphasis on process interaction and risk assessment. Using “Plan-Do-Check-Act” we stay ahead of problems that impact product performance and cleanliness.

Our product testing methods

Our test methods are based on the Institute of Environmental Sciences and Technology (IEST) standard, IEST-RP-CC004.3: Evaluating Wiping Materials Used in Cleanrooms and Other Controlled Environments.

Testing for Fibers and Particles

Fibers

Wipers are agitated in DIW using a biaxial shaker. The released fibers (> 100µm) are filtered through a membrane and counted microscopically.

IEST-RP-CC004.3
Section 6.1.3 & 6.2.2.2

Particles

Wipers are agitated in DIW using a biaxial shaker. A liquid particle counter measures the particles (≥ 0.5µm) released into the water.

Section 6.1.3 & 6.2.1

Testing for Sorbency

Capacity

A wiper is saturated with DIW and then weighed. Measurements are milliliters of fluid per square meter.

IEST-RP-CC004.3
Section 8.1

Efficiency

A wiper is saturated with DIW and the material is weighed. Measurements are liquid per gram of material.

EST-RP-CC004.3
Section 8.1

Rate

A droplet of DIW is placed on a wiper and the time for the specular reflection to disappear is recorded.

Section 8.2

Testing for NVR and Ions

Non-volatile Residue

NVR is measured using both deionized water and 2-Propanol with results in grams per square meter.

IEST-RP-CC004.3
Section 7.1.2

Ions

Ions are extracted in DIW and measured in ppm with ion chromatography.
