SDL Atlas introduced its Impact Penetration Tester, designed to satisfy AATCC Test Method 42: Water Resistance: Impact Penetration. Originally developed to predict rain penetration, AATCC TM 42 has been adopted by the medical industry as a measure of liquid barrier performance for personal protective equipment (PPE).
With a frame made of high-grade stainless steel, the instrument also has a small blade inside the funnel to allow smooth water flow without swirling, clamps to hold the sample in place with a weighted bottom clamp to hold the sample flat, and an integrated drip catcher for any leftover water from the previous test. An air-bubble on the base show when the instrument is properly leveled. SDL Atlas also supplies the specialized 6” x 9” Blotting Paper the test requires.
