AATCC 42 Water resistance Impact penetration test
The AATCC 42 Water Resistance Impact Penetration Test is a critical procedure used to evaluate the water resistance, repellency, and absorbency of textile materials. This test simulates real-world conditions where textiles might be exposed to high-impact water droplets, such as during heavy rain or during accidental spills. The primary purpose of this test is to ensure that the fabric can withstand sudden impacts from water without allowing penetration, which could lead to discomfort for end-users.
During the AATCC 42 test, a series of water droplets are projected onto the specimen at high speed using an impact device. The apparatus consists of a nozzle that delivers water drops with a specified volume and velocity. The specimen is placed in a specific orientation, typically horizontal, to mimic real-world conditions where the fabric might be exposed from above.
The test is designed to measure not only the resistance but also the repellency and absorbency properties of the material. Repellency is crucial for fabrics used in outdoor clothing or rain gear, ensuring that water does not penetrate the fabric surface. Absorbency, on the other hand, is important for materials intended for use as towels or absorbent pads.
The test parameters are meticulously defined to ensure consistency and reliability across different laboratories. The water droplets have a specific volume (typically 50 microliters) and impact velocity (usually 1 meter per second). The specimen must be conditioned according to the requirements of this standard, which includes temperature and humidity control.
The apparatus used in this test is designed to provide accurate measurements. It typically consists of a high-precision impact nozzle, a water supply system with precise flow control, and a collection device for measuring the volume of water that penetrates through the fabric. The test results are reported as the number of impacts required to cause penetration or the total volume of water that has penetrated after a specified number of impacts.
The AATCC 42 test is essential in quality assurance processes, helping manufacturers ensure their products meet the necessary standards for water resistance and repellency. Compliance with this test can enhance consumer confidence by guaranteeing that the product will perform reliably under various conditions.
