AATCC 119 testing: the specifications that decide the fit

The Universal Wear Tester (TNG1003) is a critical instrument for conducting abrasion, pilling, and snagging tests in compliance with AATCC 119, ensuring accurate and repeatable results through its precise specifications and versatile accessories.

Understanding Specification Tables

When reviewing a specification table for a testing instrument, it is essential to identify key parameters that directly influence the accuracy and reliability of test results. For the Universal Wear Tester (TNG1003), two important specifications are the Rotation Speed 100rpm (adjustable) and the Measuring Range 25mm. The rotation speed of 100rpm is a fundamental parameter that determines the rate at which the test specimen is subjected to abrasive action. This speed is adjustable, allowing users to tailor the test conditions to match the specific requirements of the standard or the material being tested. By maintaining a consistent rotational speed, the instrument ensures that the test results are not influenced by variations in mechanical movement, thus enhancing the reproducibility of the test.

The Measuring Range 25mm refers to the maximum distance over which the wear depth can be measured. This specification is crucial for assessing the extent of material degradation during the test. A measuring range of 25mm allows for the detection of even minor changes in the surface of the test specimen, which is particularly important when evaluating the durability of textiles or other materials under abrasive conditions. This range ensures that the instrument can accurately capture the wear depth, providing reliable data for compliance with AATCC 1109.

Compliance with AATCC 119

The Universal Wear Tester (TNG1003) is designed to meet the requirements of AATCC 119, which outlines the procedures for evaluating the abrasion resistance of textile materials. The instrument's ability to accommodate various abrasion kits, such as Depth Abrasion kits, Surface Abrasion kits, and Flex Abrasion kits, ensures that it can perform a wide range of tests as specified by the standard. These kits are specifically engineered to simulate different types of wear that textiles may encounter in real-world conditions, such as friction from clothing, environmental exposure, and mechanical stress.

Additionally, the TNG1003 supports optional accessories like the frosting attachment and edge and fold abrasion clamp, which enhance the versatility of the instrument. These accessories allow for more precise and detailed testing, ensuring that the results are both accurate and representative of the material's performance under various conditions. The inclusion of photographic standards for ASTM D 3514 further supports the instrument's compliance with industry standards, providing a visual reference for consistent test setup and evaluation.

Accessories and Standards

The Universal Wear Tester (TNG1003) is compatible with a variety of abrasive materials, including the abrasive ‘0’ 50 yd/ roll, abrasive ‘600A’ 50 yd/ roll, and abrasive ‘320J’ 50 yd/ roll. These abrasives are selected based on the specific test requirements and the type of material being evaluated. The availability of these abrasives ensures that the instrument can perform tests in accordance with multiple standards, including ASTM D3514, ASTM D3885, ASTM D3886, AATCC 119, and AATCC 120. This versatility makes the TNG1003 an essential tool for laboratories requiring comprehensive testing capabilities.
