GB/T 24218.2 Method A: testing scope and instrument selection

Compliance with GB/T 24218.2 Method A The instruments TNG1089 and TNG1094 are specifically designed to meet the requirements of GB/T 24218.2 Method A, which outlines the procedures for determining the thickness of nonwoven fabric. These instruments ensure accurate and repeatable measurements, essential for quality control in textile manufacturing.

Instrument Specifications and Their Relevance to GB/T 24218.2 Method A The Digital Thickness Gauge (model TNG1089) and the Fabric Thickness Tester (Gauge) /B (model TNG1094) both feature a measuring accuracy of 0.01mm. This level of precision is critical for compliance with GB/T 24218.2 Method A, as it allows for the detection of minor variations in fabric thickness that could affect performance and quality. Additionally, both instruments offer a range of thickness measurement from 0.01 to 25mm, with an optional range extending down to 0.001mm. This wide range ensures that the instruments can be used for a variety of fabric types, from thin, delicate materials to thicker, more robust textiles. The pressing foot lowering speed of 1.72 mm/s is another important specification. This controlled speed ensures that the measurement process is consistent and minimizes the risk of deformation or damage to the fabric during testing. The pressing foot area options—100mm², 2000mm², 2500mm², and 10000mm²—allow for the selection of the appropriate contact area based on the fabric's thickness and density. This flexibility is crucial for obtaining accurate and representative measurements according to the standard.

Load Weight and Pressing Duration for Accurate Testing Both models provide a range of load weights, including 2cN, 5cN, 10cN, 50cN, 100cN, 400cN, and 1000cN. This variety enables users to select the optimal load for different fabric types, ensuring that the measurement reflects the actual thickness without over- or under-compression. The pressing duration options of 10 seconds and 30 seconds allow for the adjustment of measurement time based on the fabric's characteristics, ensuring that the test results are reliable and consistent with the requirements of GB/T 24218.2 Method A. These specifications collectively support the testing procedures outlined in GB/T 24218.2 Method A, ensuring that the instruments provide accurate, repeatable, and standardized results.
