GB/T24218.2 Method A: testing scope and instrument selection

Compliance with GB/T24218.2 Method A The instruments TNG1089 and TNG1094 are specifically designed to meet the requirements of GB/T24218.2 Method A, which outlines the procedures for determining the thickness of nonwoven fabrics. These instruments ensure accurate and reliable measurements, supporting compliance with the standard's specifications.

Instrument Specifications and Their Relevance to GB/T24218.2 Method A The Digital Thickness Gauge (model no. TNG1089) and the Fabric Thickness Tester (Gauge) /B (model no. TNG1094) are both equipped with a measuring accuracy of 0.01mm. This level of precision is essential for GB/T24218.2 Method A, which requires precise thickness measurements to assess the material's properties accurately. Additionally, the lowering speed of the pressing foot is set at 1.72 mm/s, ensuring consistent and controlled application of pressure during the measurement process. This specification supports the standard's requirement for uniform pressure application, which is critical for obtaining reliable and repeatable results. The pressing foot area options, including 100mm², 2000mm², 2500mm², and 10000mm², allow for flexibility in testing different fabric types and thicknesses. This adaptability is important for GB/T24218.2 Method A, which may require varying contact areas depending on the test specimen. The load weights available on both instruments, such as 2cN, 5cN, 10cN, and up to 1000cN, provide the necessary force to compress the fabric sample without causing deformation. This range of load weights ensures that the instruments can accommodate various fabric densities and thicknesses as specified by the standard.

Testing Procedures and Instrument Capabilities The pressing duration options of 10s and 30s are designed to meet the time constraints outlined in GB/T24218.2 Method A. These durations allow for the measurement of thickness under controlled conditions, ensuring that the results are both accurate and representative of the material's true properties. The combination of these specifications—measuring accuracy, pressing speed, pressing foot area, and load weights—ensures that the instruments can perform the required tests with high precision and reliability.

Conclusion The TNG1089 and TNG1094 instruments are specifically designed to meet the requirements of GB/T24218.2 Method A, providing accurate and reliable thickness measurements through their precise specifications. These instruments support testing to the standard by offering controlled pressure application, consistent measurement accuracy, and adaptable testing parameters.
