GB/T 24218.2 Method A tester models and their published ranges

The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) are both suitable for testing in accordance with GB/T 24218.2 Method A, but they differ in design and application.

Specifications and Testing Capabilities

Both instruments are designed for fineness, thickness, length, and density testing, and they share several key specifications that align with the requirements of GB/T 24218.2 Method A. The measuring accuracy of both models is specified as 0.01mm, which is critical for ensuring precise thickness measurements required by the standard. This level of accuracy allows for reliable data collection, essential for compliance with the standard's stringent requirements.

The lowering speed of the pressing foot is set at 1.72 mm/s for both models. This controlled speed ensures consistent pressure application during testing, minimizing variability in results. The standard GB/T 24218.2 Method A emphasizes the importance of uniform pressure application to achieve accurate and repeatable measurements.

Pressing Foot Area and Load Weight

The pressing foot area options for both models include 100mm², 2000mm², 2500mm², and 10000mm², providing flexibility for different fabric types and testing scenarios. A smaller pressing foot area is suitable for thin or delicate materials, while a larger area is appropriate for thicker or more robust fabrics. This versatility supports the standard's requirement for testing a wide range of textile materials.

The load weight options for both models are 2cN x 2, 5cN x 1, 10cN × 2, 50cN × 2, 100cN x 1, 400cN x 1, and 1000cN × 2. These multiple load settings allow users to select the appropriate pressure for different fabric types, ensuring that the test conditions match the material being evaluated. The standard GB/T 24218.2 Method A requires specific load applications depending on the material's thickness and structure, and these load options provide the necessary flexibility.

Pressing Duration and Standard Compliance

Both models offer pressing durations of 10s and 30s, which are essential for ensuring that the material is fully compressed under the specified load. The standard GB/T 24218.2 Method A requires a defined pressing time to allow for complete deformation of the material, ensuring consistent and accurate thickness measurements. The ability to select between 10s and 30s provides users with the option to adjust the test duration based on the material's properties and testing requirements.

In summary, the Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) both meet the specifications required by GB/T 24218.2 Method A, offering precise measurements, controlled pressure application, and flexible load and duration settings. While they share many common features, their design and application may vary depending on the specific testing needs of the user.
