ISO 9073-2 method A tester models and their published ranges

The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) both meet the requirements of ISO 9073-2 method A for measuring fabric thickness, but they differ in design and application.

Instrument Specifications and Standard Compliance

Both the TNG1089 and TNG1094 are designed to conform to ISO 9073-2 method A, which specifies the procedures for determining the thickness of textile materials. The TNG1089, known as the Digital Thickness Gauge, offers a range of thickness measurement from 0.01 to 25 mm, with an optional range extending to 0.001 mm. This wide range ensures that the instrument can accommodate various fabric types and thickness levels, making it suitable for both fine and thick materials. The measuring accuracy of 0.01 mm is crucial for precise thickness determination, aligning with the standard's requirement for reliable and repeatable measurements.

The TNG1094, or Fabric Thickness Tester (Gauge) /B, also provides a thickness range of 0.01 to 25 mm, with the same optional extension to 0.001 mm. This similarity in range ensures that both instruments can be used for a broad spectrum of testing scenarios. The measuring accuracy of 0.01 mm is consistent with the TNG1089, supporting the standard's emphasis on precision. The pressing foot lowering speed of 1.72 mm/s is another shared specification, ensuring uniform pressure application during testing, which is essential for accurate results as per ISO 9073-2 method A.

Pressing Foot Area and Load Weight

The pressing foot area options for both instruments include 100mm², 2000mm², 2500mm², and 10000mm². This variety allows users to select the appropriate area based on the material's characteristics and the required test conditions. A smaller area is typically used for finer materials to ensure accurate measurement, while larger areas are suitable for thicker or more robust fabrics. 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 load weights provide flexibility in applying the correct pressure for different fabric types, ensuring compliance with the standard's specifications for consistent and reliable testing.

Pressing Duration and Application

Both instruments offer pressing durations of 10 seconds and 30 seconds. This feature allows for testing under different conditions, such as short-term compression or extended pressure application, depending on the specific requirements of the test. The ability to adjust pressing duration ensures that the instruments can be adapted to various testing protocols, enhancing their versatility in laboratory settings. The combination of these specifications supports the ISO 9073-2 method A by providing the necessary parameters for accurate and standardized thickness measurement.
