ISO 9073-2 method A: testing scope and instrument selection

Conclusion The TNG1089 and TNG1094 instruments are designed to meet the requirements of ISO 9073-2 method A, ensuring accurate and reliable thickness measurements for textile materials.

Instrument Specifications and Their Relevance to ISO 9073-2 Method A The TNG1089 Digital Thickness Gauge and TNG1094 Fabric Thickness Tester (Gauge) /B are specifically engineered to comply with the ISO 9073-2 method A standard, which outlines procedures for determining the thickness of textile materials. Both instruments share identical specifications, ensuring consistency in testing outcomes. One of the key specifications is the measuring accuracy of 0.01mm, which is essential for achieving the precision required by ISO 9073-2 method A. This level of accuracy ensures that even minor variations in thickness can be detected, which is critical for quality control in textile manufacturing. Another important specification is the lowering speed of the pressing foot at 1.72 mm/s. This controlled speed ensures that the force is applied uniformly and consistently across the sample, reducing the risk of measurement errors due to uneven pressure distribution. The standard requires a specific pressing speed to simulate real-world conditions and ensure reproducibility of results. The area of the pressing foot, which is available in options such as 100mm², 2000mm², 2500mm², and 10000mm², allows for flexibility in testing different types of textile materials. The choice of pressing area is crucial as it affects the pressure applied to the sample, and the standard specifies that the pressing area should be appropriate for the material being tested. The load weights provided by the instruments include options such as 2cN x 2, 5cN x 1, 10cN × 2, 50cN × 2, 100cN x 1, 400cN x 1, and 1000cN × 2. These weights ensure that the instrument can apply the correct force as specified by the standard, which is necessary for obtaining accurate thickness measurements. The pressing duration of 10s or 30s is also a critical specification. The standard requires a specific pressing time to allow the material to settle under the applied force, ensuring that the measurement reflects the true thickness of the material.

Compliance and Testing Procedures The specifications of the TNG1089 and TNG1094 instruments are aligned with the ISO 9073-2 method A standard, ensuring that they can be used effectively in laboratory settings for the accurate measurement of textile thickness. The combination of precise measuring accuracy, controlled pressing speed, and appropriate load weights and pressing duration ensures that the instruments meet the necessary requirements for reliable and repeatable testing.

Summary of Key Specifications The TNG1089 and TNG1094 instruments are equipped with specifications such as measuring accuracy of 0.01mm, lowering speed of 1.72 mm/s, and a range of pressing foot areas and load weights. These features are essential for meeting the requirements of ISO 9073-2 method A, ensuring that the instruments provide accurate and consistent thickness measurements for textile materials.
