ISO 5084: which instrument fits and how to decide

The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) are suitable for testing in accordance with ISO 5084 due to their precise measurement capabilities and adjustable parameters that align with the standard's requirements.

Matching Specifications to ISO 5084

ISO 5084 outlines the procedures for determining the thickness of textile materials using a mechanical method. To ensure accurate and repeatable results, the instrument must provide precise measurements, adjustable pressing foot areas, and controlled pressing duration. The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) both meet these criteria through their specified features.

The measuring accuracy of 0.01mm is critical for ISO 5084, as it ensures that the thickness measurements are precise enough to detect small variations in material thickness. This level of accuracy is essential for quality control and compliance with industry standards. Both instruments have this specification, which supports the standard's requirement for reliable and consistent data.

Another key specification is the area of the pressing foot, which affects how the material is compressed during testing. The TNG1089 and TNG1094 offer multiple pressing foot areas, including 100mm², 2000mm², 2500mm², and 10000mm². This flexibility allows users to select the appropriate area based on the material type and thickness, ensuring that the test conditions are representative of real-world usage. The ability to adjust the pressing foot area is a direct requirement of ISO 5084, which mandates that the test setup must be suitable for the material being evaluated.

Load Weight and Pressing Duration

The load weight options available on both instruments—ranging from 2cN to 1000cN—allow for precise control over the pressure applied to the material. This is important because the standard specifies that the load should be sufficient to compress the material without causing deformation. The TNG1089 and TNG1094 provide multiple load weight settings, ensuring that the test can be adapted to different material types and thicknesses.

Additionally, the pressing duration of 10 seconds or 30 seconds is another critical parameter. ISO 5084 requires that the pressing duration be consistent to ensure that the results are comparable across different tests. Both instruments offer these options, allowing users to select the appropriate duration based on the material's characteristics and the desired test outcome.

Conclusion and Selection Decision

When selecting an instrument for testing in accordance with ISO 5084, it is essential to focus on specifications such as measuring accuracy, pressing foot area, load weight, and pressing duration. The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) both meet these requirements, making them suitable choices for compliance with the standard. Their adjustable parameters and precise measurement capabilities ensure that the test results are reliable and consistent, supporting the quality and accuracy needed for ISO 5084 compliance.
