ISO 9073 tester models and their published ranges

The SmartPull Tensile Tester (Dual Column Type) and Air Permeability Tester are both suitable for testing in accordance with ISO 9073, but they serve different testing purposes and have distinct specifications that support their respective applications.

Air Permeability Testing and ISO 9073 Compliance

The Air Permeability Tester (TNG1051) is specifically designed for air permeability testing, which is a key requirement under ISO 9073. This standard covers the measurement of air permeability of nonwoven fabrics and other porous materials. The TNG1051 offers a wide range of measurement units, including mm/s, m/s, and l/m²/s, which allows for compatibility with various testing protocols and data interpretation methods. The test mode is set to automatic, ensuring consistent and repeatable results, which is essential for compliance with ISO 9073. Additionally, the test head size of 20 cm² is standard, providing a uniform testing area that minimizes variability in measurements. The air velocity range of 0.6 to 10,000 mm/s (20 cm²) supports a broad spectrum of material types, from low to high permeability, ensuring accurate results across different applications.

Tensile Strength Testing and ISO 9073 Compliance

The SmartPull Tensile Tester (Dual Column Type) (TNG1019) is designed for tensile strength testing, which is also covered under ISO 9073 for certain material types. This instrument has a test capacity of 1000 kg, making it suitable for testing materials with high tensile strength requirements. The travel accuracy of ≤1% ensures that the movement of the testing jaws is precise, which is critical for obtaining reliable force-displacement data. The travel speed range of 1 mm/min to 500 mm/min allows for both slow and fast testing cycles, accommodating different testing standards and material behaviors. The speed accuracy of ≤1% further enhances the reliability of the results, ensuring that the measured force is consistent with actual material properties.

Comparison of Specifications for ISO 9073 Compliance

Both instruments are designed to meet the requirements of ISO 9073, but they focus on different aspects of material testing. The TNG1051's wide range of measurement units and air velocity settings make it ideal for air permeability testing, while the TNG1019's high test capacity and precise travel accuracy are better suited for tensile strength testing. These specifications ensure that each instrument can provide accurate, repeatable, and standardized results, which are essential for compliance with ISO 9073. The choice between the two depends on the specific testing needs of the material being evaluated.
