ISO 9073 testing: the specifications that decide the fit

The Air Permeability Tester (TNG1051) and SmartPull Tensile Tester (TNG1019) are essential instruments for conducting tests in accordance with ISO 9073, which outlines methods for determining air permeability and mechanical properties of materials.

Understanding Specification Tables for ISO 9073 Compliance

Reading a specification table is crucial when selecting instruments that meet the requirements of ISO 9073. For instance, the TNG1051 Air Permeability Tester specifies "Measurement units" as including "mm/s, m/s, l/m²/s, ft³/min/ft², cfm, cm³/s/cm², l/s/cm², l/m²/min 1/dm²/min,l/min, m³/min, dm³/s m³/s/m², m³/min/m², m³/h/m², ft³/s/ft²". This wide range of units ensures that the tester can accommodate various international standards and user preferences, allowing for accurate and consistent measurements across different testing environments. Another key specification is "Air velocity," which is set at "0.6~10,000 mm/s (20 cm²)". This range is critical because it enables the instrument to measure air permeability across a broad spectrum of material types, from highly permeable fabrics to dense nonwovens, ensuring that the test results are relevant and applicable to the specific material under evaluation.

Ensuring Precision with the SmartPull Tensile Tester

The SmartPull Tensile Tester (TNG1019) is designed for mechanical testing and includes specifications that directly support ISO 9073 requirements. One important specification is "Test capacity," which is rated at "1000 kg". This high capacity ensures that the instrument can handle a wide range of material thicknesses and strengths, making it suitable for testing both thin and thick samples. Additionally, the "Travel accuracy" is specified as "≤1%", which is vital for maintaining the precision of the test results. This level of accuracy is necessary to ensure that the force applied during the test is consistent and that the measurements are reliable, thus supporting the reproducibility and validity of the test results in compliance with ISO 9073.

Customization and Flexibility for Diverse Testing Needs

Both instruments offer customization options that enhance their applicability to ISO 9073 testing. The TNG1051 specifies a "Measurable sample thickness range" of "0~10 mm (other thicknesses and fixtures can be customized)". This flexibility allows users to adapt the instrument to their specific testing requirements, whether they are working with thin films or thicker materials. Similarly, the TNG1019 provides a "Max Travel" of "900mm (without fixture)", which is essential for testing materials that require a longer travel distance to achieve accurate force measurements. These customizable features ensure that the instruments can be tailored to meet the diverse needs of testing environments while maintaining compliance with ISO 9073 standards.
