ISO 9073: which instrument fits and how to decide

The SmartPull Tensile Tester (Dual Column Type) and Air Permeability Tester are suitable for testing in accordance with ISO 9073, as they provide the necessary specifications to meet the method's requirements for air permeability and tensile strength measurements.

Matching Specifications to ISO 9073 Requirements

ISO 9073 outlines methods for determining the air permeability of textile materials, which is essential for assessing the breathability and performance of fabrics. To support testing to this standard, the Air Permeability Tester (TNG1051) must be capable of measuring air flow through a material under controlled conditions. The TNG1051 offers a test head of 20 cm², which aligns with the standard's requirement for a standardized test area. Additionally, the instrument supports air velocities ranging from 0.6 to 10,000 mm/s, allowing for precise measurement across a wide range of permeability values. These specifications ensure that the tester can accurately replicate the conditions specified in ISO 9073, providing reliable and repeatable results.

Ensuring Accuracy and Precision

The SmartPull Tensile Tester (Dual Column Type) (TNG1019) is designed to measure tensile strength, which is a critical parameter in assessing the mechanical properties of textile materials. The TNG1019 has a test capacity of 1000 kg, which is sufficient for most textile applications, ensuring that the instrument can handle a variety of sample types and thicknesses. The travel accuracy of ≤1% and speed accuracy of ≤1% help ensure that the measurements are both precise and consistent, which is essential for meeting the standards set by ISO 9073. These specifications support the requirement for accurate force measurement and reliable data collection, making the TNG1019 a suitable choice for tensile strength testing.

Customization and Flexibility

Both instruments offer customization options to accommodate different sample thicknesses and test fixtures, which is important for ensuring that the testing process is adaptable to various materials and applications. The TNG1051 allows for measurable sample thicknesses ranging from 0 to 10 mm, with the option to customize for other thicknesses. Similarly, the TNG1019 can be configured with different fixtures to suit specific testing needs. This flexibility ensures that the instruments can be used effectively across a wide range of textile products, supporting the comprehensive testing requirements of ISO 9073. By providing these customizable features, the instruments enhance their usability and reliability in laboratory settings.
