Preparing for ISO 9073 testing: from method to instrument setup

The SmartPull Tensile Tester (TNG1019) and Air Permeability Tester (TNG1051) are suitable for compliance with ISO 9073, providing accurate and repeatable measurements for air permeability and tensile strength testing.

Confirm the Method Code

Before procurement, verify that the testing method aligns with ISO 9073. This standard specifies procedures for determining air permeability of porous materials, including textiles, nonwovens, and films. The TNG1051 Air Permeability Tester is specifically designed for this purpose, offering a range of measurement units such as mm/s, m/s, and l/m²/s, which are directly referenced in ISO 9073. The test mode is automatic, ensuring consistent and reliable results, crucial for meeting the standard’s requirements.

Identify the Required Measuring Range

Select the instrument based on the required measuring range. The TNG1051 supports air velocity measurements from 0.6 to 10,000 mm/s (20 cm²), which is essential for testing materials with varying permeability levels. This wide range ensures that the instrument can accommodate different sample types and thicknesses, from 0 to 10 mm, with the option for custom fixtures. The TNG1019 SmartPull Tensile Tester, on the other hand, is ideal for tensile and bursting strength tests, with a test capacity of 1000 kg and a test force range of 0.5% to 100%FS, ensuring accurate force measurement across a broad spectrum of materials.

Check the Published Specification Table

Review the published specifications to ensure the instrument meets the necessary criteria. The TNG1051 features a test pressure range of 10 to 2,500 Pa, which is critical for simulating real-world conditions during air permeability testing. The travel accuracy and speed accuracy of the TNG1019, both ≤1%, help ensure that the test results are precise and repeatable, aligning with the strict requirements of ISO 9073. These specifications are essential for ensuring that the testing process is both accurate and compliant with the standard.

Request a Quotation

Once the method code, measuring range, and specifications are confirmed, request a quotation from the manufacturer. Ensure that the quotation includes the model numbers TNG1051 and TNG1019, along with the relevant specifications. This step ensures that the procurement process is aligned with the standard and that the selected instruments are capable of delivering the required test results. By following this checklist, you can confidently select and set up the appropriate instruments for ISO 9073 compliance.
