Preparing for ISO 9073-2 method A testing: from method to instrument setup

The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) are suitable for compliance with ISO 9073-2 method A, as they meet the required specifications for measuring thickness with precision and consistency.

Confirming the Method Code

Before procurement, it is essential to verify that the selected instrument aligns with the ISO 9073-2 method A standard. This method specifies the procedures for determining the thickness of textile materials, including the use of a calibrated pressing foot and defined load weights. The TNG1089 and TNG1094 models are designed to meet these requirements, ensuring that all measurements are conducted in accordance with the standard. The method code must be cross-referenced with the instrument's specifications to ensure compatibility and accuracy in testing.

Identifying the Required Measuring Range

The measuring range of the instrument is a critical factor in selecting the appropriate model. Both TNG1089 and TNG1094 offer a thickness range of 0.01~25mm, with an optional range of 0.001~25mm. This wide range allows for the testing of various material thicknesses, from very thin fabrics to thicker textiles. The measuring accuracy of 0.01mm ensures that even minor variations in thickness are captured, which is essential for meeting the precision requirements of ISO 9073-2 method A. This specification supports the standard's emphasis on consistent and repeatable measurements.

Checking the Published Specification Table

A thorough review of the published specifications is necessary to ensure that the selected instrument meets all the required parameters. The TNG1089 and TNG1094 models both feature a pressing foot lowering speed of 1.72 mm/s, which is consistent with the standard's recommendation for controlled and uniform pressure application. Additionally, the load weights provided—such as 2cN, 5cN, 10cN, and up to 1000cN—allow for the application of the correct force as specified in the method. The pressing duration options of 10s and 30s also align with the standard's timing requirements, ensuring that the test conditions are standardized across all measurements.

Requesting a Quotation

Once the method code, measuring range, and specifications have been verified, the next step is to request a quotation. This should include details such as the model number, the required specifications, and any additional features needed for compliance with ISO 9073-2 method A. By anchoring each step in the supplied instrument data, the procurement and setup process can be streamlined, ensuring that the selected equipment is both accurate and suitable for the intended testing application.
