ASTM D76 Standard Test Method Used In Tensile Strength Tester For Textile

The ASTM D76 standard test method includes the operating features of the tensile strength tester to determine the force-elongation properties of the textile materials. The test method covers three types of machines that include Constant-Rate-of-Extension (CRE), Constant-Rate-of-Traverse (CRT), and Constant-Rate-of-Loading (CRL).

• Always verify the testing machines calibration especially when using in different locations to ensure that the machines are still complying with the specified tolerance.
• Use motor-driven machine in place of manually driven machine.
• Never use constant-rate-of-traverse type machines for measuring forces below fifty times their resolution.
• Ensure machines are equipped with a device for measuring force.
• Test methods must include clamping or holding devices.
• As per the individual standards, indicated force, nominal gage length, maximum acceptable error, and moving clamp must be within the tolerances.
• Ensure testing methods of recorded clamp displacement, recorded elongation, and nominal gage length conforms to procedures as per specification.

Importance of Accurate Testing in Textile Quality Control

In addition to the basic requirements of the ASTM D76 tensile test, it is essential to assess the environmental factors such as humidity and temperature, which may influence the tensile properties of fabrics. Regular maintenance and timely calibration not only increase the accuracy of textile strength testing machine results but also ensure compliance with ASTM standards. Testing personnel must be adequately trained in force-elongation testing for textile materials, especially when working with critical or high-performance applications such as technical fabrics or composites. Incorporating fabric strength measurement tools into the quality control workflow enhances the reliability and consistency of results.

Presto offers the high quality of Tensile Strength Test for Textile build with heavy mild steel. The machine is available in three models; digital model, digital cum computerized (eco) wintest model, Zeus ultimo. These models are capable of determining the tensile strength of the textile materials. Tensile strength is significant for the textile industries to determine the actual strength and durability of the textile materials. The machine operation is based on CRT principal. The device effectively determines the breaking strength of the raw materials.

The ASTM D76 standard is up to date test method used for determining the tensile properties of the materials.
