What is the Maximum and Minimum Diameter of Holding the Specimen for Torque Test?
  • Gaurav Malhotra

The maximum and minimum diameter for holding a specimen during a torque test depends on the design and specifications of the torque testing equipment being used. In torque testing, the specimen is subjected to rotational force to assess its resistance to twisting or turning. The fixture or grip that holds the specimen plays a crucial role in ensuring accurate and reliable torque measurements.

With Presto digital torque testing equipment with printer, manufacturers of the bottle industry can easily conduct torque tests on the materials and ensure that accurate products will be delivered to the customers. In this Blog, we will discuss the maximum and minimum diameter that will be required for holding the specimen accurately for the torque test.

Understanding the Concept of Maximum and Minimum Diameter for Holding Specimens in Torque Testing

We all know that bottle cap torque testing is an important aspect of quality assurance for the bottle testing industry. With the Presto torque machine for bottle caps testing, manufacturers can easily measure the rotational force that will be required to twist and turn a specimen until it breaks. This will help the manufacturers in determining the strength and durability of materials.

One essential factor that will help the users in influencing the reliability and accuracy of torque testing is the maximum and minimum diameter, for holding the testing specimen. The diameter of torque refers to the size and thickness of the specimen being used and tested.

Various torque testers have different diameters for holding and placing the specimen. Whenever the user conducts the test it is important for the manufacturers to hold the testing specimen tightly so that the specimen will be held at their place without any slippage.

For the Presto torque tester for bottle caps and jars, manufacturers will get the minimum diameter for specimen holding i.e. 30 mm and the maximum diameter for specimen holding i.e. 110 mm.

This torque tester for bottle caps and jars will help the manufacturers ensure the accuracy and reliability of lab testing results.

Impact of Incorrect Diameter on Torque Test Results

The Presto digital torque tester is one of the widely used laboratory testing equipment that will help the manufacturers conduct torque tests on the bottles.

The maximum and minimum diameter of a specimen is a crucial factor in torque testing measurement, as it directly affects the accuracy and reliability of the lab test results. The incorrect determination of these diameters can have significant impacts on the performance evaluation and quality control processes for various products.

One of the major influences that incorrect maximum and minimum diameters can have on torque test results is an inaccurate measurement. If the maximum and minimum diameters are not accurately determined, it can lead to errors in measuring the applied torque force. This can result in misleading data, causing potential issues with product design, functionality, and safety.

With digital torque machines for bottle caps, manufacturers can easily and accurately determine the torque capacity of the machine and ensure that the right torque value of the specimen will be determined.

This high-quality bottle testing instrument can save 9 sample readings with digital readout and help users monitor the peak load facility of the specimen and get highly accurate lab testing results.
