How to Prepare the Testing Specimen for the Tensile Strength Test?

The tensile strength of materials plays a major role in evaluating product quality. The strength of the material will depend on several factors that can affect its quality as well as its life. Thus, to examine the tensile strength of materials, you can easily make use of the Presto tensile strength tester. Presto is considered to be Asia’s best testing instruments provider and helps you to assess the quality of your products.

This testing instrument is based on the constant rate of traverse principle. It has been equipped with an upper and lower jaw to hold the specimen firmly. Let’s find out some more information about this testing machine and a few easy steps to prepare the testing specimen.

What is tensile strength and how you can measure it with a tensile strength tester?

The tensile strength of the materials is a unique property of materials that will help you to determine the maximum load a material can withstand without getting fractured. When the metal or other similar material will be exposed under high pressure then it will get break down. This will affect its quality. The material with high tensile strength is more durable than those with low tensile strength.

Thus, to examine this strength, Presto tensile strength tester plays a major role. The tensile strength tester digital cum computerized model will let you assess the quality of materials and finished products. This highly versatile laboratory testing equipment has been used with the purpose of testing and analysis.

The instrument is provided with a limit switch which acts as a safety feature for the machine and limits the movement of grips of the machine. The outer body of this lab testing equipment has been fabricated with mild steel which is duly powder coated. The limit switch provided with the instrument is one of the best safety features that prevent the collision of grips.

Here we have discussed the features and technical specifications of the digital cum computerized model of this lab testing equipment.

Features of Tensile strength tester digital cum computerized model

• High testing range
• Vice-type clamping grips for firm gripping of test specimen (standard grip).
• Advanced peak load indicator for accurate readout and storage of test results.
• Limit switches protection for the protection of grips and the machine.
• Powder-coated body with corrosion resistance.
• Available in different capacities as per client’s requirements.

These are the features you will get with the use of digital cum computerized model. Now, let us focus on its technical specifications.

Now, let us focus on how you can easily prepare the testing specimen accurately with the help of this testing instrument.

Steps to prepare the testing specimen in tensile strength tester

Whenever you are ready to conduct the test with the help of a tensile strength testing machine, you can easily prepare the testing specimen first. Thus, we have listed some easy steps to prepare the testing specimen with ease.

Steps to prepare dumbbell shape specimen

• Take a sample strip from the material you want to test.
• Place it on the dumbbell cutting die.
• Cut the specimen from the sample strip as stated in the test standard for that material.

Steps to prepare rectangular shape specimen

• Cut a Strip of 25 mm width and appropriate length.
• Now mark the specimen strip as follows.
• Marking should be done in such a way that the distance between the grips of the machine is 100 mm after clamping of the specimen.
• This distance can vary from test standard to test standard.
• Mark the specimen at a distance of 25 mm from both ends to ensure proper and equal clamping force on the specimen on both ends.

In this way, you can easily prepare the testing specimen in both shapes for determining its tensile strength. If you need any more help, then you can easily give us a call at +91 9210903903 or email us at info@prestogroup.com. Our team of technical experts will guide you well regarding your queries.
