How To Perform Tensile Strength Test?

Tensile strength testing machines are popularly used to evaluate the strength or durability of the material. The testing instrument can measure various mechanical properties such as modulus of elasticity, elongation, strength, etc. The tensometer is often used as a part of the production line to check the quality of raw materials used to manufacture final products. It helps manufacturers and designers deliver quality products with zero quality failures. The tensile strength testing machine by Pacorr is equipped with highly advanced features like microprocessor-based software, a controller, a dedicated gearbox, a drive, overload protection, etc.

What Is Tensile Strength?

Tensile strength is one of the most vital factors that help define the strength and durability of end products. Materials with poor elongation get deformed easily, leading to significant loss and damage to the brand's reputation. These products are often rejected as low-quality materials and sold off at much cheaper prices. Tensile strength testing equipment is primarily used to measure the strength of plastic materials under tension. This type of equipment is essential in the plastic industry because it helps manufacturers ensure that their products meet specific strength and quality standards.

How To Perform Tensile Strength Test:

Step 1: To begin the scientific test, set up the equipment based on the manufacturer's instructions. Position the upper and lower clamps in a position feasible to accommodate the test sample. Proper vertical alignment of the claps is crucial to avoid bending or side loading during the test. Most equipment offers both automatic and manual modes. Set various parameters like speed, mode etc. The universal testing machine is available in different sizes and capacities.

Step 2: Attach a piece of the specimen to be tested to the instrument. Choose the proper specimen grip by adjusting the clasp using a screw or adjusting mechanism. Ensure the specimen is well secured for an accurate reading. Ensure the machine's grip and faces are well-adjusted to the sample's dimensions.

Step 3: Start the test on automatic mode. The grips firmly hold the end of the specimen. The instrument gradually stretches the specimen with one end holding the sample steady while the other moves constantly until distortion or break point. This helps the tensometer record the elongation value. Repeat the test using manual mode for accurate results.

The results offer valuable information regarding the sample material. The process can prove beneficial to industrial and laboratory setups. It can help identify any weaknesses in the plastic material that could lead to product failure or safety concerns. Manufacturers can then devise corrective measures to improve the quality of their materials and products, ensuring that they meet the requirements of their customers and regulatory agencies. By using this type of equipment in their production lines, manufacturers can reduce the risk of product failures, increase customer satisfaction, and maintain a competitive edge in the marketplace.

How To Choose The Right Instrument

It is essential to invest in quality instruments for standardised tests that determine the yield strength and ductility of the sample material. The tensile strength tester by Pacorr is designed in compliance with globally acclaimed standards such as ASTM & ISO. The instrument can accurately measure test values and record parameters for comparative analysis. It helps in material selection and performance analysis of various quality raw materials. Floor-standing models are much more user-friendly and convenient to handle and perform tensile tests. An instrument capable of performing both manual and automatic test are ideal for determining precise test values. Data gathering software-enabled instruments help acquire accurate information for test results accepted globally.
