Assess the impact resistance of the plastics with Izod and Charpy Impact Tester

Materials made up of plastic or metals are essential in several industries. They are versatile and lightweight. It is necessary to determine the impact of forces on plastic to check its durability or life span. To do so, Izod and Charpy testers have been introduced. It is used to perform Izod and Charpy tests on plastic materials.

The izod impact test is very useful since it checks whether the material can withstand the forces during transportation, packaging, and delivery. This tester is mainly used in industries such as automotive, construction, and manufacturing where the products face sudden impact and high chances of damage are there.

Relevance of performing izod and Charpy test

This test is used to assess the durability of plastic materials. Generally, materials made up of plastic get damaged when is sudden shock or impact is applied on them. Izod and Charpy impact testers are used to conduct the test and check whether the materials can take the sudden force without cracks or breakage.

Moreover, this test can determine the impact resistance ability of different materials. By doing so, manufacturers can assess the type of materials that have to be used for specific applications. In simple terms, the notched specimen is placed in the equipment and subjected to a high-speed pendulum hammer and measure the amount of force required to break the specimen. Presto is an established lab equipment manufacturer. Izod impact tester is one of those lab equipment manufactured by Presto. Presto sells high-quality izod and charpy impact tester which helps manufacturers gain insights into the toughness of their materials.

Why the Izod and Charpy Test?

Presto impact tester abide by ASTM D – 256 – 10 standards. The instrument comes with a wiring diagram, instruction manual and calibration certificate as well. The calibration certificates of Presto are from NABL-approved labs. This instrument is essential in quality control departments and metal and plastic testing laboratories where plastic or metal materials are checked against sudden impact or force and calculates the force required to break that material.

Izod and Charpy impact testers calculate the impact strength in terms of J/m. This lab equipment is available with energies from 2.71 to 25.02 Joules and is used to perform Izod tests against plastic materials. The pendulum is controlled by a microprocessor that controls all the functions in accordance with international standards. Regular maintenance of the izod and charpy impact tester will increase its life and chances of damage to the equipment will be minimized.

The factors that impact the durability of the plastic materials

There are various elements that impact the durability of plastic materials. Thus, it is essential to conduct the Izod impact test to assess the impact resistance of plastic materials. Let us go through the parameters that affect the durability of plastic materials.

• Structure and Composition

The sturdiness of plastic materials completely depends on the materials used in forming them. Various types of plastic materials have diverse chemical compositions and molecular structures and it completely depends on whether the type of chemical used to form the plastic can withstand the impact resistance or not. For example, thermoplastics exhibit great sturdiness due to their elongated polymer chains. They possess great strength and durability and can withstand impact resistance for a longer time than other types of plastics.

• Environmental Factors

Environmental factors such as UV ray exposure, extreme temperatures, and moisture can impact the durability of the plastics. Such external environmental factors can definitely impact the strength of the plastic and weaken or degrade it with time. Hence, it is essential to check their impact resistance against variable forces to deliver the right products to the customers.

• Processing Conditions

The impact of processing conditions on plastic materials cannot be neglected. The processing conditions such as high temperature, cooling rates and pressure can affect the materials for sure. These conditions should not be controlled inadequately to avoid any kind of damage to the final product.

Izod and Charpy Test to Gain Customer Satisfaction

When the plastic materials are tested against the sudden force or impact, they might get a break. It shows this kind of plastic is not suitable and will impact customer satisfaction as well. Thus, to achieve customer satisfaction, it is essential to deliver the right products to them by checking their durability.

When plastic materials are checked for their impact resistance and results are recorded, then the right material will be delivered to the customers that will not get damaged during transportation or delivery. It will help in gaining customers and enhance the customer base for the company. It will lead to an increase in revenues and customers will make repetitive purchases from that manufacturer only.

Difference between Izod and Charpy Impact Test

This test is performed to check the strength of plastic materials.  Though both the tests follow the same principle the steps are different to perform them.

The points that differentiate both tests are.

• Position of the Specimen

The first difference between the Izod and Charpy tests is the placement of the specimen in both tests. The specimen is placed vertically in the Izod test and horizontally in the Charpy test.

• Direction of Notch

The direction of the notch is different in both the Izod and Charpy impact tests. It faces the striker in the izod test and it is away from the striker in the Charpy test.

• Notches Types

There are two types of notches for specimens for both tests. For the Izod test, the specimen has a V-notch and for the Charpy test, the specimen has a U-Notch.

• Striking Point

The striking position of the hammer is different for both tests. In the vertical or Izod test, the hammer makes a strike on the upper tip of the specimen. In the Charpy test, the hammer makes a strike at the notch but it would be in the opposite direction.

• Type of hammers

In both the tests, different types of the hammers are used. In the Izod test, the farming hammer is used and in the Charpy test, the Ball Pin hammer is used.

Conclusion

Evaluating the impact resistance of the plastic materials can be done with the help of an izod and Charpy impact tester. This test will ensure that quality products are delivered to the customers. You can gain sufficient information about this lab equipment here.
