What is impact test?
The impact test is used to analyze the resistance of a material. The test involves looking at the material when it experiences a shock that causes the sample to fracture, deform, or break.
Types of impact test
The three most frequent types of tests are:
- Charpy V-notch
- Izad test
- The traction impact test
The three tests determine the same characteristics and differ in the orientation of the test sample.
Purpose of impact test
the purpose is to determine the material’s ability to absorb impact energy. This energy determines the tenacity, the resistance and its characteristics.
Why impact testing is important?
The impact simulation tests are very important to check the resistance of the goods to these possible impacts that might occur during the distribution process.
To carry out these simulation tests, the load is subjected to different tests, such as dropping the goods from a certain height, placing the load on a cart and making it collide or leaving it fixed and crash into a mobile part.
Safe Load Testing Technologies develop two machines that perform impact tests: inclined impact tester and horizontal impact tester(link). Both simulate the horizontal shocks that affects stability and safety of the load, produced by various means of handling and transportation. Although the testing procedure is different, the purpose of both machines is to predict the damages that goods may suffer during the transport and thus avoid losses and reduce costs.
An impact simulation must meet with these regulations
> ASTM D880: Standard Test Method for Impact Testing for Shipping Containers and Systems.
> ASTM D4003: Standard Test Methods for Programmable Horizontal Impact Test for Shipping Containers and Systems.
> ISO 2244: Complete, filled transport packages and unit loads — Horizontal impact tests
> ASTM D5277 Standard Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester.
Benefits of performing an impact test:
> Reduce waste during the distribution process
> Reduce the economic cost
> More rigorous analysis about the risks that may suffer the goods or its packaging
