Analog vs Digital Charpy Impact Tester: Which Fits?

22 Dec 2025

When you are testing the breaking point of heavy-duty steel or high-stress polymers, accuracy is the only thing that matters. The Charpy test remains the undisputed standard for measuring energy absorption, but it forces a tough decision for QA managers: the analog vs. digital charpy impact tester debate.

Instrumented vs Non Instrumented Impact Testing Guide

20 Dec 2025

Nobody can afford a critical component snapping in half when the pressure is on.

Getting a firm grip on exactly how a sample reacts when you hit it with a sudden shock is a non-negotiable requirement in this industry. Breaking things to determine toughness and brittleness is the standard procedure, but here is the reality: not every test delivers the full picture. If you are trying to select the right hardware for your facility, the primary debate always lands on one comparison: Instrumented vs non-instrumented impact testing.

Charpy Impact Testing: Procedure & Standards

19 Dec 2025

Material toughness is a critical property, especially in industries like automotive, aerospace, construction, and infrastructure. When materials are subjected to sudden forces, such as impacts or collisions, their ability to absorb energy without fracturing becomes important.

The Charpy impact test is one of the most reliable and cost-effective methods to measure the toughness of materials. But what exactly is this test, and why is it important for ensuring material durability?

Packaging Drop Test Standards: ASTM vs. ISTA Guide

6 Dec 2025

There is a specific, hollow feeling that comes from shipping out a perfectly manufactured product only to have it arrive at the client's facility looking like it was kicked off the back of a moving truck.

Validating your shipping containers isn't just an optional quality check; it is the primary defense standing between your bottom line and a logistical disaster. But finding the right solution often means confronting two imposing acronyms: ASTM and ISTA.

What is the Drop Test? How It Ensures Product Safety

5 Dec 2025

When products are shipped, stored, and handled, they often encounter unexpected shocks and drops. A drop test measures the durability of both the product and its packaging under such conditions, ensuring they can survive potential impacts during distribution.

In this article, we'll cover the fundamentals of drop testing, how it works, and why it’s important for manufacturers. Whether you’re shipping electronics, medical devices, or everyday items, understanding drop testing can save costs, reduce returns, and ensure happy customers.

Application of Charpy Impact Test and Its Calculation Example

10 Sep 2025

Industries like automotive and construction require a powerful test that helps determine a material's toughness. Not only its ability to bend, but also to absorb energy when there's an impact without breaking. That's why the Charpy test is still commonly practiced today. However, the thing we need to highlight here is the application of Charpy impact test.

Charpy Impact Test vs Drop Weight Test: Key Differences in Impact Testing Methods

25 Jul 2025

Since there are many types of sudden shock loads, a range of impact tests is required across industries. Charpy impact test vs drop weight test is one of the main topics often encountered in discussions related to impact testing.

Aside from their different methods, these two tests also provide different types of measurements. They are designed for distinct assessments and are typically used in industries with different testing requirements. Let us explore both of the impact tests further here.

Cryostat for Impact Testing: Why Precision Cooling Matters in Material Evaluation

28 Mar 2025

If you're preparing specimens for Charpy impact testing, a cryostat gives you the control you need to do it right. It ensures each sample reaches the target low temperature and stays there, helping you avoid the inconsistencies that can arise from manual or uncontrolled cooling methods.

By using a cryostat, you improve your lab's efficiency while maintaining full compliance with testing protocols. It streamlines specimen preparation, reduces test turnaround time, and helps you produce results you can trust, every time.

Impact Tester for Plastic: Reducing Failures with Precision Testing

18 Nov 2024

Plastics are part of our daily lives, from car parts to smartphones, food containers, and toys. But how do manufacturers make sure that these products won’t crack, shatter, or fail under stress? That’s where an impact tester for plastic becomes invaluable.

This instrument helps companies test the durability and resilience of plastic materials, reducing the chances of failure and improving product quality. Here, we’ll explore how precision impact testing can cut down on failures, save costs, and give you confidence that your products are built to last.

What is a Tup Holder in Impact Testing and Why Is It Important?

12 Nov 2024

In impact testing, even the smallest components can have a big impact on accuracy. The tup holder, a seemingly simple fixture, is important for keeping the tup (the striker that hits the material sample) secure and steady. Imagine if each strike varied slightly, test results would lose reliability. With the tup holder in place, each impact remains consistent and precise, revealing a material's true strength and resilience.
