Impact Test Apparatus In Low Temperature Test Chamber

The impact test apparatus should be used in conjunction with the low-temperature box, and the fixture should be placed on a sponge rubber pad with a thickness of about 40mm. It should be placed in a suitable low-temperature box before and during the test. Drop impact height: adjustable from 10 to 250mm. The impact test apparatus is suitable for impact tests on plugs, sockets, switches, screw glands, covers, wires and cables, and electrical conduits. After the test, wipe off the water droplets on the surface and place it in a ventilated and dry place.

When it comes to testing materials and parts in extreme temperatures, an impact test apparatus in a low temperature test chamber is one of the best tools available. Understanding the different types of impact tests and choosing the right apparatus can help you get accurate results, protect your materials from damage, and maximize efficiency. The impact test apparatus in low temperature test chamber is used to assess the impact resistance of electrical accessories at low temperatures, and is also used to assess the low-temperature impact resistance of wires and cables. The device comply the test standards such as : IEC 60811-1-4, GB2099.1-2021、GB 2951.4, VDE 0620, IEC 60884-1 :2013, IEC 540, VDE 0472.

Whether you’re testing the impact resistance of a material or the reliability of an electronic device, having the right impact test apparatus in a low temperature chamber is essential. In this guide, we’ll explain how to prepare and use your apparatus correctly in a low-temperature test chamber, as well as provide tips for safety and efficiency. To ensure accurate testing results in the low temperature test chamber, it is important to secure the specimens in a stable and secure position. Make sure to use appropriate holders and fixers that are suitable for the chamber temperature conditions.

What is an Impact Test Apparatus? An impact test apparatus is a device used to measure the amount of force required to break or deform a material. The apparatus can be used for both destructive and non-destructive testing, making it an essential tool in the manufacturing industry. It helps ensure that materials meet certain quality and performance requirements before being used in production. Additionally, impact tests are often conducted on flexible cords and cables to make sure they are safe and stable.

Low temperature impact test apparatus is a valuable tool used to test the durability of materials and components in extreme cold temperatures. Testing with low temperature impact test apparatus allows manufacturers to simulate the environment where their products and parts will be used. This improved quality control helps them ensure their products are safe, reliable, and durable in cold weather or extreme temperature environments. The ability of a product or part to withstand these extreme temperatures can make the difference between success and failure for companies looking to enter new markets|Real Photo of Wewon’s Impact Test Apparatus

● Consider Which Impact Testing are Required for Your Sample Type When choosing an impact test apparatus for low temperature tests, consider the tests that are required. Different samples of materials require different types of testing and specification criteria in order to accurately assess their performance in extreme temperatures. For example, single-element tension or compression strength tests can be used to test materials such as metals and plastics while cyclic fatigue or fracture toughness tests are better suited to composites. Understanding which tests are necessary can help you select an appropriate apparatus.

● Establish a Temperature Range and Heating Ramping Methodology Once you have established the tests needed, establish a temperature range that needs to be tested and the process of heating or cooling the specimen accordingly. It is important to choose the right impact test apparatus for low temperature tests as some may not be able to accurately measure at extreme temperatures such as -60°C. Consider also aspects such as specimen creep and thermal degradation; some tests may require additional measures such as heat ramping and thermal cycling. Table 1: For fixed-laid cable samples, the weight of the drop weight used for the test should be specified as follows:

OD (Outer Diameter) mm Drop Weight
4.0 100
4.0 6.0 200
6.0 9.0 300
9.0 12.5 400
12.5 20.0 500
20.0 30.0 750
30.0 50.0 1000
50.0 75.0 1250
75.0 1500

● Consider the Weight, Size and Impact Durability of the Test Samples It is important to consider the weight, size and incremental impact durability of the test samples when selecting an impact test apparatus for low temperatures tests. If samples are too large or heavy, they will not be able to fit in the testing chamber nor run on the machinery. Additionally, if the material to be impact tested has a low tolerance for temperature fluctuation below that of ambient levels then it may be better off tested using another method such as high-temperature mechanical fatigue instead.

● Investigate the Available Impact Test Apparatus and Their Features Careful research and critical evaluation of the test apparatuses available on the market is essential before selecting one for your low temperature tests. Consider the features of each apparatus, such as its maximum temperature, chamber specifications and control systems, along with the setup convenience. When performing impact tests using liquid nitrogen, it is best to select a machine that has an insulated chamber and double racks that can rise securely above zero degree Celsius temperatures. Table 2: For samples of flexible cables, flexible wires and communication cables, the weight of the falling weight used for the test is specified in the table below:

OD (Outer Diameter) mm Drop Weight
For Flat Cord 100
6.0 100
6.0 10.0 200
10.0 15.0 300
15.0 25.0 400
25.0 35.0 500
35.0 600

Low temperature impact test apparatus is beneficial in enhancing the durability of components and materials. The testing results not only help identify any potential weak spots in components and materials, but they also help manufacturers to develop better ways to engineer their products to resist heat or cold temperatures. Knowing the real-world behavior of different materials can also result in significant cost savings due to designing more durable components.

Low temperature impact testing can lead to cost savings in areas which experience extreme temperatures by reducing losses due to production errors and predicting possible failure points. For example, industrial equipment operating in the Arctic region may require a different level of durability than equipment operating in the hot deserts. Benefits of low temperature impact tests include saving time, money and resources involved in re-engineering parts or components that may have otherwise failed during operation.

Low temperature impact tests provide an accurate assessment of how a material or component performs under cold temperatures, allowing engineers to design and build more reliable products and materials. These tests are useful for ensuring that materials, systems, and components operate correctly in severe climates without having to conduct a full-scale field test. By understanding the impact of different temperatures on materials and components, engineers can gain greater confidence in their designs and increase safety performance.
