Changes in air pressure and other environmental fluctuations, such as changes in temperature and humidity, can affect the performance of electronics. Thermal vacuum testing simulates atmospheric conditions, including temperature and altitude, at high altitudes and in space. Vacuum testing mimics these environmental changes to help manufacturers evaluate their long-term effects on essential and non-essential components. It’s important to test these environmental changes because air does not conduct electricity in the same way that metal does, so air works well as an electric insulating medium in electronic devices. The insulating properties of air are ideal at sea level, but it begins

Product failure can be catastrophic, especially in circumstances when lives are at stake. Transportation at high altitudes can alter the pressure of sealed products, and this pressure changes significantly with every flight. These pressure changes can damage gaskets, potentially exposing parts to humidity and contaminants that can alter performance. In addition, many electronics depend on the normal insulating properties of standard air pressure to avoid short circuits in components. High altitude conditions remove that air and corresponding electrical insulation thus creating short circuits and critical component failures that otherwise would not be experienced at normal site pressures found near the

Altitude testing demonstrates a product’s ability to survive air transport or show that the product can remain a functional piece of an aircraft’s overall assembly. Components used in aircraft and aerospace equipment must be able to withstand extreme cold temperatures while at altitude, but they must also be able to endure the rapid temperature changes equipment undergoes during takeoff and landing. Altitude testing helps aircraft and aerospace parts manufacturers ensure that their components can compensate for these changes. Benefits of Product Testing in an Altitude Chamber All equipment, particularly flight critical components, must meet high aerospace requirements. Altitude testing ensures

Aircraft and space vehicles, such as satellites and rockets, endure extreme conditions while in flight. These extreme conditions can cause failure in critical components, which can have catastrophic results. Testing parts for aircraft and space vehicles in an altitude chamber can help manufacturers develop durable parts that operate well during flight, despite the quickly-changing and extreme conditions caused by high altitudes. Altitude testing measures a number of factors aircraft and space vehicle components are likely to experience at extreme heights. Environmental Extremes at High Altitudes Life close to the surface of the planet is quite comfortable, with generally survivable temperatures

In Part-1, we went over the importance of conducting environmental tests for electronic products. The reason that you can keep the same hairdryer for five years, the same TV for ten years, and the same car for fifteen years is due to product testing, most of which can be done in a Tenney Environmental Test Chamber. Here in Part-2 we will go over the different types of environmental testing: simulation vs. stimulation. Simulation tests the product in the environment in which it normally operates. In other words, simulation tests how well the electronics perform in normal temperature, humidity, and vibration

In our last blog post, The Importance of Product Testing, we discussed the different ways the automotive industry uses Tenney Environmental test chambers for testing various parts of the vehicles we drive daily. In Part-1 of our two-part blog series, Environmental Testing: Improving the Life Span of Electronics, we will go over the various ways your everyday electronic devices, such as the television, computer, and tablets, are tested. When an electronic product is purchased, the expectation is that it will work well, last a long time, and not catch on fire. New products may have design flaws or new materials

Testing is an essential part of developing a quality product. It helps manufacturers create products that are reliable within certain technical standards. In other words, testing is a necessary step for product development teams to go through to provide high quality products that last. Perhaps most importantly, product testing can ensure that an item is safe for general use. Testing ensures that the products manufacturers bring to market hold up to even the most rugged and ruthless conditions, similar to those consumers may encounter or put their products through. Putting a product through extensive testing helps a manufacturer measure the
