A Review of Lithium Battery Basics

Posted: Oct 07, 2021
Your life today is powered by lithium batteries. Your mobile phone and laptop computer are operational because of them. Electric cars and transport already use them, and as they gain more popularity, we will rely on lithium batteries to power more transportation options in the future. The ability to have portable power on demand is a foundation of the modern world but lithium batteries are not new, with the chemistry first being discovered in 1912. So, let's have a closer look at the basics of lithium batteries and how they work. Why Lithium Batteries Are Used Lithium batteries are more

Steady State Stability Testing of Pharmaceutical Products

Posted: Jan 28, 2021
The pharmaceutical industry requires stability storage and testing for their products. This ensures that their product will maintain an acceptable level of quality during the product life cycle. This testing documents how stable a product is and provides evidence of variation of efficiency and integrity of the product over time. It considers the effect of different physical, chemical, and microbiological factors. This type of pharmaceutical testing is done by placing samples of a drug in a steady-state stability test chamber that simulates different temperatures and humidity conditions. Different samples are removed from those conditions at different times to observe the

Environmental Testing in the Automotive Market

Posted: Jan 16, 2020
Today’s cars and trucks are tough, but the extreme temperatures, humidity, and use environments can be tougher. The environment can push automotive components to their failure, which puts drivers and passengers at risk. Environmental testing is used in the automotive industry to ensure that vehicles can weather the storm of conditions they may encounter. Environmental test chambers simulate various conditions and stressors that automotive components will likely endure some time in their lifetime. Testing helps manufacturers determine if they need to make any changes to the design or composition of an automotive component which in turn decreases warranty costs associated

Out of This World: A Look at Tenney's History with the Space Industry

Posted: Oct 01, 2019
This month celebrates the history of the space industry with the annual World Space Week, which runs from October 4th to the 10th. As the largest space event on Earth, World Space Week celebrates the contributions space science and technology have made “to the betterment of the human condition.” Tenney is proud of its long history with the space industry and we are excited to see what the future brings. The Early Years of Space Exploration The theme for 2019 is “The Moon: Gateway to the Stars.” This year marks the 50th anniversary of Apollo 11 and the first human

Vacuum Testing to Prevent Product Failure – Part 2

Posted: Sep 14, 2018
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

Vacuum Testing to Prevent Product Failure – Part 1

Posted: Aug 01, 2018
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

The Importance of Altitude Testing for Aircraft and Space Vehicles: Part 2

Posted: Jul 13, 2018
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

The Importance of Altitude Testing for Aircraft and Space Vehicles: Part 1

Posted: Jun 15, 2018
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
