Stability test chambers are specialized enclosures that create a controlled temperature and humidity environment. Various industries such as pharmaceuticals, packaging, environmental testing, and controlled storage utilize reach-in or walk-in chambers for stability tests. The chambers are designed to find defects or weaknesses in products under varying conditions by providing a controlled testing environment. Stability chamber qualification requirements fall under installation, operation, and performance categories. Stability chambers undergo these three qualification tests before being placed in operation. Stability Chamber Qualification Requirements For an environmental chamber to receive a certification to conduct stability tests, it must undergo a three-part qualification process. The

A key element of entrepreneurial success is product quality. This is especially so in today's competitive business landscape. However, product quality goes beyond making products that are desirable to consumers. It can involve a host of other elements such as ensuring products: Are safe for use Meet industry standards Have an ideal shelf life Are packaged appropriately Ensuring products have the desired quality is non-negotiable because any defective product can put consumers at risk. Therefore, stability testing plays a key role in so many industries. Read on to learn more about stability test chambers and their various applications. What are

Batteries play an important role in our lives, in more ways than one. Just as modern technological solutions continue to evolve, batteries need to advance to keep pace. Testing plays an important role in making sure that batteries can perform safely and effectively. Lithium batteries, commonly the power source for electronic gadgets, are also used for more critical uses such as powering electric vehicles and life-saving medical equipment. Lithium battery testing standards are in place to ensure batteries meet performance, reliability, and safety requirements. Types of Lithium Battery Testing Standards While battery safety can appear complex at first, once you

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

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

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

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

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
