Flexural Strength Testing is used to determine the flex or bending properties of a material. Sometimes referred to as a transverse beam test, it involves placing a sample between two points or supports and initiating a load using a third point or with two points which are respectively called 3-Point Bend and 4-Point Bend testing.

Many different loading schemes fall under the broad category of shear testing. Most often performed on small coupons of metals, composites and adhesives, these tests apply force or displacement until the specimen fractures. Single lap, double lap, short beam shear and torsion are typical configurations. All of these tests are designed to characterize materials under shear loading by determining shear-stress/shear-strain curves and material properties, including shear strengths and shear moduli.

Forced entry testing is conducted on building envelope and system components such as doors, windows, wall panels and escape hatches as an attempt to penetrate or distort an edge in order to disengage a fitting or device from its mountings and allow access. The US Department of State has developed a standard that all building envelope and system components used in both domestic security and overseas facilities are required to achieve. NTS conducts all forced entry test in their DOS approved facility in accordance to the SD-STD-01.01 standard. All testing is witnessed by DOS personnel with NTS providing reports on all tests performed.

The effects of electromagnetic pulses (EMP) on electronics can be severe, but pose an even more devastating threat to the processes and infrastructures that they support. Designing equipment and systems to withstand the effects of EMPs now will reduce the impacts of potential EMP attacks on our electronics in the future.

Differential scanning calorimetry (DSC) measures Specific Heat Capacity, Heat of Transition, and the Temperature of Phase Changes and Melting Points. DSC measures the rate of heat flow, and compares differences between the heat flow rate of the test sample and known reference materials. As a sample undergoes a transition (melting, crystallization, etc.), heat is absorbed or emitted. This change in heat flow is then measured by the system and can be analyzed. The difference determines variations in material composition, crystallinity and oxidation.

During research and product development of any Internet of Things (IoT) device or Machine to Machine (M2M) product, it is important to make sure the antennas designed or selected will perform the way they are intended. For example, when designing an antenna for a large stationary device like a vending machine, it is likely installed or placed against a wall. Designing or selecting an antenna that concentrates its energy and radiates toward the front of the device would be ideal for this environment. In the case of a mobile device, like a smart phone, it is important for the antenna to radiate in all directions and not lose communication link when the user moves around or faces a particular direction away from the cell tower. Over-the-Air antenna testing and measurements are the only way to qualify the entire signal path and antenna pattern of a wireless device.

The indirect effects of lightning are caused primarily by earth-voltage rises that occur when the flash dumps charge into the earth and by the intense electromagnetic field associated with the flash. These fields and earth-voltage rises have enough energy to cause component damage up to a kilometer or more from the actual strike. Indirect effects are most commonly induced into system interconnecting cables and may damage or upset electronic components.

NTS has been testing wireless home networking devices (typically referenced as “Wi-Fi” devices) almost since their introduction. Since 1999, NTS has been perform testing of wireless LAN products based on the IEEE-802.11 standard (e.g., 802.11a, 802.11b, 802.11g, 802.11n, and even the latest drafts of 802.11ac and 802.11ad). Wi-Fi products are typically designed to allow you to connect your personal computer to a wireless network typically connected to the Internet. Wi-Fi “hot-spots” are available in locations across the country (e.g., coffee shops, hotels, etc.), and have become common-place. However, Wi-Fi is expanding into other areas, including healthcare and smart energy (e.g., connecting your smart device to the internet to track energy usage, etc.).

The market for lithium-ion batteries is expected expand to more than $87 billion by 2027. Lithium batteries have higher energy density and lower discharge rate compared to nickel-metal hydride and lead acid batteries—and costs continue to drop. With more advantages than traditional batteries, a wide range of industries rely on lithium batteries, including automotive (particularly in the electric vehicle sub-sector), aerospace, defense, and medical, telecommunications, industrial, and consumer electronics. To ensure batteries are properly tested and safe to operate in real-world scenarios for the above industries, NTS conducts robust testing.
