Around the world, solar and other renewable energy technologies are seeing widespread adoption in both residential and commercial applications. As prices drop, and governments continue to offer tax rebates and other incentives for switching from fossil fuels, the market for solar devices will continue to grow. With this growth, there will be an increased need for photovoltaic testing services to confirm new products meet consumer demands for safety and performance. A growing market is also likely to mean increased regulatory demands — something that will require sophisticated partnerships and industry expertise to keep up with.

To evaluate the lethality effectiveness of advanced warheads, one must accurately characterize a warhead’s fragment mass and velocity distributions, along with the blast over-pressure spatial distribution.The lethality effectiveness evaluation of advanced warheads requires accurate characterization of the warhead’s fragment mass and velocity distributions, along with the blast over-pressure spatial distribution.

From sub-atomic particles all the way up to skyscrapers, internal movements and motions resulting from the absorption of energy make all objects vibrate to some degree. This fact means that in a world filled with energy and movement, vibrations — or the oscillating responses of objects when moved from a position of rest — are the norm.

There are generally two types of bending tests. Three-point bend and 4-point bend. The materials that are tested using the flex test method vary from metal, plastic, wood, laminates, particle board, dry wall, ceramic tile, to glass. Bending tests vary greatly based on the product being tested.

Solder joint reliability is defined as the ability of your product’s solder joints to function under given conditions and for a specified period of time without exceeding acceptable failure levels.Whether you are trying to implement a new solder type or new component types, solder joint reliability testing is essential in providing confidence that your product will perform within its intended operating limits. The results from different test programs can be compared to provide an understanding of design requirements for adequate reliability. This provides you with useful technical information for future designs, saving you time and money.

NTS can assist you in determining the usability of your product by providing end-user analysis with various user experience (e.g., novice, intermediate, expert, etc.). NTS coined the phrase “Look and Feel” from the term, “User-Centered Design” or (UCD) by Wesley E. Woodson. Woodson defined UCD, “As the practice of designing products so that the user can perform required use, operation, service and supportive tasks with minimum stress and maximum efficiency.” UCD is an in-depth process of analysis of usability both qualitatively and quantitatively that requires a large amount of time and money. And in today’s competitive market, most developers can’t afford this approach.

Tin whiskers pose a serious problem for electronics of all types. When used as a finish material for electronic components, pure tin can spontaneously grow conductive whiskers. These structures can form electrical paths, affecting the operation of the subject device. The scientific community has yet to agree on the reason for tin whisker growth. Some theories suggest that tin whiskers might occur due to a mechanism of stress relief, especially “compressive” stress, within the tin plating.

Prolonged exposure to solar radiation can be very damaging to equipment that is stored or used outdoors. NTS operates state-of-the-art solar radiation testing facilities, capable of testing to solar standards for various different product types. We utilize proprietary sources of radiation to provide the spectral content and irradiance to the exacting requirements specified by these standards. We also provide the exact temperatures and wind speeds required by these standards.

Transportation simulation testing involves the application or simulation of environments found in the transport of goods and equipment. These environments may include vibration, drop or shock, temperature, loose cargo or bounce, as well as other dynamic or climatic environments. Products and equipment are usually tested in the “shipping” configuration which means they would be packed in the default shipping container or transit case during the test. However, some items may also be tested in an unpacked state if there is an expectation that they might frequently be transported in that manner. Tests are performed not only to test the effects of transport on the product itself, but also to test the adequacy of shipping container design and the interaction between product and container during shipping. There are a number of possible modes of transport for any given item subject to shipping.

NTS is one of only a few facilities in the world capable of performing simulation testing that mimics the extreme conditions found in the upper atmosphere and outer space. By precisely controlling temperature, altitude and humidity, we give you a clearer picture of how your product will respond, allowing you to make engineering changes that reduce your liability and simplify your path to regulatory compliance.

UL’s testing services are organized into sections that evaluate specific types of products. To establish recognition, manufacturers are requested to submit samples for assessment in accordance with specific UL standards. NTS performs the applicable evaluation and testing of these samples and then assembles the data packet for UL review. Upon compliant results, UL then evaluates the test data and makes the final determination as to whether a product is eligible for recognition. Upon test data review and acceptance by UL, Notification of Authorization (NofA) is issued to the manufacturer to apply the UL certification mark to their products.

The ability to withstand sudden changes in temperature is a key attribute for products and components that are subject to harsh environmental conditions or used in other rugged applications. NTS offers several protocols for testing components against the effects of thermal shock, helping you deliver a more reliable end product and maintain compliance with MIL-STD-810 and other standards.

One of the most common mechanical testing methods, tensile testing, is used to determine the behavior of a sample while an axial stretching load is applied. These types of tests may be performed under ambient or controlled (heating or cooling) conditions to determine the tensile properties of a material.
