Any product or system component that’s exposed to the air has the potential to incur damage due to atmospheric conditions and contaminants. For telecommunications, aerospace, automotive and other equipment, these conditions can lead to premature wear and potential liability issues down the line. As a result, air testing equipment has become an important part of the quality-control process.

Advanced Composite Materials (ACMs) have broad, proven applications, in the aircraft, aerospace, and sports equipment sectors. Even more specifically ACMs are very attractive for aircraft and aerospace structural parts. ACMs have been developing for NASA’s Advanced Space Transportation Program, armor protection for Army aviation and the Federal Aviation Administration of the U.S.A., and high-temperature shafting for the Comanche helicopter. Additionally, ACMs have decades of history in military and government aerospace industries. However, much of the new technology is now being developed for secondary or commercial markets, and the technology of advanced composites manufacture is continually evolving.

Highly Accelerated Life Testing (HALT), Highly Accelerated Stress Screening (HASS), and Accelerated Weathering are three methods utilized for early determination of potential problems your products may encounter during the course of their lifetime. These methods are conceptually similar to fatigue testing, as they attempt to wear out test materials or products at highly accelerated rates.

NTS can perform detailed compatibility and functionality testing of your product with various hardware (e.g., platforms, adapters, other Bluetooth peripherals, etc.) and software (e.g., operating systems and other applications). We can also perform interference testing to see how other technologies (e.g., ZigBee, microwaves, cordless phones, etc.) may interfere with your product. We can also perform range testing in our facility to evaluate how well it performs in the real-world.

The intent of arc resistance testing is to distinguish between solid electrical insulating materials. It examines the specimen’s ability to resist an arc with high voltage and low current exposed to the material’s insulating surface. The ASTM arc resistance test for dry and uncontaminated materials centers on the time elapsed until tracking paths form.

Accelerated weathering is the simulation of the damaging effects of long term exposure of coatings, materials, and products to outdoor conditions. There are a number of different types of outdoor conditions accelerated weathering addresses, including wind, rain, icing, sand and dust, and of course, UV exposure.

The American Society for Testing and Materials was founded over a century ago to answer the call for more uniform quality manufacturing standards in the railroad industry. ASTM International is a global organization centered on the development and delivery of international standards. As indicated on its website, ASTM has published nearly 12,000 test methods and standards. Known for advanced technical quality and market relevance, ASTM standards are used in research and development, product testing, and quality systems. ASTM standards are critical elements of the information infrastructure that guides manufacturing and trade in the global economy.

The use of Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM/EDS) in the analysis of failure related issues of printed circuit boards (PCBs), assemblies (PCAs), and electronic components (BGA, capacitors, resistors, inductors, connectors, diodes, oscillators, transformers, IC, etc.) is a well-established and accepted protocol. As opposed to or simply in addition to normal optical microscopy, SEM/EDS allows for the “inspection” of areas of interest in a much more informative way.

Dielectric Constant is used to determine the ability of an insulator to store electrical energy. The dielectric constant is the ratio of the capacitance induced by two metallic plates with an insulator between them to the capacitance of the same plates with air or a vacuum between them. Dissipation factor is defined as the reciprocal of the ratio between the insulating materials capacitive reactance to its resistance at a specified frequency. It measures the inefficiency of an insulating material. If a material were to be used for strictly insulating purposes, it would be better to have a lower dielectric constant.

Comparative tracking index (CTI) is used to assess the relative resistance of insulating materials to tracking. The CTI expressed as that voltage which causes tracking after 50 drops of 0.1 percent ammonium chloride solution have fallen on the material. The results of testing the nominal 3 mm thickness are considered representative of the material’s performance in any thickness.

During installation, transport or repair, many products have a risk of being dropped. While handlers receive training to treat these items with care, mishaps happen to even the most experienced professionals. Drop testing ensures the product stays in its original condition from manufacturing to implementation.In addition to ensuring that products survive their journey from point A to point B, many products are at risk for being dropped or jarred throughout their lifetime. These products include handheld devices and tools, lab equipment, personal computers, field measuring equipment, construction tools, etc. In such cases, drop testing may be required to ensure that expensive tools or equipment are capable of surviving the perils of expected use and abuse.

Conformal coating is applied to electronic circuits to provide a protective barrier to moisture and contamination and to provide electrical insulation. The most common specifications used for conformal coating testing are IPC-CC-830B, Amendment 1: Qualification and Performance of Electrical Insulating Compound for Printed Wiring Assemblies and MIL-I-46058.
