One of the cornerstones of NTS’ work in smart grid has been our certification program for the ZigBee Alliance. One of ZigBee’s largest and most popular application profiles is the ZigBee Smart Energy standard. NTS is the largest certifier of all ZigBee products, and has completed certification for over 85% of the Smart Energy products certified by the ZigBee Alliance. We have developed test tools to assist in the pre-certification of new devices for manufacturers, as well as validation of devices for utilities. In addition, NTS also has been selected by USNAP to perform certification testing for smart appliance manufacturers.

Surface Insulation Resistance (SIR), as defined by IPC, is the electrical resistance of an insulating material between a pair of contacts, conductors, or grounding devices that is determined under specified environmental and electrical conditions.In respect to the world of printed circuit boards (PCBs) and printed circuit assemblies (PCAs), SIR testing—also commonly referred to as Temperature Humidity Bias (THB) testing—is used to evaluate a product’s or a process’ ability to resist “failure” by means of current leakage or an electrical short (i.e., dendritic growth). SIR testing is typically performed under elevated temperature and humidity conditions—such as 85°C/85% RH and 40°C/90%—with periodic insulation resistance (IR) measurements obtained.

Fluid power systems play a critical role in many industries, and are one of the three major forms of power transmission along with electrical and mechanical power systems. In many cases, however, mechanical and electrical methods cannot provide a practical power transmission solution. In these cases, fluid power (whether hydraulic or pneumatic) is often used because it can deliver linear and rotary motion with high force and torque within a smaller, lighter package than is possible with other forms of power transmission. Some of the most common applications of hydraulic systems are in heavy construction and off-highway equipment. Other applications can be seen in aircraft, mass transportation systems (such as trains), construction, mining, agriculture, waste reduction, and utility equipment. The various components (such as valves, actuators, cylinders, accumulators, etc.) that make up these systems must perform reliably and have a reasonable life span. Only a thorough test program carried out under simulated field use conditions can insure that any component part or assembly will meet its original design goals for performance, reliability and longevity. Many internationally recognized organizations have published test standards that apply to hydraulic/pneumatic and fluid power systems and components. Some of these organizations are:

Contamination Analysis, which begins with a set of basic evaluations that on most occasions will answer the “What is this?” question. The protocol contains four parts:*Visual Examination*Organic Analytical Testing by Fourier Transform Infrared (FTIR) Spectroscopy*Elemental Analytical Testing by Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM/EDS)*Ionic Analytical Testing by Ion Chromatography (IC)

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.

IPC was founded in 1957 as the Institute for Printed Circuits. Today, it is a global trade association representing the electronics industry with a focus on design, PCB manufacturing and electronics assembly. IPC has over 3700 members, including Aerojet Rocketdyne, Rockwell Collins, Lockheed Martin Mission Systems & Training, and Parker Hannifin Electronic Controls.

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.
