Environmental Simulation Testing
National Technical Systems (NTS)
What is environmental simulation testing? Simply put, simulated test environments are all about preparing products for real-world use. This is accomplished by gaining as much testing experience and performance data as early as possible during the products’ lifecycles. Simulated environmental testing usually involves creating artificial environments for test items to determine their expected resilience to their anticipated environments.

Bird Strike Testing
Many people may consider flocking birds such as sea gulls, ravens, and pigeons to be a nuisance but otherwise harmless. However, to jet aircraft and individuals carried aboard, the possibility of a bird strike poses an existential threat. For instance, when U.S. Airways Flight 1549 crashed into the Hudson River in New York back in January, 2009, the subsequent investigations performed by the NTSB and FAA found that a double bird strike during take-off (one in each engine) caused the incident.

Corrosion Testing
Realistically, the only way to know whether or not a particular product will withstand corrosive environments is to test it in corrosive environments. Unfortunately, testing equipment in their intended environments would take years at the rates that corrosion normally occurs. This means the solution involves testing equipment under conditions that produce highly accelerated rates of corrosion. Our corrosion testing laboratories are equipped to provide corrosion testing and corrosion monitoring under accelerated conditions to simulate years’ worth of accumulated corrosion within a period of days.

Explosive Atmosphere Testing
Will your product operate in a highly volatile environment without creating ignition and causing an explosion? Explosive atmosphere testing provides vital information about motors, lighting systems, bilge pumps, aircraft components, electronics, and other systems. Explosive atmosphere testing determines whether a product will be able to operate properly in a fuel contaminated, highly volatile environment without creating ignition and causing an explosion. Causes of ignition vary from tiny electrical arcs in battery-operated equipment to hot spots on surfaces of sealed, encased units, to sparks from other mechanical sources.

Fire and Flammability Testing
Will your products, subsystems or components operate as designed when exposed to fire conditions, or will they go up in flames? Fire and flammability testing is required for products used in a wide range of industries, including Aerospace, Defense, Telecommunications, and Consumer Electronics. NTS offers fire and flammability testing services, typically falling into two categories: 1) ignition and flame spread, and 2) fire resistance.

Hail Impact Testing
Hail is an extremely destructive force of nature, especially for aircraft, with impacts occurring at more than 600 mph. NTS performs hail and stone strike testing and high velocity hail strike testing. These tests can be performed using clear ice, stone and aluminum projectiles of up to two inches in diameter, fired at velocities of up to 741 miles per hour(331.4m/sec, 1087.4 f/sec). Typical test programs include aircraft windshields, antennas, radomes, and wheel/brake assemblies. Using a laser equipped system with a high degree of accuracy, repeatable impacts can be performed to within a quarter inch of the desired target. This accuracy allows NTS to test even the smallest of test samples, as well as limit the potential damage area of larger units.

Highly Accelerated Thermal Shock (HATS2™) Testing
NTS is the exclusive provider of HATS2™testing services in North America. Thermal shock testing has long been the accepted method to check robustness and reliability of plated-through holes and solder joint connections. Historically, thermal shock testing has been performed utilizing either dual chamber air-to-air systems or liquid-to-liquid systems. Both of these methods offer significant disadvantages in cost, time, and the fact that the samples must be transported between the hot and cold environments. Transportation of the samples between the temperature environments makes monitoring the resistance of the samples difficult and inaccurate due to the length and quantity of wires. The infrequent monitoring typically associated with traditional thermal shock methods also makes detection of “glitch” conditions marginal at best.

Humidity Testing
Whenever products and materials spend extended periods of time in a humid environment, various types of breakdowns can be expected. Coatings can fail. Electronic and optical equipment tends to degrade. Fuels break down. The list of associated failures is extensive.

product
Icing and Freezing Rain Testing
For any product or system component that is regularly exposed to the elements, due diligence and quality control must include testing for all conditions likely to be encountered during use. Freezing rain and ice in particular present a number of obvious challenges for aircraft, automobiles and other vehicles. Rigorous freezing rain tests should be made part of any environmental testing program, both for meeting RTCA DO-160 and other requirements, and for delivering an overall safer and more versatile product to market. As an important partner to the aviation and defense industries, NTS can help you meet these goals.

Immersion Testing
Immersion testing evaluates how well your product or component will hold up when submerged in water or other liquids. This is not limited strictly to waterproofing — other factors, such as the ability to withstand rapid changes in pressure or exposure to caustic chemicals, can also be made a part of testing. As a result, immersion testing is an investment in more robust and durable design. By taking the time to test these factors early in the development process, you can create an all-around better product and shorten your time to market.

product
Ingress Protection Testing
Ingress Protection testing, or IP testing, tests a product’s ability to protect against “ingress,” that is, the infiltration of water, dust and foreign objects. Some of the standards related to IP testing are MIL-STD-810 (Military), RTCA/DO-160 (Radio Technical Commission for Aeronautics), and IEC 60529 (International Electrotechnical Commission).

Sand and Dust Testing
NTS operates some of the largest and most accurate sand and dust testing chambers available in the industry. We can accommodate parts in excess of 8 ft3 (0.25 m3) and comply with the requirements of various regulatory standards. While sand or dust circulate at up to 40 mph (65 kph) we can modify the test according to your special requirements, including running at temperatures of up to +200°F (+95°C). A calibrated “hopper” which assures that an adequate amount of contaminant is entering into circulation manages the input to the chambers. In addition to measured inputs, NTS employs an electronic beam, which determines that there is the right mixture of sand or dust and air in the test medium at any given time. This enables our technicians to adjust for loss in real time, and make corrections to ensure that the test article is exposed to the harmful particulate matter for the requisite amount of time.
