  • Peel Resistance of Adhesive Bonds

    ASTM D1781 - National Technical Systems

    This test method is used to compare adhesion between flexible and rigid adherents, or between flexible facing of a sandwich structure and its core. Comparisons of adhesives and processes are only applicable when test specimens and conditions are the same. The peel resistance may indicate degree of cure for relatively brittle adhesives.

  • Wind and Rain Testing

    National Technical Systems

    Severe wind and rain conditions can be encountered anywhere in the world, often with little notice. Excessive wind can interfere with communications equipment, lead to premature wear and corrosion, and limit radar effectiveness. Properly testing your product or system components against wind and rain is necessary both for regulatory compliance and overall quality control.

  • Fungus Testing Lab

    National Technical Systems

    Many products that operate in warm, humid environments must be tested to withstand fungal attacks, since this problem can cause a myriad of operational challenges. From interfering with delicate system components to causing premature wear and corrosion, a fungal infestation can lead to a number of problems than affect the lifespan of your product and potentially cause serious liability issues.

  • Salt-Fog and Salt Spray Testing

    National Technical Systems

    Salt-fog and salt spray testing is conducted to determine the effectiveness of protective coatings and finishes on materials, as well as the effects of salt deposits on the physical and electrical aspects of a product. NTS can conduct your corrosion testing to meet the requirements of various regulatory standards as well as customized testing programs. We have the chambers, support equipment and the technical expertise to ensure the proper application of testing requirements to your product in a professional laboratory environment.

  • Sand and Dust Testing

    National Technical Systems

    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.

  • Scanning Acoustic Microscopy (CSAM)

    National Technical Systems

    Scanning Acoustic Microscopy, also known as C-SAM or Acoustic Micro Imaging or AMI, outstanding benefit is its ability to find hidden defects within assemblies and materials that can occur during manufacturing or environmental testing. Defects such as delaminations, voids and cracks can be identified and analyzed more effectively using Acoustic Microscopy than with any other inspection method.Unlike other non-destructive techniques such as X-Ray and Infrared Imaging, Acoustic Microscopy is highly sensitive to the elastic properties of the materials it travels through. Because of this, the ability of Acoustic Microscopy to find and characterize these physical defects is clearly superior. Typical applications include production control, failure analysis, and product development.Through the use of ultra-high frequency ultrasound, C-SAM non-destructively finds and characterizes physical defects—such as cracks, voids, delaminations and porosity— that occur during manufacturing, environmental testing or even under normal component operation. Because of the unique aspects of the technology, AMI can locate these defects better than any other inspection method.

  • Dual Shaker Testing

    National Technical Systems

    NTS has a number of facilities capable of conducting dual shaker testing, vibration testing utilizing multiple electrodynamic exciters, for the evaluation of large payloads.Once such example was conducted as part of the test program for NASA’s Lunar Atmosphere and Dust Environment Explorer or LADEE. NTS worked with NASA’s Ames Research Center for simulated environmental testing of the LADEE observatory which included dual shaker vibration.Vibration testing on the observatory was conducted utilizing the NTS Santa Clarita facilities tandem Ling B-340 electrodynamic exciters. These exciters allow either dual shaker vibration testing, or in the case of the LADEE observatory tests, they minimize the test set-up time. The electrodynamic exciters were staged with one in the thrust axis and the other set-up for lateral axes vibration. This dual shaker set up allowed for a quick transition from one test to the other. During the tests, the vibration test lab was maintained at a class 10,000 cleanliness level.

  • Force Limited Vibration Testing

    National Technical Systems

    In vibration testing of high value aerospace hardware, over testing of light, high performance structures is a great concern. Discrepancies between the mechanical impedances and the force capabilities of the mounting structure and the vibration shaker can cause catastrophic structural and functional problems to test item. The effectiveness of the radar depends on it retaining its structural integrity over the entire surface of the antenna and that all its electronics are a) tested at, or near levels they will experience in its service life and b) the resonance of various parts of the radar follow those of the model. Consequently, the vibration test lab required 60 data channels to accurately verify the design of the instrument and its ability to withstand launch, cruise and deployment loads. To avoid over testing, NTS used Force Limiting Test Process using four force transducers to prevent exceeding total load of 1000 pounds.

  • Testing of Hydrophobic and Super-Hydrophobic Coatings

    National Technical Systems

    Coatings provide critical asset protection in some of the harshest operating environments. With advanced coating materials being introduced at an ever greater pace, applied to everything from consumer products to medical and industrial electronics, the need to understand their performance qualities is essential.Hydrophobic and Superhydrophobic coating is a nanoscopic surface layer that repels water. Droplets hitting this kind of coating can fully rebound in the shape of column or pancake. In industry, super-hydrophobic coatings are used in ultra-dry surface applications. The coating causes an almost imperceptibly thin layer of air to form on top of a surface. Super-hydrophobic coatings are also found in nature; they appear on plant leaves, such as the Lotus leaf, and some insect wings. Hydrophobic coatings such as the NeverWet product, can be sprayed onto objects to make them waterproof. The spray is anti-corrosive and anti-icing; has cleaning capabilities; and can be used to protect circuits and grids.

  • Analysis via Fourier Transform Infrared Spectroscopy (FTIR)

    National Technical Systems

    Fourier Transform Infrared Spectroscopy (FTIR) is a standard technique used in the identification of contaminating materials on the surface of printed circuit boards (PCBs) and around the leads of electronic components (BGA, capacitors, resistors, inductors, connectors, diodes, oscillators, transformers, IC, etc.) on printed circuit assemblies (PCAs). Additionally, FTIR can be used for “simpler” identifications, such as determining a specific type of plastic or rubber compound.

  • Temperature & Humidity Testing

    National Technical Systems

    Temperature and humidity testing determines how components, subsystems and complete systems behave in severe environments that involve elevated temperatures and high or fluctuating relative humidity. The tests can be static with constant temperature and humidity, they can involve the cycling of both, they can be temperature-humidity bias tests (where the moisture is used to induce a failure in an electrical device) or some combination of all of these.
