Terminal Mechanical Strength Test
-
The terminal strength test is used to performed to determine whether the design of electrical terminals and their method of attachment can withstand mechanical stresses to which they will be subjected during installation or disassembly in equipment. These stresses must be withstood by the component without sustaining damage which would affect either the integrity of the terminals or the operation of the component part itself. Procedures are established in this method for testing, for example wire-lead terminals, flexible-flat-strip or tab-lead terminals, and rigid-type terminals which are threaded or have other arrangements for attaching conductors. The forces applied during the test consist of direct axial, radial or tension pulls, twist, bending torsion, and the torque exerted by the application of nuts or screws on threaded terminals.

Highly Accelerated Stress Screening (HASS) Test
-
HASS consists of high and low temperature and 3 axis vibration testing performed either individually or in combination.Highly accelerated stress screening is a technique for identifying process flaws in equipment during production. HASS subjects equipment to overstress conditions but at a level which does not affect design life.For assistance in designing a HASS test program contact the laboratory.

Radiographic Inspection Test
-
The radiographic inspection is a non-destructive x-ray method for detecting internal physical defects in small component parts which are not otherwise visible. Radiographic techniques are intended to reveal such flaws as improper positioning of elements, voids in encapsulating or potting compounds, inhomogeneities in materials, presence of foreign materials, broken elements, etc.

Electrical Contacts Test
-
The electrical contact testing is performed to determine the reliability of equipment under various contacting conditions. A few types of electrical contact tests are: contact-chatter monitoring, contact resistance, intermediate, and low level contact switching.

Product
Corrosion Test
-
The purpose of this test is to determine the resistance of materials and protective coatings to corrosive atmospheres when a more corrosive environment than the salt fog/spray test is required. The test is used when material is stored or operated in areas, for example, where acidic atmospheres exist, such as in industrial areas or near the exhausts of any fuel-burning device. Gases such as sulfur dioxide are used to replicate the exhausts of fuel burning devices.

Fluid Contamination Test
-
Fluid contamination testing determines the abilities of materials to withstand the contaminating fluids, to which they are exposed in service.

Product
Electrical Measurements Test
-
The tests are performed to measure and collect data from electrical and electronic parts using various measurement methods including, but not limited, to the following: capacitance, resistance, winding resistance, insulation resistance, magnetic permeability, power input, and quality factor Q.

Pressure Test
-
The pressure tests demonstrate if a test item can operate to its standard while undergoing extreme rapid pressure changes. Two of the pressure tests are: altitude (low pressure), and explosive decompression.

Product
Temperature Test
-
The temperature tests are performed to determine if objects can operate normally under various temperature conditions, such as high and low temperature, temperature cycling, and temperature shock.

Solar Radiation (Sunshine) Test
-
This test determines the effects of direct solar radiation on components and material. The heating effects of solar radiation differ from those of high air temperature in that the amount of heat absorbed depends on the roughness and color of the surface on which the radiation is incident and the angle of incidence to the sun. Variations in the intensity of solar radiation over the surface of the component, may cause components to expand or contract at different rates, which can lead to severe stresses and loss of structural integrity. In addition, degradation due to photo-chemical changes can occur such as fading of color, deterioration of natural and synthetic elastomers and polymers. The test items that are subjected to solar radiation testing are those that are exposed to solar radiation during its life cycle, in the open, in warm climates.

Strain Gauge Test
-
This test measures the structural stresses induced in equipment when subjected to various environmental and operational loads. Strain gages, which are resistive devices whose outputs are proportional to the amount that they are deformed under strain, are placed at selected locations to yield stress levels which may then be compared to design allowable limits.

Product
Acceleration Testing
-
The acceleration test is performed on a centrifuge to assure that material can structurally withstand the steady state inertia loads that are induced by platform acceleration, deceleration, and maneuver in the service environment, and can function without degradation during and following exposure to these forces. Acceleration tests are also used to assure that material does not become hazardous after exposure to crash loads. The acceleration test method is applicable to material that is installed in mobile platforms such as aircraft, helicopters, aerospace vehicles, air-carried stores, ground-launched missiles, trains, ships, automotive vehicles, etc.

Electromagnetic Interference Test
-
Electromagnetic interference (also known as radio frequency interference) tests are used to determine the electromagnetic characteristics of electrical, electronic, and electro-mechanical equipment. Electromagnetic interference, both radiated or conducted, can affect the performance of equipment. Electromagnetic interference tests are specified as follows: conducted emission, radiated emission, conducted susceptibility, and radiated susceptibility.

Explosive Atmosphere Test
-
This test demonstrates that a part will not ignite while operating in an explosive ambient atmosphere. The tests are conducted at ground level pressure as well as reduced barometric pressures, in a closed explosion-proof chamber.
