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.

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.

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.

Dielectric Withstanding Voltage Test
The dielectric withstanding voltage test (also called high-potential, over-potential voltage-breakdown, or dielectric-strength test) consists of the application of a voltage significantly higher than rated voltage for a specific time, between mutually insulated portions of a component part or between insulated portions and ground. This is used to prove that the component part can operate safely at its rated voltage and withstand momentary over-potentials due to switching, surges, and other similar phenomena.

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.

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.

Electrostatic Discharge Test
The electrostatic discharge test is designed to determine the ability of equipment to perform its intended function without permanent degradation of performance as a result of an air discharged electrostatic pulse. Electrostatic discharge is the result of an unbalanced electrical charge. Typically, it is created by insulator surfaces rubbing together or pulling apart. A transfer of electrostatic charge between bodies (materials, components, etc.) at different electrostatic potentials is caused by direct contact.

Particle Impact Noise Detection (PIND) Test
This test detects the presence of free moving particulate contaminants within sealed cavity devices. This test is specifically directed toward relays and other devices where internal mechanism noise makes rejection exclusively by threshold level impractical. This test method also may be used prior to final sealing in the manufacturing sequence as a means of eliminating loose particles from the interior of the device.

Shock Test
Shock testing determines the ability of equipment to withstand the infrequent non-repetitive shocks encountered in handling, transportation, and service and to continue to function, where required. Also, shock tests verify that equipment will not detach from its mounting during these tests.

Accelerated Weathering Test
Accelerated weathering consists of relatively long term exposure of items to specified environments.This test is designed to observe for material degradation.

Random Drop (Non-Packaged) Test
The random drop test is used to determine the effects on non-packaged components of random, repeated dropping due to handling, shipping, and other field service conditions. The test is an accelerated test designed to indicate structural and mechanical weaknesses of types not necessarily detected in shock and vibration tests.

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.
