A non-profit organization, IEEE is the world's leading professional association for the advancement of technology.
The IEEE name was originally an acronym for the Institute of Electrical and Electronics Engineers, Inc.
Today, the organization's scope of interest has expanded into so many related fields that it is simply referred to by the letters I-E-E-E (pronounced Eye-triple-E).

Use low pressure (altitude) tests to determine if radios can withstand and/or operate in a low pressure environment and/or withstand rapid pressure changes.

Procedure I - Storage/Air Transport.
Procedure I is appropriate if the radio is to be transported or stored at high ground elevations or transported by air in its shipping/storage configuration.

Procedure II - Operation/Air Carriage.
Use Procedure II to determine the performance of the radios under low pressure conditions.

Use high temperature tests to obtain data to help evaluate effects of high temperature conditions on radios safety, integrity, and performance.

Procedure I - Storage.
Use Procedure I to investigate how high temperatures during storage affect the radios (integrity of materials, and safety/performance of the radios).

Procedure II - Operation.
Use Procedure II to investigate how high ambient temperatures may affect radios performance while it is operating.

Use low temperature testing to measure how low temperature conditions during storage, operation, and manipulation affect radios safety, integrity, and performance.

Procedure I - Storage.
Use Procedure I to investigate how low temperatures during storage affect radios safety during and after storage, and performance after storage.

Procedure II - Operation.
Use Procedure II to investigate how well the radios operates in low temperature environments.

Use temperature shock tests to determine if radios can withstand sudden changes in the temperature of the surrounding atmosphere without experiencing physical damage or deterioration in performance.

Procedure I (Steady State)
Procedure I employs constant temperature at each of the extreme shock conditions because, in many instances, the thermal shock itself so outweighs the other thermal effects that the test may be performed using two constant temperatures.

To determine the heating effects of direct solar radiation on radios. And to help identify the actinic (photodegradation) effects of direct solar radiation.

Procedure I – Cycling (heating effects).
Use Procedure I to investigate response temperatures when radios is exposed in the open in realistically hot climates and is expected to perform without degradation during and after exposure.

The purpose of this method is to help determine the effectiveness of protective covers, cases, and seals in preventing the penetration of water into the radios. Also the capability of the radios to satisfy its performance requirements during and after exposure to water.

Procedure I - Rain and Blowing Rain
Procedure I is applicable for radios which will be deployed out doors and which will be unprotected from rain or blowing rain.

Procedure III - Drip.
Procedure III is appropriate when the radio is normally protected from rain but may be exposed to falling water from condensation or leakage from upper surfaces.

The purpose of this method is to determine the resistance of radios to the effects of a warm, humid atmosphere.

Test duration of the minimum number of 48-hour cycles for this test is five. Temperature/humidity levels are 60°C and 95% RH

The salt fog method is performed to determine the effectiveness of protective coatings and finishes on materials.
Use a 5 ± 1% salt solution concentration.

These tests are performed to help evaluate the ability of radios to resist the effects of dust that may obstruct openings, penetrate into cracks, crevices, bearings, and joints and to evaluate the effectiveness of filters.

Procedure I - Blowing Dust.
Use Procedure I to investigate how susceptible radios is to concentrations of blowing dust (< 149 Pm).

The immersion test is performed to determine if radios can withstand immersion or partial immersion in water and operate as required during or following immersion.

Procedure I - Immersion.
Procedure I (Immersion) primarily addresses leakage during immersion of encased radios.
Depth of immersion is 1m.
Duration of immersion is 30-minutes

Develop radios to function in and withstand the vibration exposures of a life cycle including synergistic effects of other environmental factors, radios duty cycle, and maintenance. Although verify that radios will function in and withstand the vibration exposures of a life cycle.

Procedure I - General vibration.
Use Procedure I for those cases where a test item is secured to a vibration exciter and vibration is applied to the test item at the fixture/test item interface. Steady state or transient vibration may be applied as appropriate.

Shock tests are performed to provide a degree of confidence that radios can physically and functionally withstand the relatively infrequent, non-repetitive shocks encountered in handling, transportation, and service environments, and determine the radio's fragility level, in order that packaging may be designed to protect the radio's physical and functional integrity.

Procedure I - Functional Shock.
Procedure I is intended to test radios (including mechanical, electrical, hydraulic, and electronic) in its functional mode and to assess the physical integrity, continuity and functionality of the radios to shock. In general, the radios is required to function during the shock and to survive without damage to shocks representative of those that may be encountered during operational service.

Procedure IV - Transit Drop.
Procedure IV is intended for radios either outside of or within its transit or combination case, or as prepared for field use (carried to a combat situation by man, truck, rail, etc.). This procedure is used to determine if the radios is capable of withstanding the shocks normally induced by loading and unloading when it is outside of its transit or combination case, or inside its transit or combination case. Such shocks are accidental, but may impair the functioning of the radios.
