NATO norms guarantee a superior quality because they have been tested as follows.

The different tests are summarised below. The detailed procedures are available upon special request.

THERMAL SHOCK TEST 107 METHOD A

The thermal shock test is performed to determine the resistance of a part to exposures at extremes of high and low temperatures, and to the shocks of alternate exposures to these extremes, such as would be experienced when equipment or parts are transferred to and from heated shelters in artic areas.  The products are exposed to a flow of air at different temperatures for at least 5 cycles.

HUMIDITY TEST 103 METHOD B

This test is performed to evaluate the properties of materials used in components as they are influenced by the absorption and diffusion of moisture and moisture vapour.  This accelerated environmental test is accomplished by the continuous exposure of the specimen to high relative humidity at an elevated temperature during 96 hours.

SALT SPRAY TEST 101 METHOD A

The purpose of this test is to define if the product is resistant to salt spray.  This accelerated laboratory corrosion test simulates the effects of seacoast atmospheres on metals.  The coating of the product is subjected to a fine mist of salt solution during 96 hours.

SHOCK TEST 213 B METHOD H

The shock test (Sawtooth pulse during 6Ms) is conducted for the purpose of determining the suitability of component parts and subassemblies of electrical and electronic components when subjected to shocks such as those which may be expected as a result of rough handling, transportation and military operations.  The design of the shock machine is not specified, but shock pulse waveforms are specified with tolerances.

VIBRATION TEST 201 A

The vibration test is used to determine the effects on component parts of vibration within the predominant frequency ranges and magnitudes that may be encountered during the field service. The specimen is mounted on a special apparatus and subjected to a simple harmonic motion.

THERMAL STRENGTH TEST 211 METHOD A

This test is performed to determine whether the design of the product and his method of attachment can withstand one or more of the applicable mechanical stresses to which they will be subjected during installation or disassembly in equipment.  This pull of tension test is gradually applied and then maintained for a period of 5 to 10 seconds.
