WHAT IS MIL-STD-810G?

So what exactly does MIL-SPEC approved mean to you - the end user? It means that the quality, durability and resilience of our products meets military requirement for mobile military applications. We worked with an established testing agency well versed and experienced in offering a full suite of testing for aerospace, defense, telecommunications, and industrial customers, including environmental, mechanical, NEBS, and EMI/EMC testing.

MIL-STD-810, Environmental Engineering Considerations and Laboratory Tests, is a United States Military Standard that emphasizes tailoring an equipment's environmental design and test limits to the conditions that it will experience throughout its service life, and establishing chamber test methods that replicate the effects of environments on the equipment rather than imitating the environments themselves. The MIL-STD-810 test series are approved for use by all departments and agencies of the United States Department of Defense (DoD). Although prepared specifically for military applications, the standard is often used for commercial products as well. The current document revision (as of 2012) is MIL-STD-810G which was issued on October 31, 2008. It superseded MIL-STD-810F released on January 1, 2000 and which was last updated on May 5, 2003. The standard's guidance and test methods are intended to: (i) Define environmental stress sequences, durations, and levels of equipment life cycles; (ii) Be used to develop analysis and test criteria tailored to the equipment and its environmental life cycle; (iii) Evaluate equipment's performance when exposed to a life cycle of environmental stresses; (iv) Identify deficiencies, shortcomings, and defects in equipment design, materials, manufacturing processes, packaging techniques, and maintenance methods; and (v) Demonstrate compliance with contractual requirements.

MIL-STD-810 is maintained by a Tri-Service partnership that includes the USAF, the US Army, and the US Navy. The USAF, Wright-Patterson Air Force Base, is Preparing Activity and the Army and Navy provide custodianship support. The U.S. Army Test and Evaluation Command, or ATEC, serves as Lead Standardization Activity, and is chartered under the Defense Standardization Program (DSP) with maintaining the functional expertise and serving as the DoD-wide technical focal point for the standard.

GreenPath Technologies contracted an independent testing facility, Environ Laboratories to conduct all MIL-STD 810G testing. Testing was completed in May 2013, with passing results achieved on all tests. A brief summary, test reports and test certificates follow.

MIL-STD-810G TEST DESCRIPTIONS TESTED AND APPROVED:

MILSTD-810G TESTING SUMMARY – GreenPath Technologies requested that Environ Laboratories conduct nine tests to be completed to the latest MIL-STD – 810G standards.

#R47858-1 – TEMPERATURE SHOCK TEST

The STORM Solar Module was subjected to temperature extremes of -20°C and +70°C, with the changes occurring in less than one minute, for three full cycles. Visual inspection found no sign of damage or degradation.

#R47858-2 – HIGH TEMEPERATURE – CYCLIC Hot Dry Induced Conditions Cycle

In this test, the STORM Solar module had to endure temperatures ranging from 35°C to 71°C in an aggressive set of cycles -- 7 24-hour cycles (168 hours). The temperature was increased from 35°C to 71°C over 14 hours, and then decreased from 71°C to 35°C over 10 hours. This cycle was repeated 6 times for a total of 7 cycles. At the completion of testing, the unit was visually inspected, an no evidence of damage or degradation was found.

#R47858-3– HIGH TEMEPERATURE – CONSTANT –Operation, Constant Temperature (Deployed)

This test was designed to subject the STORM Solar Module to high temperatures and test the operation of the module during peak temperatures – in this test, 75°C. Open-circuit voltage was measured before, during and after, using the same light source – the test chamber light, with the following results: Before testing: 5.0vDC; during testing: 4.5vDC; after testing: 5.0 vDC. Visual inspection also showed no evidence of damage or degradation.

#R47858-4– SHOCK –Transit Drop

The STORM Solar Module was dropped from a height of 48” onto a concrete floor on each face, edge, and corner for a total of 26 drops. Upon completion, visual inspection showed no evidence of damage or degradation.

#R47858-5 – SALT FOG

In this test, the STORM Solar Module had to endure temperatures of 35°C (95°F), while a 5% salt solution was atomized into the chamber. The unit was then exposed to two complete 48-hour cycles – 24 hours exposed to salt fog, and 24 hours of drying time. The visal examination showed that corrosion was not visible anywhere on the module.

#R47858-6 – IMMERSION

To ensure that the STORM Solar Module could withstand all sorts of weather conditions and situations, the next test we requested required full submersion at a depth of one meter for 30 minutes. The unit was sealed in a pressurized test chamber to simulate the one meter depth

VISUAL RESULTS: No evidence of damage or degradation

#R47858-7– HUMIDITY -- Aggravated Cycle

The STORM Solar Module in this test was subjected to ten 24-hour cycles at 95% humidity, at 60°C for 8hours, then adjusted to 30°C over 8 hours, and finally at 30°C for 8 hours. At the end of the 240 hours, the unit was inspected, and no evidence of damage or degradation was found. The unit also opened and closed properly after the exposure.

#R47858-8 – VIBRATION –Common Carrier, Vertical Axis Profile

The test performed here required that the module endure extreme vibration on the X-, Y-, and Z-axis. Visual inspection afterward revealed no evidence of damage or degradation and the test unit remained intact.

#R47858-9 – FUNGUS

Out of all the tests commissioned by GreenPath Technologies, the Fungus test was the longest to conduct. Te module and test control strips were inoculated with a mixed-spore suspension, and then sealed in the test chamber set at to 30°C and 95% relative humidity. After 7 days, the chamber was opened to verify sufficient fungl growth. After verification, the chamber was then sealed to continue the incubation period of 28 days. The test unit was then removed from the chamber and immediately examined under magnification. Visual inspection confirmed LIGHT fungal growth on the cloth casing: a MIL-STD-810G Rating of 2, which is passing results.

**ALL TEST UNITS WERE SUBJECTED TO OPEN-CIRCUIT VOLTAGE CHECKS PRIOR TO SUBMISSION TO ENVIRON LABORATORIES. AS A COURTESY, ENVIRON ALSO CONDUCTED OPEN-CIRCUIT VOLTAGE CHECKS AFTER TESTS WERE COMPLETE, AND GPT VERIFIED UPON THE RETURN OF TEST UNITS**
