How Are Rugged Tablet PCs Tested for Ruggedness?

The rugged tablet industry over time has adopted testing standards developed by the Society of Automotive Engineers (SAE), the U.S. military (MIL-STD 810G), the International Electrotechnical Commission (IEC), and other organizations. These testing standards include test methods and certain performance guidelines that must be met in order for a tablet computer to legimately be considered “rugged” by typical industry expectations. These industry standards are extensive and include many requirements, the most often used being: high and low storage and operating temperatures, specifications on the tablet's ability to withstand numerous vibration and humidity conditions, as well as the ability for a tablet to endure rigorous tumble and drop tests. And if that’s not enough, various rain and powerful jetting water tests are employed to verify sealing integrity.

The engineering department at MobileDemand uses creative and brutal methods for testing the durability of their products. They have developed proprietary testing equipment that subjects their tablets to conditions which mimic real world scenarios, and require their products to perform reliably under more adverse conditions and to a higher standard than those required by the current MIL-STD 810G and SAE guidelines.

For example, MIL-STD 810G standards for drop testing requires items to survive a total of 26 drops: once on each face, edge and corner. According to the standard, the 26 drops can be divided among up to five samples of the same test item and the item is not required to be operating. In other words, the product being tested can fail the drop test up to five times and be replaced with another, undamaged unit to complete the test cycle. MobileDemand rugged Windows tablets always have been tested to survive the 26 cycle drop test with only one unit. In addition, MobileDemand tablets are drop tested in operating mode.

The engineers at MobileDemand have gone to great lengths to push the limits in testing their tablets because they know that in the real world, mobile computing devices are often subjected to unusual conditions that cannot be re-created in an artificial environment. Engineers have strapped their tablet to the top of an SUV and driven it through car washes repeatedly, they have rolled them down the side of hilltops and even used them to hammer nails. They have been tumbled over a 1000 times in an IEC compliant 1 meter height tumble test chamber and a commercial clothes dryer. They have endured the severe vibration of an industrial paint shaker.

Recently, the touch panel and LCD industry has been centralizing on an impact test dropping a 228 gram steel ball, 1 1/2 “ diameter onto screens from increasing heights to test screen impact resistance. MobileDemand has added another test station to its torture chamber to facilitate this impact testing on its complete tablets.

At MobileDemand we make sure with our unique tests the tablets can take a licking so in your business they keep on ticking.
