Rugged Android Tablet Testing Method

Rugged Android Tablet Testing Method

A month ago’s article saw what makes a tough Android tablet or cell phone unique in relation to a standard Android tablet or cell phone by featuring the most famous norms and rating frameworks.

IP Ratings (International Protection Rating), NEMA (National Electrical Manufacturer’s Association), and MIL-STD-810G (Military Standard) were totally covered, and this month, we will take a gander at a portion of the testing strategies engaged with these guidelines. These appraisals are for all electrical gadgets, yet the article will be centered around Android cell phones and tablets.

The following are 8 of the testing strategies that tablets and cell phones must suffer to arrive at specific rough guidelines.

High Temperature

There are 3 strategies engaged with testing high temperature: stockpiling, activity, and strategic reserve to operational:

a) Storage methodology uncovered the tablet or cell phone to high temperatures while the Android gadget is killed. It tests the strength of the actual materials that make up the gadget.

b) Operation methodology centers around how the tablet or cell phone endures heat while being used.

c) Tactical-reserve to operational testing checks how the Android gadget functions under various temperatures while working subsequent to being presented to high stockpiling temperatures.

Low Temperature

Low-temperature tests additionally have 3 testing strategies: Storage, operational, and control:

a) Storage – this is equivalent to the capacity methodology above besides with low temperatures.

b) Operational testing includes gradually cooling the Android gadget to the least temperature in the fitting reach and leaving it there for 2 hours, checking outwardly if the Android gadget is as yet working during that time.

c) Manipulation tests the simplicity at which the Android gadget can be set up and dismantled while wearing weighty winter garments (the utilization of gloves may be an obstruction to working the frameworks).

All in all, organizations will distribute both capacity and working temperature particulars, yet infrequently, if at any point, control for cell phones or tablets.


The consequences of this test help to figure out what IP (Ingress Protection) rating the Android gadget gets for security against fluid. There are 2 applicable methodology: Rain and blowing precipitation, and trickles.

a) Rain and blowing precipitation methodology is for Android gadgets that will be utilized outside. The cell phone or tablet is dependent upon the breeze sending water drops at the gadget, with the water 10 degrees Celsius colder than the gadget, for 30 minutes.

b) Drips are focused on Android gadgets that would not be liable to rain, however could in any case be presented to some falling water. Again the water is 10 degrees Celsius underneath the gadget temperature and the water is dropped over the tablet or cell phones upper surface from 1 meter for 15 minutes.


Here, we have 2 methods (stockpiling and travel, and bothered) that test how well the cell phone or tablet can hold up to warm, muggy air:

a) Storage and travel tests the Android gadget in three 24-hour cycles, copying conditions that may happen during capacity and travel, and another three to speak to common habitat cycles.

b) Aggravated uncovered the Android gadget to more outrageous dampness levels for less time. A few analyzers pick this technique as it is less tedious regardless of whether the outcomes don’t totally reflect genuine conditions.

Sand and Dust

Sand and residue test includes 2 strategies (blowing residue and blowing sand) for testing how well the tablet or cell phone can keep out particles:

a) Blowing dust methodology tests entrance (the activity of going in or entering) of residue particles that are more modest than 150 micrometers (μm). To test this methodology, start with the breeze at 8.9 meters/sec (1750 feet/min). At that point, feed the residue at a normal grouping of 10.6 grains per cubic meter (0.3 grains per cubic foot). Keep up for at any rate six hours at a standard encompassing temperature (room temperature with the gadget fueled on), turning the gadget to at last uncover all sides. At that point, raise to working temperature (actually fueled on), bring down the breeze speed, stop the residue, and test for an additional 6 hours, pivoting the gadget as essential.

b) Blowing sand system tests entrance with particles that are between 150 μm and 850 μm. The test begins at an operational temperature and requires a lot higher breeze – 18 to 29 meters/sec (40-65 mph) to move the heavier particles. The sand focus will shift generally relying upon the objective climate — the top of the line reenacts being close to airplane, for instance. The test is run for an hour and a half for each face the cell phone or tablet has, halting the sand and the breeze in the middle of the sides with the goal that it very well may be pivoted securely.
