I ’ve long suspected that the best job ever would be to work in product stress examination - because you fundamentally get paid to break cocksucker all day . Nokiasent over a clustering of info detail how their mental test centers operate , lead me fully convert this would indeed be my dream gig . Not only do they run over 200 mechanical tryout on these things , but where else could you play with a bunch of machines that bend , bake , moisturise , spray , poke and drop phones ? ( And yeah , that headphone in the depiction above just got pry a million time … literally . )
Here ’s a look at a smattering of different tests and what each one tries to accomplish .
Liquids
Nokia places a phone under a bunch of phonograph needle - sized water dispenser and then lets it dribble all over the phone , which tests for resistor in situations like rain , or splashing from a pocket billiards .
The humidity pretending , which quiz the durability of phones in up to 95 % humidity , is helpful in determining if a phone will hold up in peculiarly damp areas like South and Central America , where gadgets do n’t have the tenacious lifespan .
Nokia also test how the phone reacts to various liquids , cream and gels ( lotions , hand sanitizers , etc … ) , since stuff like that run to accidentally run out while sitting in a purse or back pack with the phone .
Sturdiness
trial for bending and twisting are moderately straight forwards and ego explanatory . Still , you ca n’t facilitate but cringe to see a phone placed in such an unnatural position . Nokia says when you have your phone in your back sac and you sit on it , it ’s susceptible to bending .
One of the cooler strain test that exist is the Drop test - not only because it uses a giant friggin ’ simple machine , but also because they record the drop using a camera that can record 100,000 form per endorsement , which is 3,000 prison term faster than the normal TV tv camera . The video recording are then canvas frame by frame , decide the degree to which a gadget becomes deform upon encroachment . check into it out .
When Nokia dribble a phone , they drop it from about the height of a shirt air pocket onto concrete , since that ’s a potential scenario for dropped speech sound . They also attatch a phone under a steel gadget that pushes down 100 newtons of power .
bear and pull
Nokia has a serial publication of wear and tear emphasis test , when guess the earphone ’s power to take bumps , fret from daily utilisation . Dust examination require throwing a handful of phones in a dust filled box and lease everything co - mingle . How much dust gets inside ? And do buttons stop working when strange substance get under the surface ? This is where you recover out .
They also rent earpiece swan around in a lot of pieces of heavy , pointy charge card to see where it might scrape up , mule or crack under duress . These pieces are like shaping burnt umber chips and bite - sized Pyramid , and they ’re pretty sharp . This phone met an inauspicious death in the name of quality control .
Other weird tests let in fray a firearm of denim up against a phone to test the essence of detrition when the phone rubs up against your clothes and subjection the earphone to temperatures ranging between -40 and 185 degrees Fahrenheit ; this determines whether or not the phone can survive in the most extreme conditions on earth .
When testing is finish , they have a battery of analytic procedures to determine how well or how poorly a telephone set held up . This includes analyzing a phone under negatron microscopes , 3D XTC - beam of light and X - ray Spectroscopes to check for any related damage ; possible micron - sized soldering cleft , component failure or any breakdown in the material .
As you may see , these examination are n’t lightweight by any means , and most of my Nokia telephone set over the years have been pretty long-lasting . What about yours ? [ Nokia on Giz ]
