After all the computer modeling, welding tests, durability trials (and of course, steak dinners), inking an auto deal can take years.
Several methods were used, namely measurement of impact velocity, the determination of kinetic energy, splitting performance tests, durability tests of blades and handles, and user trials.
To test durability, they implanted the gel in dogs, whose larynges are similar to those of humans.
Elsewhere in the building's 50 testing labs, white-coated assistants test stereos and TV's in a soundproof chamber, a machine opens and shuts kitchen cabinets thousands of times to test durability, and "sensory panelists" sample potato chips, rating them for texture and flavor.
Of course, there are about 1,000 steps to go before Bursaw even gets there, like designing the glass structure and texture, improving traction, testing durability, manufacturing the panels on a large scale, etc.
The cyclic wheel loading test (durability test) demonstrated that the generator composite sustained 2000 cycles of 400 kg-weighed wheel loading and a prominent output voltage peak produced was as high as 40.45 V.
The specimens were subjected to various tests, namely; compressive strength test, durability (permeability using initial surface absorption test (ISAT) and field emission scanning electron microscopy (FESEM)) for 360 days exposure.
To test durability of the response to medication, primary and secondary outcomes' measurements were repeated 8 weeks after medication period (the 12-week follow-up visit).
The hydrogen permeation test and durability test consisting of three cycles of alternately changing the temperature and transmembrane pressure difference were carried out using a single gas, hydrogen, and it was found that the hydrogen permeation flux remained constant during the durability test and that the helium leakage did not increase after the durability test.
The difficulty of carrying out this extensive evaluation by means of time-consuming tests of durability led to the search for a single-factor or shortened durability test that would give a reliable evaluation.
It is the second most demanding track on the engine — Monza being the first — and it therefore tests engine durability, and also the car's tires.
