G-SHOCK toughness the quality of the certification test...!

1 is a test to prove the "toughness" of the G-SHOCK ...

Speaking of G-SHOCK "toughness". but that the high reliability, is supported from a number of professionals who are active in harsh environments, so you would not even introduce again. However, the user is not necessarily used in harsh environments all. G-SHOCK to say it's tough, but should have some people develop a sense of simple question "specifically how much Is it tough?" He said.

In this study, let's report can be called upon to achieve the trust of high G-SHOCK, the field of quality assurance test. Since post as much video was captured while I have an authorized special from Casio is also possible, and there be a look!

With toughness mechanism the latest "TRIPLE G RESIST" Sky cockpit series "GW-A1000" (left). Various G-SHOCK, which marks its 30th anniversary in 2013, the 30th anniversary model will appeared! (right)

Severity that I do not think test for Clock

Casio watch Division Quality Assurance Department Mr. Koyama Mutsumi

Was visited, Casio Computer Technology Center Hamra familiar. Of us to guide, it's Koyama Mutsu Mr. Clock Division Quality Assurance Department.

Koyama , "several tests that you see now is what to do to prototype prior to mass production products. throughout the study of these, to see if there is a problem with the design, or to the operation of the provisions street"

- Any such sampling test of the products in the mass production, do you do the same test?

Koyama products that are "mass-produced, and tested in the factory. There is also a test carried out in the extraction and I and some of the 100% tested. course, is carried out in the total number, the test that a wound does not or attached to the exterior of the product I only "

Drop impact test

Was guided first "drop impact test." The test apparatus form height measuring instrument for use in body measurements, such as increased. There is a system of two groups on the floor, while in the new barter more majestic, ambient is surrounded by a fence just there.

Koyama said , "Both, is a machine for testing the impact of the fall. however, are intended to accelerate fall. When it is free fall, one without the fence the person you are surrounded by free fall, with a fence the height of the machine If I'm not able to reproduce only strength has been dropped from. lowering from a high place more is required, and voila.'m required a mechanism such as throw, you can use it this. would with the spring in the arm top portion I'm down with a strong force "

- Well, I'm creating a situation where you have to throw as using the spring, fall from high places is G-SHOCK.

Koyama said it "is. the drop test, I had been dropped by hand before, to drop where you want to drop it'm difficult. So, I did you to drop by controlling the posture in the Machine"

Drop test machine. The top of the cylinder, a spring for throw down a strong force G-SHOCK is attached	GXW-56 that was set to drop tester.Clock has been released by the left and right arm open at the same time as the injection, to fall

Koyama presses the button to set the machine G-SHOCK the (GXW-56), arm which set the clock continue to rise, stop at the top. Moment the alert resounded with Pipipipipi Tsu!, Hurled on the floor of the concrete at a frightening pace GXW-56 is ....

I gasped involuntarily. But, GXW-56 that was lying on the floor has been around calmly. Scratch like wounds does not stick. Indeed, it's GXW-56, which has a two-layer urethane bezel and inner protector αGEL of (α gel) entered.

Koyama you ever scratch the "exterior. But are you looking at in this study, is out. displayed or has messed clock part is whether running firmly, parts When you have or have gone off I. At that point, you will want to review the design and assembly process "

Next: rock beat!

2 swing! beat!

Hammer impact test

I have you to show a "hammer impact test" after. To use, it's equipment, such as laboratory instruments to change by selling the earlier, to be used in teaching physics at all. The hammer mounted, when you release your hands raised to a vertical position 5kg! What this hammer was swung is, but to hit the G-SHOCK of the pedestal.

Koyama "drop test also test the impact, but it also. can give an impact to the point of" here ", surely with a hammer, damage whereas come out prominently in the exterior part in the drop test , this place will be given damage inside the watch it, so take off the band when the hammer.: the impact gets scattered in the band (Ed. Note is in a state of only watch body), as drop test at the time I do not even "

Hammer impact test equipment. The tip of the hammer so heavy From the look of it, GW-5600, which was laid on the pedestal can be seen

Koyama said, set the base standard model of the G-SHOCK "GW-5600" while saying so. Lift the hammer, and remove your hand. Hammer that is swung down with locus of arc. GW-5600 to be blown off with a hard sound of Gatsu~tsu!. The scene was reminded how the golf ball that is tee up was punched at a furious driver shot. But, it is working as if nothing per GW-5600.

Koyama said , "Make the clock face, side, and back, for all aspects of this study. the back of the G-SHOCK is a metal lid, a fine metal sound I will if it is exposed to here."

- It is bad for the heart as well, not my watch. The test is I guess not do in Basel limited model of MR-G indeed.

Koyama said "I'll do of course (laughs)"

-? Although the prototype because eh example, that is, strength, and is also required such expensive parts and we'll also use the artificial ruby ​​and lacquered ....

Koyama and ask for strength to such "expensive parts, you'll help the expensive parts in other parts of, I make the either be considered. whether or not it contains an expensive no matter how part, claiming the G-SHOCK or more, you must clear the criteria for that. therefore, is done in the same way test "

Vibration test

Vibration tester size, such as commercial refrigerators

Vibration test is performed by using a vibration generator, large generating such speed and magnitude of the amplitude, various vibrations.Since it is assumed that the vibration resistance of G-SHOCK is, to wear even when you use the vibration of the running of the track, and jackhammer and rolling 圧機 of road construction.

They might get broken in one shot if a mechanical watch, it's extremely harsh environment. Test time varies depending on the model, but in the test for a long time, make sure that there are cases where intermittently, is performed about a week in total while changing the direction.

For anti-vibration model, auto parts vibration test method in (JIS D1601 4 species A), in reference to (vibration acceleration of up to 20G) grade required for two-wheeled vehicles in-vehicle equipment, etc., to confirm the anti-vibration performance.

The three put the water pressure! turn!

Centrifuge test

Essential in quality check of G-SHOCK · Sky cockpit series, a centrifuge test. In this case, the steady-state acceleration test in standard (ISO 2669), we have been under test (centrifugal gravity of up to 15G) highest grade required for aircraft equipment.

Centrifuge testing machine, such as a turntable record

At the center of the device, such as a turntable Records G-SHOCK "GW-4000" is fixed to a portion of the Casio Digital Camera "EXILIM" borderless. If you put the switch to lower the windshield of equipment, turntable began to rotate vigorously.

At the same time, centrifugal gravity associated with horizontal rotation's take the GW-4000. In addition, EXILIM because the shot in movie the movement of the needle at this time, to see whether it is working properly by looking at this.

Koyama rotate one around the needle in the "test. might consider cases needle or got stuck in the dial, needle and deviate in the case of a defective individual. You withstand this test" TRIPLE It is, indeed if any design of G RESIST ". The clock will generally not stand first"

"Of course EXILIM" video recording camera that is attached to the centrifuge testing machine, (left). Focus firmly in manual focus (right). Start the experiment from the time you turned on the movie recording button

- GW-4000 is in any case, should not there is the fact, will break EXILIM for photography is no longer withstand the centrifugal force?

Koyama "EXILIM are what high-speed rotation, but because it is the center of rotation, had to do not have to worry about most of centrifugal force"

Get it. By the way, because I can have you also provides video this time, this EXILIM have taken actually, I would like to have a look.

Waterproof test

To reproduce 10 atm and 20 atm, it is necessary to secure the depth 100m, 200m of the normally, but it is difficult in practice. Therefore, the test is carried out using an apparatus that can be pressurized with water.

Immerse G-SHOCK to a device that water was stretched, and put a switch, all-enclosing the clock lid of semi-cylindrical metal appeared in the water. I pressurize the inside of the lid, but the pressure applied to different (water pressure resistance performance) for each specification of the model.

Where the waterproof test equipment, you have set the water pressure applied to the clock

Submerge in water clock to be tested (left). Thereafter, a metal cover covers the clock inside is pressurized. GW-5600 that is removed from the water after the test. No evidence of inundation! (Right)

4 I shoot in the electron gun of over 10,000 volts!

Static test

Static electricity is a natural enemy of electronics. However, Immunity electrical performance also called into question the G-SHOCK. In fact, troubled or broken by static electricity instantaneous that occur, for example, when you come in contact with the door of the car, or when I took off the sweater, period of time is more messed up.

Static test equipment. Use the static gun on the desk, to discharge to watch

The power section of the static testing machine. I set interval and discharge voltage, and frequency

Koyama is "test, we have a measure of quality given continuously international standard of 8,000 volts, the voltage more. It has been said that static electricity when you take off the sweater and made ​​tens of thousands of volts thousands. It may spark looks and snap, static electricity occurs in the dark, but it would be beyond the 10,000 volts at such time.

However, in an instant, static electricity in the day-to-day life is short only happen a few times.But, you give it continuously continuously in the test. You willl "continuously" This, I'm a pretty hard conditions for electronic equipment "

Static electricity gun that is connected to the power supply cable in the (?), Mr. Koyama to go pat the surface of the GW-5600. Each time the clock and the gun is in contact with, sound unpleasant and Bachibachibachi ... is. And closer to the metal button, a small pale lightning's run. When I except the GW-5600 while I think no, this is, indeed be dangerous in electronics, is moving firmly still. There is no evidence button and exterior like burnt!

Button endurance test

Test button durability, turn the device to press the button on the clock in pin earnestly. Set the number of times to be pushed default number of times (several million times), each button is starting test. The end of the study press and hold the button on the clock pin of the device repeatedly, and do a default number of times.Button is pressed or firmly, or there is no change in the push feeling, I want to ensure that each function is working properly after the test.

Device button endurance test. Pin diagonal square moves in order, I press the button on the clock

5 is irradiated with intense light artificial sun!

Shaker mixer test

Test to put the G-SHOCK in a stainless steel bottle, shake to continue earnestly for half a day. Shock itself is not very large, but that's continue to be shaken a long time, that it is with quite severe for precision machinery. Even after you have continued to receive a shock for a long time, to check module would work properly.

Shaker mixer, to the random motion is not constant

Artificial solar irradiation test

Tests of irradiating light from a strong light source that mimics the sun. By changing the angle of the platform which laid the clock and continue to irradiate light from various angles. We are closer to the light source the clock in stages and yet, I will increase the amount of light. By the way, illumination of the artificial sun is pretty intense, as I was recommended to wear sunglasses during the tour.

Koyama "In this study, to examine whether the module is a not malfunction by intense light. Generally, electricity I'm flows through an optical semiconductor electronic components and tiny. you from such as between parts rarely, Is there to be a bad light from entering the module inside the watch. Casio watches operate on the power-saving, especially the minute, external impact it is large "

Artificial solar irradiation test equipment. Light is irradiated from the circular opening of the upper box

While increasing the amount gradually, and irradiated with artificial sunlight.To check if there is no place to change the irradiation position by changing the angle of the pedestal clock is installed, malfunction occurs

6 pull!

strength tensile test

Strength test of the band. Make sure that you do not come off or cut to beyond - "provision weight test method in (JIS B 7001) (MAX200N) clock" the pull while applying power slowly band on the clock of the set,.

Koyama, who set the "GXW-56" in the strength tensile testing machine

Spool the upper and lower, go pull gradually urethane band	View tensile weight hanging on urethane band. Currently, about 210N (21kg)

It should be noted that the performance of the factory only, performance decreases due to aging this. However, a variety of factors and humidity condition, such as ultraviolet rays of maintenance are intertwined in performance degradation, that simulated a difficult so extremely.

This time, it was realized that witnessing one after another severe test, backed sturdy and of the G-SHOCK, to test a number of once again "toughness to be able to rely on". By knowing the background of the development and manufacturing, further, G-SHOCK which continues ticking time in silence at the wrist of us will come regrettable think love also.
