Test items and instructions:
Shell material:
Shell testing includes the following steps:
1, to see what kind of materials used by the tested products,such as aluminum alloy, engineering plastics, etc. , toinvestigate the appearance, texture and heat dissipationeffect;
2. Press the finger on the back of the screen to observe whetherthe water ripple will appear, and investigate the firmness ofthe shell;
3, one hand picked up a corner of the tablet computer,investigate its shell anti slip ability;
4, sharp metal scratch the back of the fuselage, observe whetherit is easy to leave scratches, investigate the durability ofthe shell.
According to the results of the test, Zhongguancun onlineevaluation room will be given: excellent, good, to be improved,poor, five grades of assessment results.
Screen effects:
Screen testing is divided into two parts: dark environment andstrong light environment:
1, full screen in a dark environment shows two fixedhigh-definition pictures, respectively, from the front, about45 degrees, 45 degrees (the camera to take pictures and settingsare to be fixed) , by comparing the positive effect on thedisplay screen resolution and color reproduction, visual angleof display screen contrast side to study the;
2, play a fixed high-definition video, with the same DV forpositive recording, to investigate dynamic picture fluency(whether there is a drag) and sound effects. Finally, the abovetests are repeated under a fixed strong light source, and thebrightness and reflection of the screen are investigated.According to the results of the test, Zhongguancun onlineevaluation room will be given: excellent, excellent, good, tobe improved, poor, five grades of assessment results.Network connection:

Dragging and testing a program icon on the top left corner ofthe screen interface of the computer screen, placing theprogram icon in the lower right corner of the screen accordingto the diagonal direction of the screen. There is no pause inthe drag process, can smoothly complete the whole process, thatthe touch sensitivity performance of "good", if the drag iconout of control can not be completed, "said touch sensitivityto be improved".
Endurance capacity:
Test with common video formats supported by tablet computers.After the source copy to the tablet computer, adjust the screenbrightness to medium, connect the headset to adjust the volumeto moderate, close to the tested product "automatic standbyfunction, loop test video, to be almost exhausted when thebattery system will shut down or sleep, recorded at the momentof time to assess endurance performance.
According to the test results, more than 12 hours for"excellent", 8 hours - 12 hours for "excellent", 4 hours - 8hours for "good", 2 hours - 4 hours for "to be improved", "2hours" is "bad"".
Starting speed:
The definition of the starting time is the time consumedby thenormal use of the main interface from the moment when the powerswitch is switched off to the main interface of the operatingsystem when the power is completely cut off. Record the time
and evaluate it.
According to the test results, 0 seconds to 10 seconds is"excellent", 11 seconds-20 seconds is "excellent", 21 seconds- 30 seconds is "good", more than 30 seconds is "to beimproved"".
Storage capacity:
The storage capacity of tablet computers is defined as thestorage capacity of the fuselage with no external storagedevices.
500GB above is "excellent", 250GB to 500GB is "excellent", 80GBto 250GB is "good", "80GB" is "to be improved"".
Fuselage noise:
In the case of 25 dB ambient noise, the noise meter is testedat a distance of 30cm away from the fuselage of the flat panelcomputer and the noise decibel is obtained.
Accordingto the testresults, 25dBto30dB is "excellent", 31dBto 35dB is "excellent", 36dB to 40dB is "good", 40dB to 50dBis "to be improved", 50dB is above "bad".
Fuselage cooling:
Test with common video formats supported by tablet computers.After the source copy to the tablet computer, the screen tomedium brightness, the continuous playback of video after one
hour, the use of FLUKE Ti25 thermal imager to observe thesurface temperature at the bottom of the product, and thec amera.
According to the test results, the temperature below 37 degrees,coverage rate of 100% is excellent, 80%-100% is excellent,60%-80% is good, 40%-60% is to be improved, and 40% is below".Software applications:
Web browser, chat software, reading software, audio and videoplayback tools, image processing software, navigation function,Flash, Alipay, game software, handwriting recognition software,spreadsheet tools, meet the above eleven applications for"excellent", the six meet the "good", six for"to be improved".Stability:
The stability of the product was tested by using a thermostat,and the test was divided into high temperature and lowt emperature
1. Low temperature stability test. Set the thermostattemperature below fifteen degrees below zero and keep it forfifteen minutes until it reaches the temperature;
2. High temperature stability test. Set the instrumenttemperature to 35 degrees above zero and keep it for fifteenminutes after reaching the temperature.
If the product to be tested in the two test are not an unstable
state, "excellent", such as a test of unstable state is to beimproved, such as the two test showed unstable state is poor".(Note: Generally speaking, the unstable state refers to thecrash, the running speed is significantly reduced or damagedand other abnormal effects of normal use)
Portabi lity:
According to the measured product screen size/body size, bodythickness and body weight are evaluated, Zhongguancun onlineevaluation roomwill be given: good, good, needs to be improved,poor grades, five grades.
