What is a three-proof phone?
The definition of the three-proof mobile phone is very simple. It is a mobile phone with slight dustproof, shockproof and waterproof functions. It is mainly for young users who love outdoor sports or professional users with special needs. With its professional waterproof, dustproof and excellent anti-drop and anti-rolling performance, it can be used in unusually harsh weather conditions and special occasions.
Three anti-mobile phone standard
Based on the national three-defense technical standards, combined with the actual needs of the market and customers, the three defense levels are defined as three levels, namely primary, intermediate and advanced (professional). The three levels are defined as follows:
Primary three-proof standard: IP56 - 5 dust-proof grade, 6-level waterproof grade, 1.5M drop, regular vibration.
Intermediate three-proof standard: IP57 - 5 dust-proof grade, 7-level waterproof grade, 3M drop, regular vibration.
Advanced (professional) three-proof standard: IP68 - 6 dust-proof grade, 8 waterproof grade, 5M drop, regular vibration.
At present, the outdoor three-proof mobile phone standard comes down to the following:
1. IP-XX waterproof and dustproof sealing standard--General waterproof and dustproof sealing standard for outdoor electronic products;
2, RPS (Rugged Phone Standard) - SONIM internal testing standards;
3, AGM OEPT (Outdoor Environment Performance Test) - Based on the IP--XX sealing standard, the drop, crush, vibration test standard, Raytheon-China internal standard;
4, MIL-STD-810F environmental engineering considerations and laboratory tests - the US military defense test method standards.
In addition, almost all brands have three anti-mobile phones, the main outdoor adventure, the professional three anti-mobile phone will not be bad when playing, but for battery life, there is no function, because the field can not be charged at any time, generally two or three thousand .
Three anti-mobile phone test standards
IPX 1
Method Name: Vertical Drip Test
Test equipment: drip test device;
Placement of the sample: Place it on the rotating sample stage at 1r/min according to the normal working position of the sample, and the distance from the top of the sample to the drip port is not more than 200mm;
Test conditions: the amount of dripping is 10.5 mm / min;
Duration: 10min;
IPX 2
Method Name: Tilt 15° Drip Test
Test equipment: drip test device;
Placement of the sample: Make one side of the sample at an angle of 15° to the vertical, and the distance from the top of the sample to the drip is not more than 200 mm. After each test, change the other side for a total of four times;
Test conditions: The amount of dripping is 30.5 mm/min;
Duration: 4 × 2.5 min (10 min total);
IPX 3
Method Name: Water Spray Test
experiment method:
A, swing tube type water spray test;
Test equipment: swing tube type water splashing test device;
Sample placement: Select the swing tube of the appropriate radius so that the height of the sample table is at the diameter of the swing tube, and place the sample on the sample table so that the distance from the top to the sample spout is not more than 200 mm, and the sample stage does not rotate;
Test conditions: The water flow rate is calculated according to the number of water spray holes of the swing tube, 0.07 L/min per hole. When water is sprayed, the water spray holes in the arc are sprayed to the sample at 60 ° on both sides of the swing tube. The test sample was placed in the center of the semicircle of the pendulum tube. The pendulum tube is swung 60° on both sides of the vertical line for a total of 120°. Each swing (2 × 120 °) for about 4s;
Test time: continuous watering for 10 min
B. Nozzle type water spray test
Test equipment: hand-held water splashing test device;
Sample placement: the parallel distance between the top of the test and the nozzle of the hand nozzle is between 300mm and 500mm;
Test conditions: a baffle with a counterweight should be installed during the test, and the water flow rate is 10 L/min;
Test time: Calculated according to the surface area of ​​the shell of the sample to be tested, 1 min per square meter (excluding the installation area), at least 5 min;
IPX 4
Method Name: Splash Test
experiment method:
A, swing tube type splash test;
Test equipment and sample placement: same as the above paragraph a of IPX3;
Test conditions: except for the conditions described below, the same as the above paragraph a of IPX3; the water spray area is on both sides of the midpoint of the swing tube;
The water spray from the spray hole in the 90° arc is sprayed toward the sample. The test sample was placed in the center of the semicircle of the pendulum tube. The pendulum tube is swung 180° on both sides of the vertical line, which is about 360°; each swing (2×360°) is about 12s;
Test time: Same as the above paragraph a of IPX3 (ie 10 min);
B, nozzle type splash test
Test equipment and sample placement: same as the above paragraphs of IPX3;
Test conditions: Remove the baffle with balance weight on the equipment, and the rest are the same as the above paragraphs of IPX 3;
Test time: same as the above paragraph of IPX3, that is, according to the surface area of ​​the shell of the sample to be tested, 1min per square meter (excluding the installation area) at least 5min;
IPX 5
Method Name: Water Spray Test
Test equipment: the inner diameter of the nozzle of the nozzle is 6.3mm;
Test conditions: the distance between the test sample and the water spout is 2.5m ~ 3m, and the water flow rate is 12. 5 L / min (750 L / h);
Test time: Calculated according to the surface area of ​​the sample to be tested, 1min per square meter (excluding the installation area), at least 3 minutes;
IPX 6
Method name: strong water spray test;
Test equipment: the inner diameter of the nozzle of the nozzle is 12.5mm;
Test conditions: the test sample to the spout is 1.5m ~ 3m, the water flow is 100 L / min (6000 L / h);
Test time: Calculated according to the surface area of ​​the sample to be tested, 1min per square meter (excluding the installation area) at least 3min;
IPX 7
Method Name: Short-term water immersion test
Test equipment and test conditions: water immersion tank. The size should be such that the sample is placed in the immersion tank and the distance from the bottom of the sample to the water surface is at least 1 m. The distance from the top of the sample to the water surface is at least 0.15m; test time: 30 minutes;
Increasingly severe air pollution and decreasing forest coverage rate awaken people's environmental awareness.
At the same time, people become closer and closer to nature. This is why wood look ceramic wall tile is popular in theses days. Wood patterns tile by ink-jet technology,perfectly solving poor performance of wooden floor in moisture,abrasion and corrosion resistance.
