  • 3.5 Introduction of IP Rate and way of testing
    Instruction of IP (Conform EN60529/IEC529) Instruction of protection Level (according to EN60529/IEC529) For example: Traffic Lights Protection level IP54, IP is the mark, number 5 is the first marking number, 4 is the second marking number, the first marking number means the contact potection level, the second mark number means the water proof level, contact protection and anti external force (first number) water-proof level(second number). First number protection area Name description: 0 no protection 1 protection from 50mm diameter and big thing. Diameter 50mm. No damage from the vertical dropping water 2 protection from 12.5mm diameter and big external thing. Diameter 12.5mm. No damage from the dropping water for an angle of 15 degree. No damage from the vertical droping water. 3 protection from 2.55mm diameter and big external thing. Diameter 2.5mm. No damage from the dropping water with angle 60 degree. 4 protection from 1.0mm diameter and big external thing. Diameter 1.0mm. No damage from the dropping water with any angle 5 Anti dust, impossible complete anti dust. But no damage to the equipment. 6 Anti dust, with an air compress of 20mpa, no dust can enter the cabinet. water pull from every angle can not cause any damage. No enter of the detector into the cabinet. Short time water proof when drank in the water. 8 Protection long time water drank. Water drank under certain condition. The volumn should not exceed a certain quantity which can cause a damage. Second number protection area, Water proof test 1. Area: Waterproof test should include the second digit from 1 to 8, which protection level is 1P x 1 to IP x 8 2. Experiment content for protection of different level. (1)IPX1 Method: vertial vater dropping experiment. Experiment equipment: water dropping experiment equipment and its experiment method. Please refer to 2.11. Sample mounting: put it on the normal position on the rotating sample position(1r/min). the distance between the water dropping place and the sample top should not exceed 200mm. Experiment condition: droping volume is 0.5 mm/minute Lasting time: 10minutes (2)IPX2 Method: 15degree water dropping experiment Experiment equipment: water dropping experiment equipment and its experiment method. Please refer to 2.11. Sample mounting: put one side of a cabinet to be 15 degree vertically. The distance between the water dropping position and sample top should not exceed 200mm. Change one side after finished one side. Totally 4 times. Test condition: water drop 0.5mm/min Test time: 4 x 2.5minutes(total 10 minutes) (3)IPX3 Method: water sprinting experiment a. Throwing water springting experiment. Test equipment: throwing water spraying experiment equipment( please reafer chapter 2.14 for the drawing and method) Sample mounting: choose tube with proper diameter. Put the sample on radius of the mounting place. Make sure the distance between the sample and the spray head not exceed 200mm. No rotation. Test condition: over flow rate: each output 0.07L/min. when spray water, from the middle point , with an angle of 60degree. The sample was mounted on the middle of the circle. Constant water springting for 10 minutesb. Sprining water experiment Equipment: manual water sprinting equiment, please refer to the chapter 2.14 in this book. Sample mounting : the horizental distance between the top and the hand is 300mm to 500mm. Experiment condition: must install a board with a balance for weighing, water flow is 10L/minutes Experiment time: calculated according to the area of the cabinet shell. 1min per sqm( not include the installation area. (4)IPX4 Method: water pulling test Thriving water pulling test Equipment and sample position: same as the 3 above Experiment condition: same as the condtion a of 3 IPX3. The spring area is with a 90 degree angle, then spring to the ample which is mountintg in the middle of the circle. Experiment time: same as the number 3 and a of IPX 3 ( 10minutes) (5)IPX5 Method: water spring experiment Experiment Equipment: diameter of spring tube is 6.3mm, refer to 2.14 in this book Experiment condition: distance from the sample to the tube is 2.5-3m the water flow is 12.5L/minute Experiment time: according to the area of the cabinet shell. 1min/sqm (not include the installation area) at least 3 min. (6)IPX6 Method: high instensity water springing experiment Experiment Equipment: diameter of water tube is 12.5mm, refer to the 2.14 chapter Experiment: distance from the sample to the tube is 2.5-3m the water flow is 100L/minute (7)IPX7 Method: short time water drank experiment Experiment equipment, condition: water tank, distance from the bottom of sample to the surface of the water should be 1m at least. Experiment time: 30min (8)IPX8 Method: constant water drank experiment Experiment equipment, condition and time: negotiable by both side. Higher demand than IPX7
