ip防水等级（IP waterproof rating）

ip防水等级（IP waterproof rating） ip防水等级(IP waterproof rating) IP grade (dustproof, waterproof) definition [entry: power169 | time: 2006-12-16 23:14:59 | Author: | source:] [last article] [next article] The IP rating system provides a dustproof, electrical equipment and packaging of waterproof and anti collision degree to classify the products, this system has been recognized by most European countries, and in the IED529 (BS EN 60529:1992) package protection level (IP code) announced. The level of protection is followed by two numbers followed by IP. The numbers are used to specify the level of protection. The first figure shows the range of equipment against dust, or the extent to which people protect themselves from damage in a sealed environment. Second safety words indicate the degree of water resistance of the equipment. Digital first digit - dustproof, second numbers - Waterproof 0 no protection, no protection 1 can resist more than 50mm of solid material. Such as: hands accidentally touched, can withstand vertical water drop point. 2 can resist the diameter of more than 12mm diameter, length of not more than 80mm of solid material. Such as: fingers can withstand 15 degrees vertical angle of the direct injection of water spray. 3 resistant to solids over 2.5mm in diameter. A tool or wire that can withstand direct spraying of a spray at a vertical angle of 60 degrees. 4 resistant to solids over 1.0mm in diameter. Small wires, for example, can withstand spray in any direction - allowing limited access. 5 dustproof, limited access (without harmful accumulation). A low-pressure jet of water from any direction allows limited access. 6 dust difficult to enter, completely dustproof. Capable of being subjected to a powerful jet of water from any direction - allowing limited access. 7 is not applicable. Allow brief 0.15m 1m deep water for up to 30 minutes. 8 is not applicable. Can withstand long-term immersion under pressure. Recognize the waterproof grade JIS (IPX) of electronic products ________________________________________ Editorial Center Waterproof grade of electronic measuring instruments and also reflects the ability of the instrument to dust and moisture resistant, especially for outdoor activities, not in the rabbit high humidity or more dust in the hostile environment of the instrument for sealing and waterproofing ability to ensure safe operation and service life of the instrument is crucial. To this end, international standards for the formulation of IEC529. In order to adapt to this, Japan's industrial standards will be electronic instruments waterproof protection is divided into 10 grades, respectively, IPX1, IPX2...... Express。 Protection level, category, meaning 0 no protection 1 anti drop I vertical drop of water droplets without harmful effects 2, anti drop II and vertical direction into 15 "within the range of falling water droplets, there is no kiln." 3, rain and vertical direction within 60 degrees rain, no guest influence 4 splash splash in any direction without harmful effects 5, anti injection in any direction directly by the water jet, no harmful effects 6 water resistance, arbitrary direction, directly by the water jet, also does not speak of people inside 7, anti immersion type under the prescribed conditions, even if immersed in water, not all within 8 water immersed for a long time in a certain pressure of water can still use 9 moisture proof type, which is used at 90% humidity of relative humidity International industrial standard waterproof registration IP and Japanese industrial standard JIS waterproof level is close, 0-8 of the 9 grade, IP grade is also made for dust. IPxx dust proof and waterproof grade Dust rating (first X indication) waterproof level (second X stands) 0: there is no protection 1: to prevent large solid invasion 2: prevent medium size solid intrusion 3: prevent small solids from entering the invasion 4: prevent objects larger than 1mm solid access 5: to prevent harmful dust accumulation 6: completely prevent dust entering 0: there is no protection 1: water droplets drip into the casing without affecting 2: when the case is tilted to 15 degrees, the water droplets drip into the casing without affecting 3: water or rain from the 60 degree corner to the shell has no effect 4: liquid poured in any direction to the shell, no harm 5: rinse with water without any harm 6: can be used in cabin environment 7: resistant immersion in a short period of time (1m) 8: for a long time under certain pressure flooding Example: there is a scale or display instrument marked "IP65", which means that the product can completely prevent dust entry and water flushing without any harm. Regulations on waterproof experiment in grade IPXX.
