IP防尘防水等级如何申请办理
IP(INGRESS PROTECTION)防护等级系统是由IEC(INTERNATIONAL ELECTROTECHNICALCOMMISSION)所起草，将电器依其防尘防湿气之特性加以分级。IP防护等级是由两个数字所组成，第1个数字表示电器防尘、防止外物侵入的等级(这里所指的外物含工具，人的手指等均不可接触到电器之内带电部分，以免触电)，第2个数字表示电器防湿气、防水浸入的密闭程度，数字越大表示其防护等级越高。
The IP (INGRESS PROTECTION) protection level system was draftedby IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), whichclassifies electrical appliances according to their dust andmoisture resistance characteristics. The IP protection level iscomposed of two numbers. The first number indicates the level ofthe appliance that is dust-proof and protected against foreignobjects. In order to avoid electric shock), the second numberindicates the degree of tightness of the appliance against moistureand water. The higher the number, the higher the protectionlevel.
防护等级多以IP后跟随两个数字来表述，数字用来明确防护的等级。
The protection level is mostly expressed by IP followed by twonumbers, which are used to clarify the protection level.
第1个数字表明设备抗微尘的范围，或者是人们在密封环境中免受危害的程度。I代表防止固体异物进入的等级，高别是6;
The first number indicates the extent to which the equipment isresistant to dust, or the extent to which people are protected fromharm in a sealed environment. I represents the level to preventsolid foreign matter from entering, the highest level is 6;
第二个数字表明设备防水的程度。P代表防止进水的等级，高别是8。The second number indicates howwaterproof the device is. P stands for the level of protectionagainst water ingress. The highest level is 8.
