IP(INGRESS PROTECTION)防护等级系统是由IEC(INTERNATIONAL ELECTROTECHNICAL COMMISSION)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 drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifies electrical appliances according to their dust and moisture resistance characteristics. The IP protection level is composed of two numbers. The first number indicates the level of the appliance that is dust-proof and protected against foreign objects. In order to avoid electric shock), the second number indicates the degree of tightness of the appliance against moisture and water. The higher the number, the higher the protection level.
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 two numbers, which are used to clarify the protection level.
第一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，最高级别是6;
The first number indicates the extent to which the equipment is resistant to dust, or the extent to which people are protected from harm in a sealed environment. I represents the level to prevent solid 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，最高级别是8。The second number indicates how waterproof the device is. P stands for the level of protection against water ingress. The highest level is 8.
