多年来
焦耳(牛顿-米)的使用一直很普遍。最近,一种通常用于电气外壳和机柜的IK等级(IEC 62262:2002)出现了,因为制造商将它应用到灯具上,因为它们做了电路封闭保护。

IP 等级
根据IEC 60529和 IEC 60598 的要求,国际灯具保护组织(IP)将灯具按照其防尘、防固体异物和防水侵入的IP编码系统进行分类。
Protection from solids (First number)
IP1x | Protection against solid objects of 50 mm. diameter and greater than 50 mm. |
IP2x | Protection against solid objects of 12 mm. diameter and greater than 12 mm. |
IP3x | Protection against solid objects of 2.5 mm. diameter and greater than 2.5 mm. |
IP4x | Protection against solid objects of 1 mm. diameter and greater than 1 mm. |
IP5x | Complete protection against solid objects and harmful dust deposits (dust-proof) |
IP6x | Complete protection against dust entry (dust-tight) |
Protection from water (Second number)
IPx1 | Protection against vertical dripping water |
IPx2 | Protection against dripping water when tilted up to 15° from vertical |
IPx3 | Protection against spraying water or falling rain up to 60° from vertical |
IPx4 | Protection against splashing water from any direction (splash-proof) |
IPx5 | Protection against water jets from any direction (jet-proof) |
IPx6 | Protection against heavy seas or powerful water jets |
IPx7 | Protection against immersion (water-tight) |
IPx8.m | Protection against submersion (submersion-proof) |
