任何破坏性影响（喷水）。
4防止从各个方向向设备（外壳）喷水。
不允许任何破坏性影响（飞溅水）。
5防止喷嘴喷出的水喷射到设备上
（外壳）从各个方向。
不允许任何破坏性影响（喷水）

First number Protection against contact and penetration by objects 0 Little or no protection. 1 Protection against penetration by extrinsic objects with a diameter exceeding 50 mm. No protection against deliberate access, e.g., by a hand. Will keep larger body surfaces out, however. 2 Protection against penetration by extrinsic objects with a diameter exceeding 12 mm. Will keep fingers or similar objects out. 3 Protection against penetration by extrinsic objects with a diameter exceeding 2.5 mm. Keeps out tools, wiring or similar objects thicker than 2.5 mm. 4 Protection against penetration by extrinsic objects with a diameter exceeding 1 mm. Keeps out tools, wiring or similar objects thicker than 1 mm. 5 Protection against damaging dust. Complete penetration by dust is not prevented, but the dust may not be permitted to penetrate to the extent that the operation of the electrical equipment is in any way hindered (protected against dust). Complete protection against penetration by extrinsic objects. 6 Protection against the penetration of dust (dust-free). Complete protection against penetration by extrinsic objects. Second number Protection against Water 0 Little or no protection. 1 Protection against vertically dripping water (dripping or trickling water). It may not have any destructive affects. 2 Protection against vertically dripping water. It may not have any adverse affects on electrical equipment tilted up to 15° in contrast to its normal position (water dripping or trickling at an angle). 3 Penetration against water falling at an angle of up to 60°. Does not permit any damaging affects (sprayed water). 4 Protection against water sprayed at the equipment (housing) from all directions. Does not permit any damaging affects (splashwater). 5 Protection against a jet of water sprayed from a nozzle onto the equipment (housing) from all directions. Does not permit any damaging affects (jet of water)
