Impact Resistance
내충격 줄(Joules) (뉴턴 미터- Nm)은 수년 동안 매우 일반적으로 사용되었습니다. 최근에는 전기 인클로저(electrical enclosures)와 캐비닛(IEC 62262:2002)에 일반적으로 사용되는 IK 등급이 등장했습니다.

Degree of protection
The International Protection (IP) classifies luminaire according to their protection against the ingress of dust, solid foreign bodies and water as an IP number system required by IEC 60529 and in accordance with IEC 60598.
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) |
