Tiêu chuẩn lớp Ik là gì?

What is IK grade Standard

IK grade refers to the equipment shell anti-impact protection level, usually IK and IP protection requirements are present together, cho thiết bị điện tử ngoài trời, cho dù đó là chi phí, chôn cất hoặc vị trí ngoài trời thông thường, cần phải có IP tương ứng, Yêu cầu IK, IK level is the joule unit of the swing hammer free fall impact to determine, the specific reference standard, electrical equipment shell on the external mechanical collision of the protection level (IK code).

Ik codes are typically useful, and the protection rating is apply to the overall enclosure. Product standards should also specify the marking method that can be use in the following cases:

1. The protection level of one part of the same shell is different from that of the other.

2. The installation status will affect the level of housing protection.

What is IK Rating?

IK rating is an internationally welcome digital code. That is useful to represent the protection rating of electrical equipment housings against external mechanical collisions. According to IEC 62262:2002 and IEC 60068-2-75:1997, the protective capability of the electrical equipment housing in the event of an external force collision on the internal equipment.

IK00-No protection.

IK01-To withstand a 0.14J impact force (equivalent of 0.25KG of object falling from a height of 56mm onto the surface).

IK02-To withstand a 0.2J impact force (equivalent to 0.25KG of objects falling from 80mm high on to the surface).

IK03-To withstand a 0.35J impact force (equivalent of 0.2KG weight of an object falling from a height of 140mm to the surface).

IK04-To withstand a 0.5J impact force (equivalent to an object weighing 0.25KG falling from a height of 200mm to the surface).

IK05-To withstand a 0.7J impact force (equivalent of 0.25KG weight of an object falling from a height of 280mm to the surface).

IK06-1J impact force (equivalent to 0.25KG weight of object falling from 400mm high on the surface impact).

IK07-2J impact force (equivalent to 0.5KG weight of object falling from a height of 400mm on the surface impact).

IK08-5J impact force (equivalent to 1.7KG of objectfalling from 300mm to the surface impact).

IK09-10J impact force (equivalent to 5KG of objects falling from 200mm high on the surface impact)

IK10-20J impact force (equivalent to 5KG of object falling from a height of 400mm on the surface impact).
