IK Impact Protection Tests

IK Impact Protection Tests

European standard EN 62262 - equivalent to the international IEC 62262 (2002) standard - relates to HR ratings. This is an international numerical classification for the degrees of protection maintained for electrical equipment against external mechanical impacts. It provides a means of determining the capacity of a housing to protect its contents from external influences. The HR Code was originally defined in the European Standard BS EN 50102 (1995, 1998 was amended). Following its adoption as an international standard in 2002, the European standard was renumbered EN 62262.

IK Ratings is an international numerical classification showing the degree of protection provided for electrical equipment against external mechanical impacts. It provides a means of determining the capacity of a housing to protect it from external influences in accordance with IEC 62262: 2002 and IEC 60068-2-75: 1997.
IEC 62262: 2002 and IEC 60068-2-75: Degree of protection provided by electrical equipment enclosures against external mechanical impacts in accordance with 1997.
The "IK" rating or code is an international standard that standardizes and defines the resistance of enclosures for electronic devices to mechanical impacts, and this rating may be an important factor when selecting an outdoor camera or camera that can be installed in an area. You should also check the IP value of the equipment to check that the equipment is protected against ingress of dust or moisture.

Prior to the appearance of the IK code, a third digit was added to indicate the level of impact protection, such as IP66, with respect to the IP code for the respective protection. The non-standard use of this system was one of the factors leading to the development of this standard, and it uses two separate numerical codes to distinguish it from the old different systems. The standard came into force in October 1995 and conflicting national standards should be withdrawn in April 1997.

While the IK ratings help to classify products according to the resistance of Kinetic energy to impacts, EN 62262 shows how to mount the enclosures when testing is performed, the atmospheric conditions to be affected, the number of impacts and their (or even) the distribution, size, style of various hammer types designed to produce the required energy levels. , material, sizes etc.

Therefore, the following list shows the IK Code, the Impact Size Protection (joule), then the comments.

IK00 Unprotected

IK01 0.14 is protected against joule effect.
The mass effect of 56 kg to 0,25 mm on the affected surface is equivalent.

IK02 0.2 is protected against joule effect.
80 on the affected surface corresponded to the mass effect of 0,25 kg from mm.

IK03 0.35 is protected against joule effect.
The mass effect of 140 kg from 0,25 mm on the affected surface is equivalent.

IK04 0,5 is protected against joule effect.
200 mm on the affected surface corresponded to the effect of the mass 0,25 kg.

IK05 0.7 is protected against joules.
The mass effect of 280 kg to 0,25 mm on the affected surface is equivalent.

IK06 1 is protected against joule effect.
400 mm on the affected surface corresponded to the mass effect of 0,25 kg.

IK07 2 is protected against joule effect.
0,5 mm fell from the affected surface equivalent to the collision of 400 kg mass.

IK08 5 is protected against joules.
1,7 mm fell from the affected surface equivalent to the mass effect of 300 kg.

IK09 10 is protected against joule effect.
5 kg dropped from the surface 200 mm above the affected surface equivalent to the impact of the mass.

IK10 20 is protected against joule effect.
5 mm fell from the affected surface, equivalent to the impact of the 400 kg mass.

Basically
IK00 does not have any mechanical impact protection
IK01 Protected against an 0.15 g object dropped from 7,5 height 200 cm
02 protected against an 10 g object that is dropped between IK200 height 0,2 cm
IK03 200 protected against an object of g 0.35 17,5 cm dropped height
IK04 0.5 25 Protected against an object of 200 I height cm IK05 0.7 Protected against 35 g object whose height is less than 200 cm
IK06 Protected against the 20 g object whose height falls from 500 cm
IK07 From height 500 cm protected against falling 40 g object
IK08 1,7 Protected against a kg object. Its height is less than 29,5 cm.
IK09 10 20 Protected against the 5Kg object with a height of cm
IK10 20 40 Protected against the 5 Kg object with a height of cm
IK10 + 40 40 Against an 10 Kg object with a height of cm
