The IEC 62262 standard published by the International Electrotechnical Commission (IEC) describes the classification of the degrees of protection provided by enclosures against external mechanical impacts when the rated voltage of the protected equipment is not greater than 72,5 kVolts. The full name of this standard is: IEC 62262 Degrees of protection provided by electrical equipment enclosures against external mechanical impacts (IK code). This standard only applies to equipment enclosures where the specific standard specifies the degree of protection of the enclosure against mechanical impact.
Damage to enclosures can impair the proper functioning of installed equipment, such as machine control systems, or, in the worst case, render it inoperable. Therefore, enclosures must also have adequate protection against external mechanical influences. The relevant protection category is the IK code, which specifies the resistance of a housing to impacts and shocks. The IK code classification was established using a standard test method in accordance with the IEC 62262 standard.
However, in laboratory testing it may not be possible to verify the tested level of impact resistance of a housing for all points on a housing. In practice, critical points that are problematic to achieve a high IK code are often not tested. IK codes may vary according to the manufacturer's understanding of quality and the criteria they apply.
Enclosures and control cabinets are used worldwide in all conditions and must meet the strictest possible safety requirements. Protection category tests, which focus on the extent to which foreign objects and external influences can penetrate the enclosures, play an important role in this regard.
Briefly, the IEC 62262 standard defines a system for classifying the degrees of protection provided by electrical equipment enclosures against external mechanical impacts.
In the IEC 62262 standard, the impact test specifications for the 09 IK code are determined as follows:
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for the degrees of protection provided by electrical equipment enclosures against IK-09 external mechanical impacts, with its trained and expert staff and advanced technological equipment.
