Impact protection Testing

Impact protection is designed to protect the wearer from the effects of being hit by a falling or thrown object, or to protect them in the event of a fall or contact with the ground or some other hard object. We can provide testing and certification for a range of impact protection products to help you gain compliance, and to help you to access new markets.

IK protection test standard

Usually, the application of IK codes, the degree of protection applies to the overall housing. The IK code IK code indicates the enclosure’s level of protection against harmful mechanical collisions. The logo indicates that the enclosure is protected against external mechanical collisions using the IK code as specified below. If the relevant product committee decides to require a mark IK code, the mark requirements shall be specified in detail in its relevant product standards. The product standard shall also stipulate the marking method adopted in the following cases: 1. The degree of protection of a certain part of the same shell is different from that of other parts; 2. The installation status will affect the level of enclosure protection.

Characteristic numbers of IK codes and their definitions

Each set of characteristic numbers represents a collision energy value, the correspondence between the IK code and its corresponding collision energy. In the IEC62262 protection class code, the IK code indicates the protection level of the shell against harmful mechanical collisions to the outside world, and the characteristic number combinations are: 01 to 10, i.e.: IK01, IK02, IK03, IK04, IK05, IK06, IK07, IK08, IK09 and IK10, collision energy //J a 0.14 0. 2 0.35 0.5 0. 7 1 2 5 10 20 In these 10 levels, there are two groups of tests according to different levels of test levels: the first group is spring impact hammer test from IK01, IK02 to IK06, this group test has a smaller energy (from 0.14J to 1J); The other group is the pendulum test from IK07, IK08 to IK10, which tests with larger energies (ranging from 2J to 20J).

For example: IK10 vandal rating test refers to the shell impact resistance level of more than 10 (that is, the shell can withstand more than 20J energy 5 times, of which the same point can not be impacted more than 4 times), the application of IK code is usually, the protection level is applicable to the overall shell. If some parts of the housing have different degrees of protection, they should be marked with the corresponding degree of protection.

IEC 62262 IK protection class crash test requirements

1. Unless otherwise specified in the relevant product standards, the test should be carried out under the standard atmospheric pressure state described in GI3/T 2421-1999
2. Temperature range: 150C-350C; Air pressure: 86 kPa-106 kPa (860 mbar-1 060 mbar). When the altitude of the test site is higher than 2 000 m, it should be adjusted to the necessary drop height to obtain the specified collision energy.
3. Shell under test Unless otherwise specified in the relevant product standards, all shells under test should be clean, new and complete shells, and all components should be installed in place.
