How to make street light housing protection grade IK10, how much is the test cost of street lamp IK10
IK code (IK code) indicates the level of protection of the enclosure against external harmful mechanical impact. Indicates the shell to the outside mechanical collision protection grade, the application of IK code for the characteristic number combination (00 to 10).
IK quasi-applicable to the rated voltage does not exceed 72. 5 kV of electrical equipment shell to the outside mechanical collision protection classification, only for the outside mechanical collision protection classification has special requirements of the shell.
IK protection level test
IK protection grade test generally through the pendulum, spring hammer and vertical drop hammer three test devices to achieve the required collision energy, according to the size of the collision energy is divided into the following twelve expressions (the severity level in increasing order).
In accordance with GB/T20138-2006/IEC62262;2002 electrical equipment shell to the outside mechanical collision protection grade, this standard is only applicable to the outside mechanical collision protection classification of the shell with special requirements.
Application of IK code Usually, the protection class applies to the overall shell. If some parts of the shell have a different level of protection, the corresponding level of protection should be marked. If the relevant product committee decides to require the marking of the IK code, the marking requirements should be specified in detail in its relevant product standards.
Product standards should also specify the marking method used in the following cases:
1. The protection level of one part of the same enclosure is different from other parts;
2. The state of installation will affect the level of protection of the enclosure.
IK test standard:
IEC62262: Specify how to install the test object, ventilation requirements, the number and distribution of impact hammers and the corresponding impact hammers for each class when doing IK protection level testing
In IEC62262 protection class code, IK code indicates the level of protection of the enclosure against external harmful mechanical impact, the combination of the characteristic numbers: 01 to 10, namely: IKO1, IK02, IK03, IK04, IK05, IK06, IK07, IK08, IK09 and IK10.
Within these 10 levels, there are two groups of tests depending on the level of testing:
The first group is the spring-loaded impact hammer test from IK01, IK02 to IK06, which has a smaller energy (from 0.14 J to 1 J);
The other group is the large pendulum test from IK07, IK08 to IK10, whose test energy is larger (ranging from 2J to 20J).
Note 1: If higher collision energy is required, the recommended value is 50J,
Note 2: Some national standards use a number to indicate the specified collision energy, in order to avoid confusion, so the characteristics of the number of two numbers to choose
The purpose of the test is mainly to test whether the level of protection of the lighting product shell to meet the industry and national requirements.
