LISUN IK Level Tester – After Sales Questions and Answers

The most of luminaires manufacturers are requested to do IK level test (Impact Protection). LISUN can supply the IK test instrument: IEC62262 Impact Protection Tester | IK07 to IK10 Pendulum Impact Hammer.

IK Level Tester IK07-10

IK ratings are defined as IKXX, where “XX“ is a number from 00 to 10 indicating the degrees of protection provided by enclosures (including luminaires) against external mechanical impacts. The different IK ratings relate to the ability of an enclosure to resist impact energy levels measured in joules (J). IEC62262 specifies how the enclosure must be mounted for testing, the atmospheric conditions required, the quantity and distribution of the test impacts and the impact hammer to be used for each level of IK rating. The IK test applicate on lighting luminaires test according to IEC60598 (GB7000) and IEC60068-2-75 (GB2423.55).

Q1: Composition of the complete IK device:
A1: There are ten levels of IK protection. Ik01 to Ik06 are spring hammers, and each level is an independent spring hammer. Ik07 to Ik10 are large pendulum. Four levels share a large pendulum support, and each level is equipped with a hammer head of different sizes.

Q2: IK test is a mechanical test, why does it also need power supply?
A2: IK test itself is a mechanical test and does not need to be powered on. However, LISUN has added an automatically adjustable lifting platform to the large pendulum test frame, which can automatically adjust the height of the platform according to the size of the sample. If you use this function, you need to supply power to the equipment.

Q3: How to set the hammer height?
A3: According to the impact energy required by each IK level, the hammer head and the required height are different. After selecting the corresponding hammer head and adjusting it to the corresponding height position, the IK test of this level can be carried out correctly.
For ik07 and ik10 level tests, the hammer head needs to be raised to 400mm, for ik08 level tests, the hammer head needs to be raised to 300mm, and for ik09 level tests, the hammer head needs to be raised to 200mm.
The following picture shows the setting of swing rod position during ik07 and ik10 tests. The upper edge of the slider is flush with the 400mm line.
