How to conduct the ESD test?

  What is ESD test? Electrostatic discharge immunity test is a basic EMC test . S tandard IEC61000-4-2 provide the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and to adjacent objects . T he standard establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. Electrostatic discharge is a transfer of electric charge between bodies of different electrostatic potential in proximity or through direct contact. The standard IEC61000-4-2 does not intend to specify the tests to be applied to particular apparatus or system, it is to give a general basic reference to all concerned product .   S o before conduct the test, an appropriate test level should be selected according to the product's characters and its working occasion.   Contact discharge and air discharge methods The test leve...

The relationship between standards IEC62262 and IEC60068-2-75

  The IK code is a coding system to indicate the degree of protection provided by an enclosure against harmful external mechanical impacts. The standard IEC62262 defines the impact energy corresponding to different IK codes. In general, the degree of protection applies to the complete enclosure. If parts of the enclosure have differing degrees of protection, the latter shall be indicated separately. IK00 IK01 IK02 IK03 IK04 IK05 IK06 IK07 IK08 IK09 IK10 IK11 0 0.14J 0.2J 0.35J 0.5J 0.7J 1J 2J 5J 10J 20J 50J IK00 - no protection IK01 - withstands 0.14J impact force (equivalent to the impact of an object weighing 0.25KG falling from a height of 56mm on the surface) IK02 - Withstand 0.2J impact force (equivalent to the impact of an object weighing 0.25KG falling from a height of 80mm on the surface) IK03 - Withstand 0.35J impact force (equivalent to the impact of an object weighing 0.2KG falling from a height of 140mm on the surface) IK04 - Withstand 0.5J impact force (equivalent to t...
