What is the IK code (Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts )? According to IEC62262 standard, it refers to 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 72.5KV. It use the IK code to indicate the degree of protection provided by an enclosure against harmful external mechanical impacts. In cases where the relevant product committee decides that the marking of the IK-code shall be required, the marking requirements shall be detailed in the relevant product standard. Where appropriate, such a standard should also specify the method of marking which is to be used when - one part of an enclosure has a different degree of protection to that of another part of the same enclosure - the mounting position has an influence on the degree of protection. The degree of protection provided by an enclosur...

 In order to evaluate the fire hazard of electrical and electronic products, it is necessary to conduct flame hazard  tests on the components and materials of electronic and electrical products. The common flame hazard tests include needle flame test, glow wire test, and horizontal and vertical flame test, so what’s the difference between them?   1.  Standard is different 1)  The needle flame test is designed according to IEC60695-11-5 <<Test flames -Needle flame test method - Apparatus, confirmatory test arrangement and guidance>>. 2)  The glow wire test is carried out in accordance with IEC60695-2-10 <<Glowing/hot-wire based test methods - Glow-wire apparatus and common test procedure>>. 3)  The horizontal and vertical flame test is carried out according to UL94, IEC60695-11-10 <<Test flames - 50W horizontal and vertical flame test methods>>.   2.  Testing method 1)  Test method of Needle fl...
