What is Severity Test A and B for ASSEMBLY ?
Severity Test for Assembly is Degree of impact a defect has on its operation, under conditions of high humidity combined with cyclic changes in temperature.

Clearance is the shortest distance in air between two conductive parts. Minimum Clearance required to withstand transient overvoltages as per IEC 61439.
Tested Assemblies Varification Tests as per IEC 61439. Verification by TESTING, CALCULATION, DESIGN-RULES for Construction and Performance of ASSEMBLY.
IEC 61439, Low Voltage Power Switchgear and Controlgear ASSEMBLIES. Discrimination between TTA and PTTA eliminated by verification approach.
