This is a little late, but - I am the U.S. expert assigned to the maintenance team for IEC 61326-1. The disconnect in the required ESD levels for the Basic immunity environment is known. It will be resolved in the next revision of the standard - currently in progress - that should come out in late 2010 or early 2011. Unfortunately, the solution will be to increase the air discharge requirement from 4kV to 8kV to be in line with the rest of this standard as well as the generic standards.

However the level for the same test given in Table 1 which refers to Basic Immunity Requirements is only 4kV/4kV (air/contact). This seems wrong since the controlled EM environment would be inherently less severe. Does anyone else believe this to be the case?
