Appendix
The requirements of the association for standard and control and regulations of the German
chemical industries, defined in the NE21 recommendation, are partly higher compared to the
test levels and failure criteria defined in EN61326-1. For the product qualification, failure criteria
and test levels have been selected, representing always the worst case conditions.
EN61000-4, as a generic standard, defines the test setups for the specific required test for
EN61326-1 and NE21.
