Thanks to Doug Frazee for pointing out that AC Harmonics and Flicker ARE in IEC 61326-1 (contrary to my previous comment), but only as a requirement for Class B emissions.
These tests are tucked into the emission limits table (Table 4 on page 29) and buried between the typical emission limit data. It would have been helpful if it was listed in it's own table, owing to how unique it is compared to the more common CISPR 11/22 emission standards insofar as test setup goes. Another clue was that these standards were listed in the normative reference as well. So, Class A has another advantage over Class B.

It calls out a mandatory test plan containing: EUT test configuration, operating conditions, performance criteria and test descriptions. Immunity requirements are: 1000-4-2, -3, -4, -5, -6, and -11. Test levels are in line with the current generic light industrial immunity standard. Emissions limits are identical to CISPR22 for Class A/B equipments, however class B equipments require 1000-3-2 and 1000-3-3 (low freq. powerline harmonics/flicker); discontinuous interference per CISPR14 for Class B equipments if appropriate. The specification is specifically geared towards measurement, control and lab. equipment and will be mandatory for these equipments, eventually. It will be significantly more expensive to test to due to additional test requirements and the mandatory test plan. As far as dates, I as well am trying to find out. Global Engineering Documents does not yet have the EN in stock. Anyone know the dop and dow? Doug Frazee EMC Compliance Engineer Alliant Techsystems, Inc.
