To answer the question regarding relaxation of test levels in EN 61326,
there is no relaxation of the rf-immunity test levels for the ITU
frequencies (or any frequency) as was the case with the generic standards.

Responding to Ian Unwin's question regarding future direction of IEC 61326,
the proposal within IEC at the moment for the radiated-rf immunity test is
10 V/m (80 MHz-1 GHz), 3 V/m (1,4 GHz-2 GHZ), 1 V/M (2,0-2,7 GHz). Note
that these are the proposed industrial environment limits (currently

The exclusion of harmonic test requirements in EN 61326 for equipment which
need only meet Class A emission limits was a deliberate decision by the
authors. It was not an omission by error. Many outside the committee now
view this decision as a mistake.
There is no revision in progress.
Eric Lifesey nicely summarized the requirements of IEC (also EN) 61326 in his
e-mail copied below. I would like to add however that harmonics are indeed
covered in the emission section of the standard. The emission
limits as listed in Table 4 for Class B (non-industrial locations) include
This may provide some of the answers to Jason Chesley's questions on EN
61326-1.
The DOW as stated in EN 61326-1 (1997) has no relevance with regard to
CE-Marking since I don't believe this standard is yet listed in the OJ. In
my view, the delay in seeing the standard listed is linked to the
The sub-parts of 61326 are: General Requirements (This includes
immunity and emissions), Annex A: Immunity test requirements for
equipment intended for use in industrial locations, Annex B: Immunity
test requirements for equipment used in controlled EM environments (This
covers laboratories),
