When the this distinction between dated AND undated references is so clearly made (as in EN 61326-1:2013) this SHOULD mean that once an undated reference is found, it should definitely be read as undated.
If a standard is to be applied in full, that means it should also include the presumed errors.... until a correction is published. I agree with you (John), that probably the intention of the committee was to give dated references only, and that section ZA and 2 are explicitly meant to define this (sec 2 created by IEC, ZA created by CENELEC) . The standards text (apart from ZA) should then refrain from dated references at all or use some kind of index number to annex ZA when a standard is referred. And it's a shame that CENELEC (as the latest responsible in the chain) is so careless in their published texts. Regards, Ing.

It isn't clear whether a reference can be dated in some places in the text and dated in others. In my opinion, if it's dated in Clause 2 Normative references it is dated throughout the document.

Par 7.2 also refers to CISPR11:2009 . The limit references for Class A and B do not refer to a dated CISPR11 While I am convinced this is the kind of carefulness that is common in standards published by IEC and CENELEC, the normative consequences are that the latest versions apply. So yes, since the publication date of June, 26th 2016 this new version : Allows for FAR room measurements Prescribes limits for DC in/output ports and defines the delta LISN type to be used: "For measurements at LV d.c. power ports of power electronic equipment, a modern implementation of the 150 Ω Delta-network specified in CISPR 16-1-2 has been made available" Regards, Ing.

From: Paolo Roncone [mailto:paoloc...@gmail.com] Sent: Monday 28 November 2016 10:25 To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] DC-power conducted emissions per CISPR11: 2016 Hi all, the new 2016 edition of CISPR11 requires DC power ports conducted emissions to be done with a "150 Ohm CISPR Delta-network (DC-AN) – see CISPR11 ed.6.1 (2016) sec. 6.2.1.3, 7.3.2.3 and Annex I) instead of a "standard" 50uH/50ohm V-LISN, used for AC-power conducted emissions and also for AC&DC power conducted emissions according to IEC/EN 61000-6-3, CISPR22 and other standards. That means - to my understandiing - that DC-powered Laboratory equipment (tested per IEC/EN 61326-1, sec. 7.2) and Medical devices (tested according to IEC 60601-1-2 (sec.7.1.1) must be tested with the Delta-LISN for DC-power conducted emissions. Is my understanding correct?
