Hi, Cenelec Guide 25 answers this in its Clause 4 (k):
When there is an undated reference to a basic standard, then either the latest edition or (if the date of withdrawal of conflicting standards associated with the latest edition has not expired) the superseded edition may be applied. After the date of withdrawal, the latest edition shall be applied. So it's the #2 in your question. Regards, Ari Honkala SGS Fimko, Finland From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: 15. huhtikuuta 2009 3:52 To: [email protected] Subject: EN 60601-1-2 and Annex ZA To all: I'm reading EN 60601-1-2:2001, and I'm not clear on a sentence in Annex ZA. It says: "For undated references the latest edition of the publication referred to applies (including amendments)." 1) Is it the 'latest edition' when EN 60601-1-2:2001 was published? The annex lists the valid edition at that time. For example, EN 61000-4-4:1995 2) Or is it the 'latest edition' at the time the system is tested? In this case, EN 61000-4-4:2005 Pat Lawler EMC Engineer SL Power Electronics Corp. - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
