The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2005-03-01 latest date by which the nati
18、onal standards conflicting with the EN have to be withdrawn (dow) 2007-03-01 This Part 2-1 is intended to be used in conjunction with EN 60998-1:2004. It supplements or modifies the corresponding clauses in EN 60998-1, so as to convert it into the European Standard: Particular requirements for conne

Where this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 should be
20、adapted accordingly. In this standard, a) the following print types are used: - requirements proper: in roman type; - test specifications: in italic type; - explanatory matter: in smaller roman type. b) Subclauses and figures which are additional to those in Part 1 are numbered starting from 101; ad
