12、08-05-01. This European Standard supersedes EN 61810-1:2004. The relevant modifications compared to EN 61810-1:2004 are: update of references; renumbering of clauses to bring them into a more logical order; inclusion of contact load categories (same as in EN 61810-2 and EN 61810-7); clarifications c
13、oncerning electrical endurance (Clause 11); inclusion of provisions for insulation coordination in accordance with the basic safety standards EN 60664-3, EN 60664-4 and EN 60664-5 (Clause 13); renumbering of all annexes in the order they are referenced in the body of the standard; inclusion of new A
14、nnex C (normative) for the test set-up, and new Annex D (informative) for special loads (based upon similar annexes in EN 61810-2 and EN 61810-7); improvement of Annex B covering inductive contact loads.
