In conjunction with EN116000-1:1996 this specification is the basis for qualification approval within the CECC quality assessment system in accordance with CECC00114. Howev

44、er, it is not restricted to this purpose: this specification can also be used outside the CECC quality assessment system as a general technical reference for test and measurement procedures in the field of electromechanical all-or-nothing relays. Where in this document the term “Detail Specification

45、” is used, this either has the meaning defined inCECC00114 for application within the CECC system, or it means any appropriate document,e.g.manufacturers data sheet, Test Specification, Customer Detail Specification. 1.2 Normative references This European Standard incorporates by dated or undated re

46、ference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorp

47、orated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
