30、es and structures of fibres and cables. It includes: connector set requirements; This part of IEC 60874 is divided into four clauses: Clauses 1 (Scope), 2 (Normative references) and 3 (Terms and definitions) contain general information pertaining to this generic specification; Clause 4 (Requirements
31、) contains all the requirements to be met by connectors covered by this specification. This includes requirements for classification, the IEC specification system, documentation, materials, workmanship, quality, performance, identification, and packaging. NOTE 1 Clauses 1 to 4 are applicable general
32、ly and refer to all connector standards NOTE 2 This part of IEC 60874 applies also to the connectors covered by the IEC 61753, IEC 61754, and IEC 61755 series. This standard does not cover test and measurement procedures, which are described in the IEC 61300 series. 2 Normative references The follow
