Those

26、 standards have requirements to ensure that models work for generic cabling and system performances. Values in this standard support these models. The requirements of the family specification IEC 60794-3-10 are applicable to cables covered by this standard. Particular requirements detailed in Clause

27、 4 of this standard either define a specific option relative to the requirements of IEC 60794-3-10 or define additional requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated

28、references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. NOTE These references complete the normative references already listed in the generic specifications IEC 60794-1-1 and IEC 60794-1-2, in the sectional

36、 Annex B (Multimode fibre sub-category A1b, 62,5 m core diameter). To ensure compatibility with ISO/IEC 11801 and ISO/IEC 24702, optical performance level requirements are presented in terms of the performance classification codes as follows: OS1 Single-mode fibre categories B1.1, B1.3 or sub-catego

37、ries B6 a1, B6 a2; OS2 Single-mode fibre category B1.3 or sub-categories B6 a1, B6 a2; OM1 Multimode fibre sub-categories A1a, A1b; OM2 Multimode fibre sub-categories A1a, A1b; OM3 Multimode fibre model A1a.2; OM4 Multimode fibre model A1a.3. NOTE These codes are informative from the perspective of

38、the requirements defined in this detailed specification. 4 Particular requirements General 4.1These requirements either define a specific option relative to the requirements of IEC 60794-3-10 or define additional requirements. MICE (mechanical, ingress, climatic and chemical and electromagnetic) 4.2

39、characteristics Cables intended for installation in conformity with ISO/IEC 24702,and related standards, may require the specification of additional tests to ensure their suitability in the applicable environments defined by the mechanical, ingress, climatic and chemical and electromagnetic (MICE) c

40、lassification. Such tests are outside the scope of IEC 60794 cable specifications, and MICE criteria are not part of the requirements for IEC 60794 specifications. The MICE tests may be the same as, similar to, or substantially different from, the tests required by IEC 60794 specifications. Cables m

41、anufactured per IEC 60794 specifications may or may not meet the MICE criteria. For supplemental discussion see IEC/TR 62362 12. _ 2Numbers in square brackets refer to the Bibliography.
