适用范围：This part of EN 61935 specifies reference measurement procedures for cabling parameters and therequirements for field tester accuracy to measure cabling parameters identified in series EN 50173. Thisstandard does not apply to EN 50173-4.This International Standard applies when the cable assemblies are constructed of cablescomplying with the IEC 61156 family of standards, and connecting hardware as specified inIEC 60603-7 family of standards or IEC 61076-3-104 and IEC 61076-3-110. In the case wherecables and/or connectors do not comply with these standards, then additional tests may berequired.This standard is organized as follows:? reference laboratory measurement procedures on cabling topologies are specified inClause 4. In some cases, these procedures may be used in the field;? descriptions and requirements for measurements in the field are specified in Clause 5;? performance requirements for field testers and procedures to verify performance arespecified in Clause 6.This standard relates to performance with respect to 100 Ω cabling. For 120 Ω or 150 Ωcabling, the same principles apply but the measurement system should correspond to thenominal impedance level.Field tester types include certification, qualification and verification. Certification testing isperformed for the rigorous needs of commercial/industrial buildings to this standard.Qualification testing is described in IEC 61935-3. Qualification testing determines whether thecabling will support certain network technologies (e.g., 1000BASE-T, 100BASE-TX,IEEE 1394b1)). Qualification testers do not have traceable accuracy to national standards andprovide confidence that specific applications will work. Verification testers only verifyconnectivity.Throughout this document, 4-pair cabling is assumed. The test procedures described in thisstandard may also be used to evaluate 2-pair balanced cabling. However, 2-pair cabling linksthat share the same sheath with other links are tested as 4-pair cabling.
