scope:

This part of IEC 61935 specifies reference measurement procedures for cabling parameters and the requirements for field tester accuracy to measure cabling parameters identified in ISO/IEC 11801. References in this standard to ISO/IEC 11801 mean ISO/IEC 11801 or equivalent cabling standards. This standard applies when the cable assemblies are constructed of cables complying with IEC 61156 -1, IEC 61156-2, IEC 61156-3 IEC 61156-4, IEC 61156-5 or IEC 61156-6, and connecting hardware as specified in IEC 60603-7 or IEC 61076-3-104. In the case where cables and/or connectors do not comply with these standards then additional tests may be required. This standard is organized as follows: - reference laboratory measurement procedures are specified in Clause 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 are specified in Clause 6.
