This document specifies the measurement at frequencies of E2E links of two- and four-pair balanced cabling of 100 MHz of Class D and 250 MHz of Class E including free connectors which terminate two and four pairs in both field and laboratory conditions.

The specifications for E2E links are described in ISO/IEC TR 11801‑9902.

This document specifies laboratory and field measurement procedures. The requirements for accuracy to measure cabling parameters identified in ISO/IEC TR 11801‑9902 are provided in EN 61935‑1 and EN 61935‑2.
