What is BS IEC 61935‑1‑2 - Specification for the testing of balanced and coaxial information technology cabling about?
BS IEC 61935 is a series on the specification for the testing of balanced and coaxial information technology cabling. A balanced and coaxial cable utilizes that extra signal wire that carries a copy of the signal, but the two copies are sent with their polarity reversed. BS IEC 61935‑1‑2 specifies additional reference measurement procedures for the measurement of resistance unbalance with field test instrumentation, and the requirements for field tester accuracy to measure resistance unbalance according to the requirements of ISO/IEC 11801-1.
BS IEC 61935‑1‑2 specifies reference measurement procedure for resistance unbalance within a pair, between pairs, its parameters and the measurements.

Why should you use BS IEC 61935‑1‑2 - Specification for the testing of balanced and coaxial information technology cabling?
Coaxial cable is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. BS IEC 61935‑1‑2 discusses balanced coaxial cable wiring that uses two signal conductors plus a ground, allowing noise picked up along the way to be cancelled through polarity inversion. BS IEC 61935‑1‑2 specifies some extra reference measurement procedures for the measurement of resistance unbalance with field test instrumentation.
The accuracy models as described in BS IEC 61935‑1‑2 consists of the error model for DC loop resistance, error model for resistance unbalance, comparison to reference measurements and procedures for determining field tester parameters that help you measure resistance unbalance with field test instrumentation. Field test equipment is designed with two units that are attached to opposite ends of the cabling to be tested. Internal to these units are source and load ports that are used for measurements. Using BS IEC 61935‑1‑2 you can tester accuracy to measure resistance unbalance.
