Copper channel test results are evaluated against a category standard. Standards define categories like Cat5e, Cat6, Cat6A, and so on, each with specific electrical performance limits for a completed channel. When a cabling system is tested, the measured parameters—such as insertion loss, return loss, alien crosstalk, and crosstalk between pairs—are checked against the limits in the category standard. If the results meet or exceed those limits, the channel is rated for that category, which guarantees it can support the data rates and applications associated with that category. This provides a consistent, interoperable benchmark across different manufacturers and installations.

Local building codes govern safety and installation methods; a manufacturer's specification covers a particular product’s claims rather than the overall performance benchmark for a cabling channel; safety regulations address broad safety requirements rather than performance categories.
