scope:

This part of IEC 61156 describes symmetrical pair/quad cables intended primarily for work area cabling as defined in ISO/IEC 11801 and ISO/IEC 24702. This blank detail specification includes recommended environmental characteristics and severities which are derived from the environmental classifications that are specified for cabling for various environments. The blank detail specification determines the layout and style for detail specifications describing symmetrical pair/quad cables with transmission characteristics up to the maximum frequency of the respective category for digital communications. Detail specifications, based on the blank detail specification, may be prepared by a national organization, a manufacturer or a user.
