scope:

This standard specifies the cable ducts to the position of the cable termination within each individual premise or house in a legal sense, however, this DS information does not specify the cable ducts for internal networks within the individual premise or house. Consequently, annex A gives proposals for this matter. The contractor of new buildings must prepare and establish the possibility for cable ducts for IT&T purposes. This concerns residential properties, business premises and institutional premises, where IT&T is expected to be installed. There may be the same need in case of a renovation of existing buildings. The guidelines in this standard are limited to apply to cable ducts for infrastructure for IT&T purposes. The size of the cable ducts must be considered to establish different types of IT&T cabling systems, e.g. systems with coaxial cables, cables with twisted pair and/or fiber optic. This standard does not specify types of cables, main distributing frames, terminal blocks, connectors, electronic equipment or other components, which can be mounted in the cable ducts.
