prEN 50173-20

1.1 Scope This document specifies: a) configurations of cabling which use components meeting the requirements of EN 50173-1 but which do not conform to the structure of generic cabling specified in the premises-specific parts of EN 50173-X; b) channel transmission and environmental performance requirements including those by reference to EN 50173-1. Test procedures to verify conformance of the balanced cabling configurations to the cabling transmission performance requirements of this document are provided in prEN 50697. Safety and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations. 1.2 Conformance For a cabling to conform to this document the following applies: a) The configuration and structure of the cabling conforms to the requirements of Clause 4. b) Environmental performance meets the requirements of 5.1. c) Transmission performance meets the requirements of 5.2. For balanced cabling, test methods to assess conformance with the transmission performance requirements are specified in prEN 50697. For optical fibre cabling, test methods to assess conformance with the transmission performance requirements are specified in Annexes A, B and C. d) The requirements of EN 50174 series standards and EN 50310 are met. This document provides the requirements and recommendations for testing, while the requirements for the sampling levels are provided in EN 50174-1:2018, Annex F. The test parameters to be measured, the sampling levels and the treatment of measured results to be applied for a particular installation are defined in the installation specification and quality plans for that installation prepared in accordance with EN 50174 1.
