There are specific requirements for cabling systems that are in accordance with the design requirements of the EN 50173 series. However, the three parts also apply to cabling
14、 systems of any design including those in accordance with standards such as EN 50098-1 or EN 50098-2.This part, EN 50174-1, is concerned with specification, quality assurance, documentation and administration of information technology cabling to be installed, together with its subsequent operation a
15、nd maintenance. It sets out the responsibilities of information technology cabling installers and premises owners or appointed representatives separately, and is intended to be referenced in relevant contracts.It does not cover those aspects of installation associated with the transmission of signal
16、s in free space between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or satellite).BS EN 50174-1:2009EN 50174-1:2009 47 ContentsIntroduction. 51Scope and conformance. 81.1Scope . 81.2Conformance. 82Normative references. 83Terms, definitions and abbrevi
