BS PD CLC/TR 50174-99-1:2015 defines requirements and recommendations concerning limits for theapplication and operation of remote powering using cabling comprising balanced cablingcomponents of Category 5 and above as defined in EN 50173-1.This Technical Report also describes:

• a set of specific implementations which are the basis of a mathematical model for thetemperature increases in bundles of cables under remote powering conditions;
• a matching testing protocol used to provide data for the mathematical model;NOTE The testing protocol was established in order to enable comparison of data from different sources in orderto support the development of the mathematical model and to develop appropriate planning and installation rules assuggested by different installation conditions. It is not the role of CLC/TC 215 to develop test methods for balanced,or other, cables and the protocol defined in Annex B is not as such a test method.
• the mathematical model that is employed as the basis for the resulting requirements andrecommendations.

Safety (electrical safety and protection, optical power, fire, etc.) and electromagneticcompatibility (EMC) requirements are outside the scope of this Technical Report and arecovered by standards and regulations. However, information given in this Technical Report maybe of assistance in meeting these standards and regulations.Cross References:EN 50173EN 50173-1:2011EN 50174EN 50174-2:2009+A1:2011+A2:2014EN 50173-2EN 50173-6EN 50174-1EN 60512-99-001IEC 60512-99-001EN 60512-9-3IEC 60512-9-3EN 60950IEC 60950ISO/IEC TR 29125:2010IEEE 802.3:2012
