Standards Standards governing the design, installation, commissioning and operation of structured cabling systems, and the particular environments they operate within can be complex and confusing. There are 3 main standardisation bodies across the world and depending on where the installation takes place; they have an order of precedence. International The Joint Technical Committee 1 (JTC1) of the International Organisation for Standardisation (ISO) and the International Electrotechnical Commission (IEC) is the main body for producing such standards. IEC provides the interface, performance and test standards for components. ISO IEC Europe The European Committee for Electrotechnical Standardisation (CENELEC) is the overall authority for the production of standards within Europe. Various national committees also exist in many of the European countries and may take their national standards from any of the larger standards bodies. National standards are not allowed, where European standards exits. The countries have to adopt the normative European standards (EN). CENELEC North America TIA In North America (including Canada), the Telecommunications Industry Association (TIA) is the relevant standardisation body, although the structure of its standards is slightly different (and in some cases deviating) to that of ISO, IEC and CENELEC. There is extensive harmonisation between CENELEC, ISO and IEC standardisation bodies, although some of the differences with TIA are in the exact wording, designation and structure used. However TIA harmonises standards with ISO and IEC wherever it is possible. HUBER+SUHNER is a global company, supplying a globally-suitable product, which references international standards component compliance as a 1st preference. However, the precedence of local standards is typically most relevant in the design and installation requirements rather than components that a manufacturer may supply, and typically will reference the same international component standards. If there is any doubt on the standards compliance to any local standard, please contact your local application engineer who will be able to clarify the situation. HUBER+SUHNER Data center 223
