37、s foreword is not considered part of this Standard.) This Standard was developed by TIA Subcommittee TR-42.1. Approval of standard This Standard was approved by TIA Subcommittee TR-42.1, TIA Engineering Committee TR-42, and the American National Standards Institute (ANSI). ANSI/TIA reviews standards
38、 every 5 years. At that time, standards are reaffirmed, withdrawn, or revised according to the submitted updates. Updates to be included in the next revision should be sent to the committee chair or to ANSI/TIA. Contributing organizations More than 60 organizations within the telecommunications indu
39、stry (including manufacturers, consultants, end users, and other organizations) contributed their expertise to the development of this Standard. Documents superseded This Standard replaces ANSI/TIA-862-A dated April 2011. Significant technical changes from previous edition Significant technical chan
40、ges from ANSI/TIA-862-A include: null Change of title (was Building Automation Systems Cabling Standard). null General substitution of the term “intelligent building system” for the previous term “building automation system.” null Updating of references. null Addition of guidance for cabling for: o
