IS-43-1987 Local Area Network Twisted Pair Data Communications Cable Adopted for Use in the U.S. National Electronic Components Quality Assessment System (NECQ-System)
This Omnibus Specification relates to Local Area Network Twisted Pair Cable constructed of insulated copper conductor pairs in a single PVC or fluorocarbon jacket. The cable is intended for use with local area networks such as token ring networks and other systems employing similar technology as a total building wiring system. The purpose of this standard is to: 1. Establish uniform requirements and test methods for characterizing geometric@ mechanical@ environmental@ and transmission properties of Local Area Network Cable. 2. Prescribe preferred ratings and characteristics and to select from this standard the appropriate test and measurement methods to provide a fixed sample Component Qualification Approval test schedule. Individual cables shall be described in relevant Detail Specifications that will reference this Omnibus Specification.
