TIA TIA-455-86-A

INTRODUCTION

This method describes a procedure for determining the linear dimensional changes in extruded plastic cable jackets due to exposure at elevated temperatures while in place on a cable.

The primary use of the test procedure is evaluation of optical fiber cables. Results of this testing can inform decisions of the performance of cables in closures, connectors, or other terminations. Testing of the basic morphological changes in the extruded jacket material, independent of the cable structure, is addressed in Annex A (normative) in order to clarify the test procedures. This Annex comprises the test procedure details of the original FOTP-86.

The intent of this procedure is to determine compliance of a cable specimen at a specified temperature for a specified period of time. Users who desire to characterize the time-response of a cable specimen at elevated temperatures should consider using IEC 60794-1-22, method F11, "Sheath shrinkage (cables intended for patch cords)".
