IEEE 1242-1999 pdf download IEEE Guide for Specifying and Selecting Power, Control, and Special-Purpose Cable for Petroleum and Chemical Plants
1. Overview
1.1 Scope This guide provides information on the specication and selection of power, control, and special-purpose cable, as typically used in petroleum, chemical, and similar plants. It addresses materials, design, testing, and applications. More recent developments such as strand lling, low-smoke, zero-halogen materials and chemical-moisture barriers have been included. This guide is not intended to be a design document, although many of the problems associated with the specication and selection of power, control, and special-purpose cable for petroleum and chemical plant applications can be avoided by considering the information presented in this guide. It is recognized that there may be other types of cable used in the petroleum and chemical industries, especially considering the global marketplace. This guide should not be interpreted as precluding the use of such cables.
1.2 Purpose The purpose of this guide is to provide the user with cable designs, applications, and test procedures that are common to the petroleum, chemical, or similar type of industry. It is intended as an informational tool for the new as well as the more seasoned engineer. In this capacity, it contains an extensive single-point refer- ence and cross-reference list of standards as they apply to the wire and cable industry, including U.S. and Canadian standards. It provides application guidelines for the type of installations found in petroleum and chemical plants as they relate to electrical, mechanical, physical, thermal, and environmental properties of the cable. The use of this guide should help to eliminate premature cable failure due to improper specica- tion, selection, and application of cable in petroleum and chemical plants.

3.1 General comments
This clause provides basic information on power and control cables that are typically utilized in petroleum and chemical plant applications. It is not intended to duplicate information contained in the references listed in Clause 2. Accordingly, listing of other sources of information is emphasized. Considerable reliance is placed on illustrations and photographs of typical cables that are not included in other references. Construction details, applicable standards, and application information are included with each gure. Also note that the illustrative information does not include all cables used in petroleum and chemical plants. Not included in this clause are instrument cables, communication cables, portable cords, preassembled aerial cables, submarine cables, mineral insulated cables, jumper cables, etc. Information on such special-purpose cables can be obtained from Clause 12 of this guide and from the documents listed in Clause 2 and Annex A. Also, refer to Clause 4 for general information on cable application and specically to 4.4.2 for further infor- mation on ame rating.\
