Compatibility is established by placing component samples in contact with the cleaning solvent for a short period and then measuring the physical or electrical properties of th

Introduction This introduction is not part of IEEE Std 1493-2006, IEEE Guide for the Evaluation of Solvents Used for Cleaning Electrical Cables and Accessories. This guide provides test methods and general evaluation cr

8、iteria used to judge the efficacy of electrical cable cleaning solvents proposed as replacements for environmentally harmful and soon to be unavailable chlorinated hydrocarbons such as trichloroethane. The conformance of a product to the proposed requirements for replacement solvents suggests the pr

9、oduct should be acceptable for use as an electrical cable cleaning solvent. Solvents have been used by the electrical industry for numerous applications for many years. Most applications require the solvent meet special requirements such as fast evaporation rate, high dielectric strength, and compat

10、ibility with semiconductive polymeric materials. For several decades, one family of solvents has been universally used by the electric industry for nearly all of its applications. This family of chemicals is referred to as chlorofluorocarbons (CFCs), which are a unique class of compounds. One CFC co

11、mpound, trichloroethane, proved to be ideal for electrical cable cleaning by the electric industry because it has a very high flash point, high dielectric strength, evaporates quickly, and cleans effectively. Trichloroethane and most other members of the CFC family have been slated for a production

12、and use phase-out because of concern over the depletion of the ozone layer in the upper atmosphere. Production of trichloroethane in the United States was halted on January 1, 1996. It has been heavily studied and well documented that CFCs rise to the upper atmosphere and react with upper level ozon

13、e, which causes the concentration of ozone to be substantially reduced. Reduced levels of upper level ozone are projected to allow higher levels of ultraviolet radiation to reach the earths surface, which is theorized to cause higher incidence of skin cancer in humans and reduced crop yields. Becaus

14、e of the phase-out of trichloroethane, the electric industry has been put in the situation of seeking substitute materials to meet its solvent needs. Trichloroethane had reached the status of a cleaning solvent that “just worked“ as confirmed over the many years that it was used. However, industry-w

15、ide specification or evaluation criteria were never written for this product and the many applications where it was used. This guide provides evaluation categories, test methods, and reasonable acceptance criteria that can be used by the electric industry to evaluate the numerous and diverse lot of

16、chemicals being proposed as replacements for trichloroethane for use as electrical cable and accessory cleaning solvents. The work of preparing this guide was carried out by Working Group B9W of the Accessories Subcommittee of the Insulated Conductors Committee of the IEEE Power Engineering Society.

17、 The original chair of this Working Group, Mr. Gene Weitz, was responsible for the development of this guide. Before the guide could be finalized, both Mr. Weitz and the vice chair, Mr. Peterson, resigned from the Working Group due to changes in their business focus. Unfortunately, the names of the

18、Working Group members were lost during that transition. The current chair and vice chair assisted with the development of this guide but are careful to note that much credit for pushing the guide through the rigorous development process belongs to Mr. Weitz and Mr. Peterson. v Copyright 2007 IEEE.

IEEE Guide for the Evaluation of Solvents Used for Cleaning Electrical Cables and Accessories 1. Scope This guide serves two primary purposes. The first is to outline many of the issue

32、s associated with using a solvent as an electric cable cleaner. The second is to provide a variety of tests that can be used for evaluating the performance of solvents intended for cleaning electric cables or cable accessories used by electric utilities. Tests for assessing the compatibility of a cl

33、eaning solvent with various cable and cable accessory components and tests for assessing cleaning effectiveness are included within this guide. Although many materials are used in cable systems, this guide covers only the basic cable and cable accessory components with a focus on electric power cabl

34、es. The guide may be applied to materials outside the scope of this document at the users discretion. The compatibility tests include suggested or target acceptance criteria to help assure that the solvent does not harm the component it is intended to clean. As this document is a guide, these values

35、 are not requirements. They are only provided as guidelines and are based either on industry standard requirements for materials or on the best judgment and experience of the working group members who prepared the document. They will be modified by the P1493 Working Group as additional data become a

36、vailable. The cleaning effectiveness tests are comparative tests with no specific performance requirements. Throughout this guide, the terms “solvent” and “cleaner” are both used to describe the chemical intended for use as a cable cleaner. 1 Copyright 2007 IEEE. All rights reserved. IEEE Std 1493-2

49、 Administration VOC volatile organic compound 4. General Most cleaning solvents proposed as replacements for the chlorinated fluorocarbon (CFC) solvents are very different from CFCs. The alternative solvents have flash points versus no flash point, dry very slowly versus extremely fast, may be conductive versus nonconductive, and may be incompatible with sensitive electrical polymeric components versus proven compatibility. In addition, the proposed materials are extremely diverse. Therefore, it is very important that
