This technical report gives framework guidelines for collecting environmental data of insulating materials useful to engineers and designers of electrotechnical products for evaluating environmental impacts. It also provides a guideline for common format in environmental data reporting. This will enable producers to more easily evaluate the potential environmental impacts of those electrotechnical products using solid insulating materials. Moreover, it will allow a quick assessment of conformity to relevant electrotechnical productrelated environmental regulations.

This part of IEC 61212 gives requirements for industrial rigid round laminated rolled tubes for electrical purposes, based on different resins and different reinforcements. Applications and distinguishing properties are given in Table 1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. Safety warning: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner.

This International Standard describes a method of test for comparing the performance of insulating materials, when they are exposed intermittently to a liquid contaminant and then to an a.c. electric stress along their su rface. It should be realized that the test was developed to compare the resistance to tracking and erosion of materials belonging to one specific family, so that comparisons between results in different families may not be fully valid. The test apparatus uses a rotating wheel on which standard' ) rod- or tube-shaped specimens, fitted with electrodes at each end, are located around the periphery of the wheel. The wheel, mounted at a small angle to the horizontal, is rotated slowly so that the test specimens are repeatedly dipped in a specified salt-water solution (contaminant) and then withdrawn. After withdrawal, the solution is allowed to drain or drip from the surface of the test specimen for a short time before a specified voltage is applied. The voltage causes electrical discharges (tiny arcs, scintillations) across dry areas which develop on the su rface of the specimens. These discharges may cause surface degradation to progress; until flashover occurs, or the leakage current exceeds a specified value 2) . The time to flashover, or to exceed the specified leakage current, and observation of the nature and severity of degradation are the criteria used to compare materials. The test conditions are such that materials suitable for use out of doors normally fail within a few thousand hours. IEC 112 and IEC 587 (see annex B) describe tests of much shorter duration, on smaller samples, to assess the ability of materials to withstand electric stress when exposed to liquid contamination on one surface. These tests may rate materials differently from tests of longer duration. Salt-fog tests (not yet standardized by IEC) are also in use. Such tests permit comparison of materials in the form in which they will be used in service. The test results are then dependent both on the materials used and the design of the test specimens. Such tests may also evaluate materials differently.

These methods of test cover procedures for the determination of insulation resistance without discrimination between the volume and surface resistances involved. Because the test specimens are simply and easily prepared, these methods are particularly useful for rapidly determining values which will give a general indication of quality when great accuracy is not required.

Gives the requirements for industrial rigid laminated sheets for electrical purposes based on polyimide resins and different reinforcements. Applications and distinguishing properties are given. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. In this revision of the IEC 60893 series of specifications, new material types have been included, changes have been made to the property requirements of some existing types, a new method for testing permittivity and dissipation factor has been added, and all non-specification data for each type has been moved to a new Part 4 document - IEC 60893-4; Typical values.

Electrical insulation systems and materials may be tested using constant stress tests in which times to breakdown are measured for a number of test specimens, and progressive stress tests in which breakdown voltages may be measured. In either case, it will be found that a different result is obtained for each specimen and that, for given test conditions, the data obtained may be represented by a statistical distribution. This guide describes, with examples, statistical methods to analyze such data. The purpose of this guide is to define statistical methods to analyze times to breakdown and breakdown voltage data obtained from electrical testing of solid insulating materials, for purposes including characterization of the system, comparison with another insulator system, and prediction of the probability of breakdown at given times or voltages. Methods are given for analyzing complete data sets and also censored data sets in which not all the specimens broke down. The guide includes methods, with examples, for determining whether the data is a good fit to the distribution, graphical and computer-based techniques for estimating the most likely parameters of the distribution, computer-based techniques for estimating statistical confidence intervals, and techniques for comparing data sets and some case studies. The methods of analysis are fully described for the Weibull distribution. Some methods are also presented for the Gumbel and lognormal distributions. All the examples of computer-based techniques used in this guide may be downloaded from the following web site “http:// grouper.ieee.org/groups/930/IEEEGuide.xls.” Methods to ascertain the short time withstand voltage or operating voltage of an insulation system are not presented in this guide. Mathematical techniques contained in this guide may not apply directly to the estimation of equipment life.

This Technical Report gives information for the assessment of factors associated with the polymer recycling and/or reuse of typical insulating materials in electrotechnical equipment. It gives information and assistance to developers and design engineers for assessment in selecting polymers and polymer combinations, and is a contribution to the preservation of resources and the minimization of disposal costs at the end of a product life. The environmental compatibility of polymers must be assessed in the light of the function of the materials in the product and the total service life. An important aspect is the recovery of the material at the end of the product life. The value level of material recycling as recovery option can be improved by incorporation of suitability for dismantling into the design of the article and the choice of insulating materials which are generally used. This document will cover material recycling only as part of recovery.
