内容简介

Core sampling is an acceptable way of obtaining a test specimen without destroying the usefulness of the electrode.4.1.1 Test specimens obtained by this practice can be used by producers and users of graphite electrodes for the purpose of conducting the tests in Note 1 to obtain comparative physical properties.This practice may not provide a test specimen of the appropriate size (with respect to particle size/sample dimension ratios) to allow the determination of absolute property values.1.1 This practice was developed for electric-arc furnace graphite electrodes, and covers a procedure and equipment for obtaining core samples from electrodes in a manner that does not destroy the electrode nor prevent its subsequent use as originally intended. However, the minimum electrode diameter, for which extraction of a core sample using this practice does not influence subsequent use, is influenced by the particular application and must be determined by the user. graphite electrodes for use in electric arc furnaces are usually solid cylinders of graphite with threaded sockets machined in each end. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 1-The following ASTM standards are noted as sources of useful information: Test Methods C559, C611, C651, C747, C1025, and C1039.
