Determination of ash for high pure graphite product
This test method provides a practical determination for the percentage of moisture in a graphite sample. This standard does not purport to address all of the safety problems, 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.
Test Method for Moisture in a Graphite Sample
This guideline covers the following areas for reporting friction and wear test results of manufactured carbon and graphite bearing and seal materials: Description of test device and techniques (Table 1). Description of carbon and graphite material test specimen (Table 2). Description of mating member test specimen (Table 3). Report of friction and wear test results (Table 4). Many types of equipment and techniques will yield consistent data characterizing the friction and wear of carbon and graphite materials. However, the ranking of the materials by the various test methods used is not necessarily the same. This guideline is an initial effort to promote more complete description of the test methods, whatever they may be. It is the eventual intent to identify one or more specific standard test methods when sufficient information becomes available.
Guide for Reporting Friction and Wear Test Results of Manufactured Carbon and Graphite Bearing and Seal Materials
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. 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.

The results obtained by these test methods should serve as a guide in, but not as the sole basis for, the selection of a chemical-resistant carbon brick for a particular application. No attempt has been made to incorporate into these test methods all the factors that may affect the performance of carbon brick when subjected to various actual service conditions.1.1 These test methods are intended for use as short-term tests for evaluating the physical properties of carbon brick at various temperatures in immersion service. These test methods provide a means of determining the following changes in the carbon brick specimen and the test media: 1.1.1 Weight, appearance and compressive strength of the carbon brick specimen. 1.1.2 Appearance of the test media before, during and after testing of the carbon brick specimen. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values stated in parentheses are for information only. 1.3 This standard does not purport to address all of the safety problems, 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.

Sonic velocity measurements are useful for comparing materials. A value for Youngrsquo;modulus can be obtained for many applications, which will generally be within 10 % of the value obtained by other methods, such as in Test Method C 747.1.1 This test method covers a procedure for measuring the sonic velocity in manufactured carbon and graphite materials having a grain size less than 0.80 mm (1/32 in.). The sonic velocity can be used to obtain an approximate value for Young''s modulus.1.2 The values stated in SI units are to be regarded as the standard.1.3 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.
Standard Test Method for Sonic Velocity in Manufactured Carbon and Graphite Materials for Use in Obtaining an Approximate Young''s Modulus
A Rockwell L scale hardness number is a number derived from the net increase in depth of impression as the load on a 6.3500- ± 0.0025-mm (0.2500- ± 0.0001-in.) diameter steel-ball indenter is increased from a fixed 10-kg minor load to a 60-kg major load and then returned to the minor load. A Rockwell hardness number is directly related to the indentation hardness of a material; the higher the Rockwell L scale reading, the harder the material. The test is useful in the evaluation and the manufacturing control of carbon and graphite materials. 1.1 This test method covers Rockwell L scale hardness testing of graphite materials with grain size less than 0.8 m (0.032 in.) and a hardness range between 0 and 120. 1.2 Test Methods E 18 shall be followed except where otherwise indicated.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 1.4 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.
