ASTM C749-13<\/h3>\n

Historical Standard: Standard Test Method for Tensile Stress-Strain of Carbon and Graphite<\/h4>\n
\n

ASTM C749<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1 This test method covers the testing of carbon and graphite in tension to obtain the tensile stress-strain behavior, to failure, from which the ultimate strength, the strain to failure, and the elastic moduli may be calculated as may be required for engineering applications. Table 2<\/span> lists suggested sizes of specimens that can be used in the tests.<\/p>\n

\n TABLE 2 Sample Sizes Used in Round-Robin Tests (Suggested Specimen Size)A<\/i><\/sup><\/b>\n <\/div>\n
\n A<\/i><\/sup>\u2009Based on Research Report RR:C05-1000 (see Section 11<\/span>).\n <\/div>\n

\n C<\/i><\/sup>\u2009Gas-bearings.\n <\/div>\n<\/p><\/div>\n
\n Note 1<\/span>\u2014The results of about 400 tests, on file at ASTM as a research report, show the ranges of materials that have been tested, the ranges of specimen configurations, and the agreement between the testers. See Section 11<\/span>.<\/span>\n <\/div>\n
\n Note 2<\/span>\u2014For safety considerations, it is recommended that the chains be surrounded by suitable members so that at failure all parts of the load train behave predictably and do not constitute a hazard for the operator.<\/span>\n <\/div>\n<\/p><\/div>\n

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Conversions are not provided in the tables and figures.<\/p>\n<\/p><\/div>\n

\n

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.<\/i><\/p>\n<\/p><\/div>\n
