ASTM C 565 Standard Test Methods for Tension Testing of Carbon and Graphite Mechanical Materials
ASTM C 565 covers the apparatus, specimen, and procedures for the tension testing of carbon and graphite mechanical materials with a grain size smaller
than 0.79 mm.
Significance and Use
ASTM C 565 may be used for quality control testing of established grades of carbon and graphite materials, in the development of new grades, and for other
purposes where relative strength levels are the primary quantities of interest.
This test method may be applicable only if the ratio of specimen diameter to grain size, or flaw size, is greater than 5.
ASTM C 565 does not substitute for that described in Test Method C749, but are useful where less sophisticated data and less expensive techniques are sufficient.
Carbon and graphite materials exhibit significant physical property differences within parent materials.
Exact sampling patterns and grain orientations must be specified in order to make meaningful tensile strength comparisons.
*** Before conducting this test standard , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
***PARSROS offers several types of grips and fixtures which will enable you to perform a variety of tests
that are accurate and repeatable.
