ASTM B987/B987M-25

Annotation of standard text ASTM B987/B987M-25 :

This specification covers carbon fiber composite core/thermoset (CFCC/TS) matrix for use in reinforcing or supporting overhead electrical conductors. It provides requirements for CFCC/TS materials and manufacture, including tensile strength, glass transition temperature, and minimum bending diameter. This specification also applies to classes of CFCC/TS, test classifications and number of tests and retests, actual density of the CFCC/TS, minimum thickness of the galvanic protection barrier layer, joints, workmanship, finish and appearance, inspection, certification, and packaging and package material. The tests covered by this specification are: tensile test and glass transition temperature test, bending test, dye penetrant testing after bending test, tensile test after bending test, heat exposure test, and heat/stress test.
