SPECIMEN JIG FOR TENSION TEST USING SMALL SIZED SPECIMEN

摘要

PURPOSE: A specimen jig for tension test is provided to achieve improved accuracy of alignment between load applying shaft and specimen, while preventing a small specimen from sliding during test. CONSTITUTION: A specimen jig comprises a main body(10) including one or more first bar insertion holes(11) for coupling with a coupling bar(51) so as to accomplish an alignment with a back plate(30), a specimen insertion portion(13) for insertion of a small specimen(12), a specimen fixing screw hole(15) for fixing the small specimen, and a tension tester fixing portion(21) for connecting the specimen jig body to a tension tester; a back plate(30) having one or more second bar insertion holes(31) for coupling with the coupling bar so as to accomplish an alignment with the main body, wherein second bar insertion holes are formed at the position same with the position of first bar insertion holes; the coupling bar fit to first and second bar insertion holes; and a screw(53) coupled to the specimen fixing screw hole formed at the main body.
