Tensile Test for Metallic Materials INSTRUCTIONS TO PARTICIPATING LABORATORIES

To ensure that results from this program can be analyzed properly, participants are asked to adhere carefully to the following instructions. 1. SAMPLE The participating laboratory will obtain two round bars of metallic materials. These are numbered A and B for preparing standard 12.5mm round tensile test specimens. The capacity of testing machine had better over 150 kN. On receipt, unpack the artifacts and inspect them for any defects. Please contact with your accreditation body if there is damaged. 2. TESTS TO BE PERFORMED Sample Information: The two samples are Φ20mm × 250mm blank. Laboratory must machine tensile round specimen from the center of each blank. The standard round specimen has a 50mm gage length and 12.5mm in diameter of reduced section. Please refer to the part of Standard Specimen in ASTM E8M-04 FIG. 8. Testing Period: Test should be finished within one week after receiving the samples. Test Method: The method of tensile test at ambient temperature is according to ASTM E8M-04. In testing procedure, the preparation of test pieces and the speed of the testing shall also conform to ASTM E8M-04 requirements. The following mechanical properties of results must be obtained for each specimen
