ISO 20482 Bahan logam – Sheet Erichsen cupping test machine/tester
The cupping testing machine is used to test extend and stretch capacity of metal thin plate and band. Ini adalah satu-satunya instrumen yang menguji deformasi plastis logam. Juga dapat digunakan untuk menguji karakter anisotropik logam non-ferrous jika menambahkan cetakan impact cup. Mesin ini mengadopsi instrumen ukuran raster presisi tinggi untuk menguji nilai Erichsen sehingga memiliki presisi pengujian yang tinggi. Ini mengadopsi onload mesin kontrol listrik dan sensor jari-jari LCD sehingga meningkatkan presisi pengujian gaya uji utama dan akurasi pengendalian pemecahan sampel..
Cupping Test to Erichsen (ISO 20482) and Olsen (ASTM E643)
ISO 20482 standard describes the cupping test to Erichsen and is used to determine the ductility of metal sheets and strips. The test is also standardized in ASTM E643 as cupping test to Olsen. An additional description can be found in the Japanese standard JIS Z-224.
The forming process used for this test essentially records the stretching capacity of the metal material, directly comparable with a stretch-forming and bulge removal process. The edge zones (borders) are held, and therefore are not affected, or only slightly affected, by forming. The specimen is pulled until a crack occurs that runs the full thickness of the specimen, and is just wide enough to allow light to pass through part of its length.
