Metals Testing
Metals testing sangat penting di seluruh dunia, karena logam adalah bahan utama untuk konstruksi dan akan terus berlanjut di masa depan. Tingginya persentase material baja dapat didaur ulang berkali-kali dan karena itu dianggap berkelanjutan. Pengetahuan tentang characteristic material data sangat penting bagi para desainer dan pengguna akhir. Data material diperoleh dari teknologi mekanis materials testing, di mana mesin penguji logam memuat material hingga gagal. Mesin uji dari ZwickRoell Group memastikan hasil tes yang dapat direproduksi dan dapat diandalkan. Hal ini didasarkan pada metode pengujian logam yang terstandardisasi secara internasional sesuai dengan ISO standards dan ASTM standards.

Metal Testing Methods
Pada umumnya, logam diuji menurut standar tertentu. Metal standards are important when it comes to consistency and reproducibility of results obtained from mechanical metals testing. They ensure that test methods are standardized and reproducible, so that the mechanical properties of these metals can be reliably evaluated. Hal ini sangat penting untuk jaminan kualitas, penelitian dan pengembangan, pemilihan material, dan tujuan perhitungan desain di banyak industri, termasuk otomotif, aerospaces, konstruksi, dan banyak lagi.
Standar yang paling penting untuk pengujian logam mekanis meliputi:
- ASTM E8 / ISO 6892-1: standar ini menetapkan metode pengujian untuk tensile strength, yield strength, strain dan reduksi area cross-sectional dari metals. Mereka mendefinisikan prosedur untuk tensile tests pada spesimen logam standar pada suhu kamar dan memungkinkan penentuan sifat mekanik yang penting. Standar ASTM E21 / ISO 6892-2 menentukan uji tarik pada logam pada suhu tinggi.
- ASTM E23 / ISO 148-1: standar ini mencakup Charpy impact test method untuk metals. Tes ini mengukur kekuatan dan ketahanan suatu bahan ketika mengalami beban benturan.
- ASTM E399 / ISO 12135: standar ini menetapkan metode untuk penentuan crack initiation dan crack growth resistance properties dari metals.
- Hardness tests pada logam dijelaskan dalam standar ISO 6508 / ASTM E18 (Rockwell), ISO 6507 / ASTM E384 (Vickers), ASTM E92 (Vickers & Knoop) dan ISO 6506, ASTM E10 (Brinell).
