Abstract

The so-called 20 kips frame (MTS table-top machine), equipped with a 100 kN load cell with serial No. 850, was used in the period April-December 2010 to perform tensile tests on several steels. The main purpose of these tests was to establish benchmark values for the tensile properties of a number of steels, to be later compared to data measured from micro-sized tensile specimens in the framework of the Microsystems Project [1]. Three of the steels tested allow performing a verification of the force values provided by the load cell, namely: • Nimonic 75, commercialized by the Institute for Reference Materials and Measurements (IRMM – Geel, Belgium) with designation BCR-661, as Certified Reference Material for ambient tensile properties. • Two zinc-coated sheet steels coded A and C, provided by ASTM to NIST for participation in the E28 Proficiency Testing Program (PTP), “Mechanical Properties of Steel”. This Internal Report presents the results obtained at NIST from tensile tests performed on conventional samples in accordance with ISO and ASTM standards, and the comparisons with IRMM certified values (Nimonic 75) and with the results provided by other laboratories participating in the ASTM PTP (September 2010) and statistically evaluated by ASTM International [2].
