Metallic materials - Sheet and strip - Determination of biaxial stress-strain curve by means of bulge test with optical measuring systems (ISO 16808:2014); German version EN ISO 16808:2014
Metallische Werkstoffe - Blech und Band - Bestimmung der biaxialen Spannung/Dehnung-Kurve durch einen hydraulischen Tiefungsversuch mit optischen Messsystemen (ISO 16808:2014); Deutsche Fassung EN ISO 16808:2014
Overview
This International Standard specifies a method for determination of the biaxial stress-strain curve of metallic sheets having a thickness below 3 mm in pure stretch forming without significant friction influence. In comparison with tensile test results, higher strain values can be achieved. This document (EN ISO 16808:2014) has been prepared by Technical Committee ISO/TC 164 "Mechanical testing of metals", Subcommittee SC 1 "Uniaxial testing" (secretariat: AFNOR, France), in collaboration with Technical Committee ECISS/TC 101 "Test methods for steel (other than chemical analysis)" (secretariat: AFNOR, France) in accordance with the Vienna Agreement. Regarding the German collaboration, Working Committee NA 062-01-42 AA "Zug- und Duktilitätsprüfung für Metalle" ("Tensile and ductility testing of metals") at the Standards Committee Materials Testing (NMP) is responsible.
