PREFACE
Ihis Standard was prepared by Standards Australia Committee MT-006 MechanicalTesting of Metals to supersede AS13911991 Methodsfor tensile resting of metals heCommittee decided to change the title of the Standard to indicate the testing temperature at the time of test The title was changed to Metallic materiais-Tensile testing at ambienttemperature.
Ihe objective of this edition is to align more closely with ISO 6892:1998 Metallicmaterials-Tensile testing atambient temperature.
During the preparation of this Standard cognisance was taken of the following Standards:
1545 AS Methods for the calibration and grading of extensometersISO377 Steel and steel productsLocation and preparation of samples and test piecesfor mechanical testing3785 SteelDesignation of test piece axes Metallic materials-Tensile testing at ambient temperature156 6892 Metallic materials-Calibration of extensometers used in uniaxial testing
This Standard is one of a series of Standards covering the range of tensile testing methodsIhe seties prises the following:
AS1391 Metaillic materialsTensile testing at ambient temperature (this Standard)1545 Methods for the calibration and grading of extensometers Methods for the determination of transverse tensile properties of round steel1855 pipes2291 Methods for tensile testing of metals at elevated temperatures2403 Method for the measurement of the plastic strain ‘r’ of shcct and strip metals2346 Methods for the determination of uniform elongation in sheet and strip metals
The terms *normative’and “informative’ have been used in this Standard to define theapplication of the appendix to which they apply.Anormativeappendix is an integral part of a Standard whereas an *informative’ appendix is only for information and guidance.
