ISO 5178-2019 pdf free.Destructive tests on welds in metallicmaterials — Longitudinal tensile teston weld metal in fusion welded joints.
This document specifies the sizes of test specimens and the test procedure for carrying out longitudinaltensile tests on cylindrical test specimens in order to determine the mechanical properties of weldmetal in a fusion welded joint.
This document applies to metallic materials in all forms of product with joints made by any fusionwelding process， having joint sizes that are sufficient to obtain cylindrical test specimens withdimensions in accordance with ISO 6892-1.
Unless specified otherwise for specific points in this document, the general principles ofIS06892-1 apply.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references,only the edition cited applies.Forundated references, the latest edition of the referenced document (including any amendments) applies.
No terms and definitions are listed in this document.
The test specimen shall be taken longitudinally from the welded joint of the manufactured product orfrom the test piece.After machining, the parallel length of the test specimen shall consist only of weldmetal (see Figures 1 and 2).
To enable correct positioning of the test specimen in the joint, the joint cross-section at both ends of thetest specimen can be macroetched.
Each test piece shall be marked in order to identify its exact location in the manufactured product or inthe joint from which it has been removed.
Each test specimen shall be marked in order to identify its exact location in the test piece from which ithas been taken.
When removed from the test piece, each test specimen shall be marked.
No heat treatment shall be applied to the welded joint or to the test specimen unless it is specified orpermitted by the relevant application standard dealing with the welded joint to be tested. Details of anyheat treatment shall be recorded in the test report. If natural ageing of aluminium alloys takes place,the time between welding and testing shall be recorded.ISO 5178 pdf download.
