Categories:: Information management | Standardization. General rules | Measurement and Science | Testing | Engineering | Manufacturing engineering | Welding, brazing and soldering | Welding. Processes | Welding. Equipment | Welded joints and welds

Scope

This International Standard specifies the requirements for hardness testing of transverse sections of narrow laser and electron beam welded joints in metallic materials. It covers Vickers and Knoop hardness tests in accordance with ISO 6507-1 and ISO 4545, respectively, with test forces of 0,098 N to just under 98 N (HV 0,01 to just under HV 10) for the Vickers hardness test and test forces up to and including 9,8 N (just under HK 1) for the Knoop hardness test.

This International Standard is applicable to welds made with or without filler wire. It may not be applicable to the testing of wider hybrid laser/arc welds.

International Standards for hardness testing of welds without a narrow profile are ISO 9015-1 and ISO 9015-2.

Purpose

One world - one standard. Adoption of ISO document as an EN-ISO-document based on Dec 03/2020 of CEN/TC 121 on 2020-03- 03.
