What is ISO 9015-1 - arc welded joints hardness testing about?
The ISO 9015 series is an International Standard that discusses destructive tests on welds in metallic materials. ISO 9015 provides the requirements of hardness testing for welded joints.
ISO 9015-1 is the first part of the ISO 9015 series, and specifies hardness tests on transverse sections of arc welded joints of metallic materials. ISO 9015-1 covers Vickers hardness tests in accordance with ISO 6507-1 , normally with test loads of 49,03 N or 98,07 N (HV 5 or HV 10).
The principles may be applied to Brinell hardness testing (with appropriate testing loads of HB 2,5/15,625 or HB 1/2,5) in accordance with ISO 6506-1 and micro hardness testing in accordance with ISO 6507-1 and ISO 9015-2 .
Testing should be carried out to ensure that the highest and the lowest level of hardness of both parent metal and weld metal is determined.
Note: ISO 9015-1 does not apply to test welds in austenitic stainless steel.
