CEN/TC 121/SC 5/WG 7 - Destructive testing

ISO 17641-2:2005 specifies the required specimens, the test piece dimensions and the procedures to be followed to carry out self-restraint hot cracking tests.
The following tests are described:
T-joint weld cracking test;
weld metal tensile test;
longitudinal bend test.
The tests are designed to provide information about the hot cracking sensitivity of weld metals. The tests are not suitable for the assessment of parent materials.
This International Standard applies primarily to fully austenitic stainless steels; nickel, nickel-base and nickel-copper weld metals. It can also be used for other weld metals.
ISO 17641-2:2005 describes only how to carry out the tests and report the results. It does not give any acceptance criteria.

IS0 9018:2003 specifies the sizes of test pieces and test specimens and the procedure for carrying out tensile tests in order to determine the tensile strength and the location of fracture of welded joints with transverse stressed fillet welds. It applies to metallic materials with welded cruciform and lapped joints on plates.
Information concerning evaluation of test results is not included in this International Standard.

ISO 14323:2006 covers destructive testing of welds.
ISO 14323:2006 specifies specimen dimensions and testing procedures for impact shear and cross-tension testing of spot and embossed projection welds in overlapping sheets, in any metallic material of thickness 0,5 mm to 4 mm.

ISO 17655:2003 specifies the determination of the delta ferrite content of welds, of surfacings with austenitic weld metal, welding being carried out on welding procedure tests and production coupon test plates using any fusion welding process that is suitable for austenitic materials, with or without filler metal including welds made on components.
It is intended that the ferrite number be used exclusively for stating the delta ferrite content of austenitic weld metal as determined by the method described in ISO 17655:2003.

This standard specifies the methods of specimen preparation, test procedures and their main objectives for the macroscopic and microscopic examination.

This European Standard specifies the sizes of test specimen and the procedures for carrying out fracture tests in order to obtain information about types, sizes and distribution of internal imperfections such as porosities, cracks, lacks of fusion, lacks of penetration and solid inclusions on the fracture surface.  This European Standard applies to metallic materials in all form of product with joints made by any fusion welding process with a thickness greater or equal to 2 mm.  This European Standard is used if required by the application standard or by the agreement between the contracting parties.

ISO 17653:2003 is applicable to spot welded test specimens with single sheet thicknesses ranging from 0,5 mm to 3,0 mm in steels. It may be used for non-ferrous materials in certain circumstances.
The aim of this test is to determine the influence of different steel types, welding parameters and other factors on the deformation characteristics of a spot weld. Using this test, it is possible to determine the weld diameter and the fracture type from fractured specimens. Additionally, the maximum torsion moment (torque) and the corresponding torsion angle can be determined.

ISO 17654:2003 specifies the pressure test method to be applied to resistance seam welded specimens of different types of material, e.g. uncoated and coated ferritic steels and uncoated austenitic steel sheet with single sheet thicknesses ranging from 0,3 mm to 3,2 mm.
The purpose of this pressure test is to determine the suitability of the material, welding equipment, welding parameters and of other factors on a tank, a vessel or a container for liquids or gases, which are manufactured by resistance seam welding.
