EN ISO 5817 provides quality levels of imperfections in fusion-welded joints in all types of steel, nickel, titanium and their alloys.

The purpose of EN ISO 5817 is to define dimensions of typical imperfections which might be expected in normal fabrication. It may be used within a quality system to produce welded joints. It provides three sets of dimensional values from which a selection can be made for a particular application.

Three quality levels are given to permit application to a wide range of welded fabrication. For the application of this standard several types of loads are considered, e.g. static load, thermal load, corrosion load, pressure load.

The choice of quality level for any application should take account of design considerations, subsequent processing, mode of stressing, service conditions and consequences of failure. Economic factors are also important and should include not only the cost of welding but also of inspection, testing and repair.

EN ISO 5817 does not address the methods used for the detection of imperfections. EN ISO 5817 is directly applicable to visual testing of welds and does not include details of recommended methods of detection or sizing by non-destructive means.

The international standard has been approved in Europe as EN ISO 5817:2014 without any changes and it supersedes EN ISO 5817:2007.
