ISO 15607:2003 defines general rules for the specification and qualification of welding procedures for metallic materials.
It also refers to several other standards as regards detailed rules for specific applications. ISO 15607:2003 is applicable to manual, mechanized and automatic welding.

ISO 2553 defines the rules to be applied for symbolic representation of welded, brazed and soldered joints in metallic materials on technical drawings. This can include information about the geometry, manufacture, quality and testing of the welds. This International standard is a combined specification that recognizes that there are two different approaches in the global market to designate the arrow side and other side on drawings. It should be noted that: - Clauses, Tables and Figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on the dual reference line; - Clauses, Tables and Figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on the single reference line; - Clauses, Tables and Figures which do not have the suffix letter "A" or the suffix letter "B" are applicable to both systems.The symbols shown in this International Standard can be combined with other symbols used on technical drawings for example to show surface finish requirements.

ISO 2553:2013 defines the rules to be applied for symbolic representation of welded joints on technical drawings. This may include information about the geometry, manufacture, quality and testing of the welds. The principles of this standard may also be applied to soldered and brazed joints.
It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In ISO 2553:2013: sections, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line; sections, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line; sections, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems.
The symbols shown may be combined with other symbols used on technical drawings, for example to show surface finish requirements.
An alternative designation method is presented which may be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements.

ISO 17638:2003 specifies techniques for detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The techniques are suitable for most welding processes and joint configurations.

This European Standard outlines the general rules for industrial X- and gamma radiography for flaw detection purposes, using film techniques, applicable to the inspection of metallic materials.   The examination shall be carried out by competent personnel qualified and certified according to EN 473 where applicable.   It does not lay down acceptance criteria of the imperfections.

This European Standard specifies fundamental techniques of radiography with the object of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on generally recognized practice and fundamental theory of the subject.  This standard applies to the radiographic examination of fusion welded joints in metallic materials.  It applies to the joints of plates or pipes. Besides its conventional meaning, "pipe" as used in this standard should be understood to cover other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels. This standard compies with EN 444.  This standard does not specify acceptance levels of the indications.  If contracting parties apply lower test criteria, the quality achieved may be significantly lower than when this standard is stricly applied.

Applies to nuts with nominal thread diameters up to and including 39 mm, specific mechanical requirements, widths across flats as specified in ISO 272, nominal heights greater than or equal to half the nominal diameter of the internal thread, made of carbon steel or low alloy steel. Does not apply to nuts requiring special properties (such as weldability, corrosion resistance, etc.). Values apply when tests are made at room temperature.

EC - New Annex ZA

This European Standard defines the qualification test of welders for the fusion welding of steels.
It provides a set of technical rules for a systematic qualification test of the welder, and enables such qualifications to be uniformly accepted independently of the type of product, location and examiner/examining body.
When qualifying welders, the emphasis is placed on the welders ability to manually manipulate the electrode/ welding torch/ welding blowpipe and thereby producing a weld of acceptable quality.
The welding processes referred to in this European Standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automated welding processes (see EN 1418).

This European Standard covers the visual examination of fusion welds in metallic materials. The examination is normally performed on welds in the as-welded condition but exceptionnally, for example when required by an application standard or by agreement between the contracting parties, the examination may be carried out at other stages during the welding process.

This standard specifies the sizes of test specimen and the procedure for carrying out transverse tensile tests in order to determine the tensile strength and the location of fracture of a welded butt joint.   This standard applies to metallic materials in all forms of product with joints made by any fusion welding process.   Unless otherwise specified for specific points in this standard, the general principles of EN 10002-1 shall apply.

This European Standard specifies methods for the manual ultrasonic examination of fusion welded joints in metallic materials equal to and above 8 mm thick which exhibit low ultrasonic attenuation (especially that due to scatter). It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic.  Where specified and appropriate, techniques may also be used :  - on materials other than those stated ;  - on partial penetration welds ;  - with automated equipment  by agreement between the contracting parties.  Where material dependent ultrasonic values are specified in this standard they are based on steels having an ultrasonic sound velocity of 5920 ñ 50 m/s for longitudinal waves, and 3255 ñ 30 m/s for transverse waves. This is to be taken into account when examining materials with a different velocity.   The standard specifies four examination levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of examination levels A, B and C is given in annex A. The requirements of the fourth examination level, which is intended for special applications, are in accordance with the general requirements of this standard and as agreed between the contracting parties.  This standard, by agreement between the contracting parties, permits assessment of indications, for acceptance purposes, by either of the following methods :  1) Evaluation based primarily on length and echo  amplitude of the signal indication ;  2) Evaluation based on characterization and sizing of the indication by probe movement methods.

ISO 2560:2009 specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of non-alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.
