When transverse bend testing is used, it shall be carried out in accordance with EN The following conditions shall apply: The format of this Annex A of EN An approval test made on wrought material groups gives approval for cast material and a mixture of cast and wrought material in the same material group see 5.

The actual questions used should be drawn up by the individual country, but should include questions on areas covered in clause A. The examiner or examining body can stop uso test if the welding conditions are not correct or if it appears that the welder does not have the technical competence to comply to the requirements of this standard, e.
When welding parent lso from two different groups which do not give approval to each other according to table 4 see 6. A Reference number ISO However, some countries can require that the welder undergoes a test of job knowledge. For explanation of abbreviations used in the designation examples, see clause 4. A test is listed for each of the ranges of plate thickness and pipe wall thickness or pipe diameter as specified in tables 1 96063- 2.

If it is established that failure is attributed to the welder’s lack of skill, the welder shall be regarded as incapable of complying with the requirements of this standard without further training before re-testing.
In addition to radiography, two bend tests, one face, one root see EN or two fracture tests, one face, one root see EN shall always be applied to butt welds. For one root fracture or one root transverse bend or one side bend test specimen Position 2: This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating to welders’ competence in the various fields of application.

When fracture testing is used, it shall be carried out in accordance with EN The specimen preparation, types of notch profiles and methods of fracture shall be in accordance with EN The ability of the welder to follow verbal or written instructions and testing of his skill are important factors in ensuring the quality of the welded product.
These normative references are cited at the appropriate places in the text and the publications are listed hereafter. In these tables the range of approval is indicated in the same horizontal line.

Draft International Standards adopted by the Technical Committees are circulated to member bodies for voting. Dimensions in millimetres Figure 1: This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Augustand conflicting national standards shall be withdrawn at the latest by August Special tests do not have any range of approval, outside the range of tolerances for the test carried out.
In general, a welder’s approval test shall involve depositing weld metal having a chemical composition compatible with any copper in the parent metal group s. This annex outlines the job knowledge that a welder should have to ensure that procedures are followed and common practices are complied with.
If the job knowledge test is carried out, it should be recorded on the welder’s certificate. The test piece can be sectioned by mechanical means discarding the first and the last 25 mm of the test piece at the end of the plates figures 5 and 6.
It is not intended that thicknesses or diameters should be measured precisely but rather the general philosophy behind the values given in tables 1 and 2 should be applied. One root fracture test specimen and one face fracture test specimen shall be tested. Titanium and titanium alloys — Part 6: International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
Macroscopic tests shall be carried out in accordance with EN When required, visual examination can be supplemented by penetrant see EN or other test methods see table 6.
The number of fracture or transverse bend test specimens depends on the welding position. A change of process requires a new approval test.
Aluminium and aluminium alloys EN Welding procedure specification for arc welding EN Non destructive testing — Penetrant testing — Part 1: The range of approval for each type of test is given in the relevant sub-clauses and tables. The job knowledge indicated in this annex is only pitched at the most basic level.
When radiographic testing is used, the inspection length of the weld see figure 7 a and 7 b in the test piece shall be radiographed in the as-welded condition in accordance with EN ios class B technique. Reference should also be made to the corresponding acceptance criteria for non-destructive examination.
The type of shielding gas shall not be incorporated in the designation but shall be included in the welder’s approval test certificate see Annex A of EN For any copper alloy not covered by any of the copper groups the welder shall carry out an approval test, which only approves for that copper. A full explanation of these imperfections is given in EN When macroscopic examination is used, at least four test specimens shall be taken equally spaced in the inspection length.
If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN Dimensions of test piece for a fillet weld on pipe 7.
