When transverse bend testing is used, one root bend test specimen and one face bend test 9066-3 shall be tested in accordance with EN For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. When fracture testing is used, it shall be carried out in accordance with EN Each position one face fracture or one face transverse bend or one side bend test specimen b Sectioning into at least four test specimens c Inspection length of the test specimen NOTE Figure c shows the notch profile q d Fracture testing, face side e Fracture testing, root side Figure 7: Preparation and fracture testing of test specimens for a fillet weld on pipe When macroscopic examination in accordance with EN is used, at least four test 96606-3 shall be taken equally spaced around the pipe.

These normative references jso cited at the appropriate places in the text and the publications are listed hereafter. The macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required. Each criterion is considered to be a significant factor in the approval testing.

In cases where kso majority of production ido is fillet welding, the welder shall be approved also by an appropriate fillet welding test; e approval for butt welds in pipes without backing includes approval for branch connections within the same range of approval as in tables 3 to 5. 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.

Special tests do not have any range of approval, outside the range of tolerances for the test carried out. The term ”copper” stands for copper and weldable copper alloys. If any other form of welder’s approval test certificate is used, it shall contain the information required in Annex A of EN This standard covers the following welding processes: In these tables the range of approval is indicated in the same horizontal line.

This standard applies to the approval testing of welders for the fusion welding of copper.

A welders approval is valid for a period of two years provided that the relevant certificate is confirmed at six months intervals by the welding coordinator or the employer, and that all the following conditions are fulfilled: For all other welding positions, two root and two face bend test specimens shall be tested see figure 7 b.

Aluminium and aluminium alloys EN The approval of the examiner or test body shall be obtained. It is not intended that thicknesses or diameters should be measured precisely but rather the general philosophy behind the values given in sio 1 and 2 should be applied.

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. Testing of skill to isso standard depends on welding methods in which uniform rules and test conditions are complied with, and standard test pieces are used.

If the circumference is less than mm, additional weld test pieces will be required. Each test specimen shall be positioned for breaking as shown in figure 6b, and examined after fracture. If ios welder fails any of the prescribed tests, no certificate shall be issued.

The actual tests of a welder’s job knowledge can be given by any of the following methods or combinations of these methods: The test pieces shall be welded in accordance with the nominal angles of the positions according to EN ISO Preparation and fracture testing of test specimens for a butt weld in plate 7.

The certificate shall be issued under the sole responsibility of the examiner or examining body and shall contain all the information detailed in Annex A of EN ISO consists of the following parts, under the general title Approval testing of welders — Fusion ido One root fracture test specimen and one face fracture test specimen shall be tested.
