BS EN ISO 9606-3:1999

A change of process requires a new approval test. The practical test and the examination of job knowledge see Annex A shall be designated by ”Accepted” or ”Not tested”. ISO consists of the following parts, under the general title Approval testing of welders — Fusion welding: Prior to mechanical testing, backing strips, where sio, shall be removed.

All isp test conditions shall be recorded on the certificate. The work of preparing International Standards is normally carried out through ISO technical committees.

When the filler 96066-3 is dissimilar to the parent metal group, an approval for that combination of parent metal group and filler metal is needed, except when permitted by table 4. If the circumference is less than mm, additional weld test pieces will be required. When macroscopic examination is used, at least four test specimens shall be taken equally spaced in the inspection length. However, some countries can require that the welder undergoes a test of job knowledge.

An interruption for a period no longer than six months is permitted; b There is no specific reason to question the welder’s skill and knowledge.

A Reference number ISO One root fracture test specimen and one face fracture test specimen shall be tested. It does not cover fully mechanized and automatic processes see 5. The macroscopic specimen shall be prepared and etched on one side to clearly reveal the weld see ENpolishing is not required.

For one root fracture or one root transverse bend or one side bend test specimen Position 2: When required, visual examination can be supplemented by penetrant see EN or other test methods see table 6.

Aluminium and aluminium alloys 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: In general, a welder’s approval test shall involve depositing 960-63 metal having a chemical composition compatible with any copper in the parent metal group s.

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.

Throughout the text of this standard, read ” In these tables the range of approval is indicated in the same horizontal line.

Preparation and fracture testing of test specimens for a fillet weld on plate 7. For undated references the latest edition of the publication referred to applies. Each member body interested in 960-3 subject for which a technical committee has been established has the right to be represented on that committee.

Titanium and titanium alloys — Part 6: When transverse bend testing is used, one root bend test specimen and one face bend test specimen shall be tested in accordance 966-3 EN Each change of the essential variables for the approval testing beyond the permitted ranges requires a new test and a new approval certificate.

lso When transverse bend testing is used, it shall be carried out in accordance with EN Macroscopic tests shall be carried out in accordance with EN 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 specimens shall be taken equally spaced around the pipe.

A full explanation of these imperfections is given in EN For welding position PA or PC, one root and one face bend test specimen shall be tested see figure 7 a.

Welding procedure specification for arc welding EN Non destructive testing — Penetrant testing — Part 1: Owing to different training programmes in ieo countries, it is only proposed to standardize general objectives or categories of job knowledge.

If any of these conditions are not fulfilled, the approval shall be revoked.

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 using class B technique.
