4.2 Choice of quality level
For me choico of the quality level, the following factors, among o(hers, shall be taken into account:
mechanical loading (static, dynamic):
environment (media, temperature):
material properties (ductile, brittle);
manutacturing conditions (workshop, construction site, welding in constrained con&tion); operating conditions;
potential danger in the event of failure.
5 Requirements for welded joints
The requirements for the above mentioned quality levels (B. C and D) are listed as follows:
Heated tool butt welds: Table 3;
Heated tool socket welds: Table 4;
Electrofusion welds: Table 5;
Hot gas welds: Table 6:
Extrusion welds: Table 7;
Solvent welds in pipes: Table 8.
Drfferent types of imperfection occurring simultaneously at any cross-section of the joint may need special consideration and advice should be sought from the product manufacture
Any two adjacent imperfections separated by a distance smaller man the major dimension of the smaller imperfection shall be considered as a single imperfection.
In certain circumstances, it is necessary to machine the completed weld. In this case, the weld shall be examined both before and after machining.
