7.2. SPECIFIC QUANTITATIVE REQUIREMENTS FOR CERTAIN PRESSURE EQUIPMENT
Joint coefficients
For welded joints, the joint coefficient must not exceed the following values:
for equipment subject to destructive and non-destructive tests which confirm that the whole series of joints show no significant defects: 1,
for equipment subject to random non-destructive testing: 0.85,
for equipment not subject to non-destructive testing other than visual inspection: 0.7.
If necessary, the type of stress and the mechanical and technological properties of the joint must also be taken into account.
