A batch of welds is a quantity of welds, welded by one welder or welding operator, in accordance with a specific welding procedure specification

8.1.3 Imperfections revealed by sample inspection

When sample inspection reveals imperfections in one weld which are not acceptable to this European Standard, the following shall apply for each defective weld:

8.2.1 Extent of testing

The type of NDT required and its extent shall be determined in accordance with Table 8.2-1, taking into account the category the piping is classified to and also wall thicknesses and material grouping

For piping where creep or fatigue is the controlling factor in design:

a) additional extent of NDT is required by Table 8.2-1, Note f, critical areas shall be included in the test; b) the quality level given in Table 8.4.2-1 for these service conditions shall be met

For piping of pipe category 0 and piping operating at or below 0,5 bar the amount of NDT shall be suitable to assure weld quality For volumetric testing a minimum amount of 2% is recommended When pneumatic testing

is used, the extent of testing according to Table 9.3.3-1 applies When agreed in the purchase order, for piping of category I made of material of material group 1.1, 1.2 and 8.1 an amount of 2% volumetric testing may be sufficient, if satisfactory experience exists
