Are the inspection requirements of TSG D0001-2009 consistent with those of GB20801?

Article 84 of TSG D0001-2009 states that \"the selection of welded joints to be inspected shall include those welded by each welder, and the number of fixed-welded joints shall be no less than 40% of the total number to be inspected.\" GB20801.5 divides inspection levels into 5 categories, while the proportion of non-destructive testing is set at 100%, 20%, 10%, and 0% respectively – how can these be made consistent?
