Table 4.6 is used only if notch toughness (CVN testing) is required. You make no mention of CVN, thus you do not have to use Table 4.6. Table 4.5 and clause 5 with regards to PWHT is sufficient.
My recommendation is to subject the test assembly to the PWHT describes in Clause 5, then follow Clause 5 for all production welds with regards to temperature and hold time, etc.
