WPS Qualification AWS D1.1 2020, Box to Box WPS Sample

[naquib]

Regarding of the topic above,
I want to make a WPS using Box to Box sample. However, there some confusion regarding the spec :-

1- Table 10.11 note c mention for the pipe diameter qualification, does it apply for box sample?

2- for WQT, table 10.12, it shown pipe only for fillet weld. does box sample is not applicable for wqt?

3- For WPS qualification using box, it mention 1 in each position to be used. does that mean if i want to make a wps for 1F i cannot use 5F sample? eventhough it mention in table 10.8, 5f position qualifies for all postion.
