Tables for Tubular Qualifications in 2015 are in clause 9 however regardless, you should find a statement within the code that allows WPS's qualified to previous versions to be acceptable. So I would start there. However if you have to have 2015 compliant WPS's think about the below info.
Often errors in newly released codes that are addressed by errata sheets. Take a look at this and make sure your table you are viewing is not included.
http://www.aws.org/library/doclib/errata-D1.1-D1.1M-2015.pdf Below is the Text from the 2015 code about the reorginization of the Tubular requirements. Almost always there is an error in the tables in D1.1....Why ? Who knows.
The 2015 edition of the code has been reorganized. The tubular provisions, tables, and figures previously located throughout the code are now within Clause 9 entitled “Tubular Structures.” The reorganization required numerous reference changes and renumbering of the subclauses, tables, and figures. Many of the tables in Clause 4 contained provisions for Plate as well as Pipe or Tubing. The tables have been divided to only include Plate if contained in Clause 4 and Pipe or Tubing if contained in Clause 9. This separation of the information contained in the tables also resulted in many changes to the footnotes delineated in the tables.Hope t his helps you in what you need.
