1.1.1 This Appendix contains details of acceptable design S-N curves and joint
classification. The details contained in this Appendix take due account of the

Classification of Offshore Installations, 4th edition, 1990.
1.1.2 All tubular joints are assigned Class T. Other types of joints are
assigned Class B, C, D, E, F, F2, G or W depending upon:
- geometric arrangements;
- direction of applied stress; and
- method of fabrication and inspection.
1.1.5 Other methods may be used after special consideration and agreement with
