(b) The applicant must determine a special factor of safety using quality controls and specifications that account for each: (1) type of application; (2) inspection method; (3) structural test requirement; (4) sampling percentage; and (5) process and material control. (c) The applicant must multiply the highest pertinent special factor of safety in the design for each part of the structure by each limit load and ultimate load, or ultimate load only, if there is no corresponding limit load, such as occurs with emergency condition loading.
