Interpretations do not introduce new requirements. The most common applications for Code Cases are as follows: (-a) to permit early implementation of an approved Code revision based on an urgent need (-b) to permit use of a new material for Code construction (-c) to gain experience with new materials or alternative requirements prior to incorporation directly into the ð17Þ Code (3) Code Interpretations (-a) Code Interpretations provide clarification of the meaning of existing requirements in the Code and are pre- sented in Inquiry and Reply format. However, users are cautioned that not all regulators, j urisdictions, or Owners automatically accept Code Cases. When used, Code Cases prescribe mandatory requirements in the same sense as the text of the Code. Code Cases are writ- ten as a Question and Reply, and are usually intended to be incorporated into the Code at a later date. Code Cases represent alternatives or additions to existing Code requirements. Code revisions are considered to accommodate technological developments, to address admin- istrative requirements, to incorporate Code Cases, or to clarify Code intent. Technical inquiries can include requests for revisions or additions to the Code requirements, requests for Code Cases, or requests for Code Interpretations, as described below: (1 ) Code Revisions.
