Rationale

F2311-08, Standard Guide for Classification of Therapeutic Skin Substitutes, which has expired, included (1) definitions related to skin wounds, (2) a classification of products according to their cellular and tissue components, and (3) a classification of products according to their clinical uses. F3163-16, Standard Guide for Classification of Cellular and/or Tissue-Based Products (CTPs) for Skin Wounds incorporated most of the skin wound definitions and the classification by components of F2311. Thus, the publication of F3163 made these parts of F2311 redundant. This revision of F2311 excludes the overlap and retains its original purpose to define and classify the physiological and clinical functions of TEMPs used for skin replacement procedures.
