This guide describes the use of reference photographs depicting the appearance of both previously unpainted and previously painted and partially rusted hot-rolled carbon steel prior to and after abrasive blast cleaning. These photographs are intended to be used to supplement the written SSPC/NACE International blast cleaning surface preparation standards. The written standards are the primary means to determine conformance with blast cleaning requirements. The photographs shall not be used as a substitute for the written standards.
The reference photographs consist of a series of 1:1 (actual size) color photographs that represent various conditions of unpainted and painted steel surfaces prior to and after surface preparation by abrasive blast cleaning. The photographs were taken under controlled studio lighting designed to show the maximum detail possible.
