This guide describes the use of standard reference photographs depicting the appearance of previously unpainted hot-rolled carbon steel prior to and after abrasive blast cleaning. These photographs are intended to be used to supplement the written SSPC blast cleaning surface preparation specifications. As the written specifications are the primary means to determine conformance with blast cleaning requirements, the photographs shall not be used as a substitute for these specifications.
The standard consists of a series of 1:1 (actual size) color photographs which represent various conditions of unpainted steel surfaces prior to and after surface preparation by abrasive blast cleaning.
