This standard establishes a method for specifying certain welding, brazing, and nondestructive examination information by means of symbols. Detailed information and examples are provided for the construction and interpretation of these symbols. This system provides a means of specifying welding or brazing operations as well as nondestructive examination, including the examination method, frequency, and extent. Safety and health issues and concerns are beyond the scope of this standard, and therefore are not fully addressed herein. The limitations included in specifications and codes are also beyond the scope of this standard.
