If the drop in back re? Additionally, prior approval must be obtained if the weld repaired surface exceeds 1. When this condition is observed it shall be investigated additionally by use of multiple back re? Three levels of acceptance standards are provided. A is for steel plate and A is for alloy clad steel plate. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Minor sensitivity adjustments may be made to accommodate for surface roughness. All discontinuities causing complete loss of reflection shall be a78.
