Density

为ASME第五节用户射线照相密度变化计算器。

A radiography density variation calculator for ASME Section V users. The code allows the density in the area of interest to be no more than minus 15% or plus 30% of the density that you measure through the hole type IQI or next to the essential wire on wire type IQIs.

The exception to this is when shims are used under hole style IQIs where the plus 30% may be exceeded.
