Density

為ASME第五節用戶射線照相密度變化計算器。

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.
