Re: [MW:4826] Radiographic film interpretation

Dear,

Shashank Vagal.

Refer ASME sec V article 2, T 282.2 page 14


T-282.2 Density Variation
(a) General. If the density of the radiograph anywhere
through the area of interest varies by more than minus
15% or plus 30% from the density through the body of
the hole IQI or adjacent to the designated wire of a wire
IQI, within the minimum/maximum allowable density
ranges specified in T-282.1, then an additional IQI shall be
used for each exceptional area or areas and the radiograph
retaken. When calculating the allowable variation in density,
the calculation may be rounded to the nearest 0.1
within the range specified in T-282.1.
(b) With Shims. When shims are used with hole-type
IQIs, the plus 30% density restriction of (a)
