In the top x-ray of the die-cast anode dark circular shadows depicting sub-surface shrinkage can be ashm around the area of the pouring cup, i.
ASTM E – 15 Standard Reference Radiographs for Ductile Iron Castings
As the voice of the U. However, the size and frequency of these flaws are sufficiently small so their existence does not immediately require the need for the casting to be scrapped.

Therefore, the adjunct reference radiographs remain valid for use with this standard regardless of the date of production or the revision level of the text standard.
SI xstm are shown for information only. The x-ray image of the die-cast anode above shows a serious casting aw visible as a dark shadow in the connection area and is a real-life sample con rming the di culties encountered with this design. It should be noted that the type of defect awtm on the x-ray and its position in the casting will further influence the design life. Need more than one copy?
