QJ 1309A-2008 Classification of disperse porosity for ZL104 alloy castings
1 Scope
This standard specifies the classification of dispersed porosity for ZL104 aluminum alloy sand castings (hereinafter referred to as "castings") using X-ray radiography, and provides the corresponding X-ray radiography standard films.
This standard is applicable to the X-ray radiography assessment of ZL104 alloy castings with a wall thickness not exceeding 20mm. For castings with a wall thickness greater than 20mm but less than 50mm, it can be used as a reference.
This standard is not applicable to the classification of spongy porosity for ZL104 alloy castings.
