1. SCOPE
适用范围:
This specification applies for aluminum-alloy die casting porosity definition. It based on original spec of ASTM E505, but not for substitute of original spec, it only provide more comprehensive interpretion, so as to use with original spec. The requirement would override the original spec when conflict.
本规范涵盖了所有铝合金压铸砂孔的要求。本规范参照美国材料实验协会标准ASTM E505的原始规范,但不取代原规范,仅提供更全面的说明,所以原规范必须使用。当本规范和原
规范的内容矛盾时,本规范要求取代原规范内容。

备注:
Unless special explanation, void with size of ≦0.5mm will not be considered as porosity, and this apply to inside and on the surface
porosity of aluminum-alloy die casting!
如果没有特别说明,0.50mm及以下的气孔不作为砂孔的评估控制范围内,此要求适用于铝合金压铸件的内部和加工表面!
