铝压铸件气孔标准
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。
