Scope

This Standard specifies the metallographic-structure’s grade-level, inspection and
examination methods for internal combustion engines’ casting eutectic aluminum-
silicon alloy pistons AND aluminum-silicon-copper-magnesium (Al-Si-Cu-Mg) alloy
pistons.
This Standard is applicable to metallographic-structure inspection of internal
combustion engines’ casting eutectic aluminum-silicon alloy pistons AND Al-Si-Cu-Mg
alloy pistons, which are after heat treatment and of which the cylinder diameter is less
than or equal to 200mm.
