    Abstract - (Show below) - (Hide below)

    CONTAINED IN VOL. 02.02, 2014 Specifies magnesium-alloy investment castings designated.

    Scope - (Show below) - (Hide below)

    1.1This specification covers magnesium-alloy investment castings designated as shown in Table 1.

    TABLE 1 Chemical Composition LimitsA
    Note 1—Analysis shall regularly be made for the elements specifically mentioned in this table. If, however, the presence of other elements is suspected or indicated in amounts greater than the specified limits, further analysis shall be made to determine that these elements are not present in excess of the specified limits.
    Note 2—The following applied to all specified limits in this table: For purposes of acceptance and rejection, an observed value or a calculated value obtained from analysis should be rounded off to the nearest unit in the last right-hand place of figures used in expressing the specified limit.
