1.1 This specification covers magnesium alloy permanent mold casting alloys designated as shown in Table 1.
TABLE 1 Chemical Composition LimitsA Note 1???
Analysis shall regularly be made only 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 applies to all specified limits in this table: For purposes of acceptance and rejection, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit. | Alloy NumberB | Composition, % |
