29、 in August 2013.AAnalysis shall ordinarily be made only for the elements mentioned in this table. If, however, the presence of other elements is suspected, or indicated in the course ofroutine analysis, further analysis shall be made to determine that the total of these other elements are not presen
30、t in excess of specified limits.BFor purposes of acceptance and rejection, the observed value or calculated value obtained from analysis should be rounded off to the nearest unit in the last right-handplace of figures, used in expressing the specified limit, in accordance with the rounding procedure
31、 prescribed in Section 3 of Practice E29.CLimits are in percent maximum unless shown otherwise.DAlloys 360.0, 380.0, 413.0, C443.0 and 518.0 are suitable for the production of die casting by either the hot-chamber or the cold-chamber process. Die castings of alloysA360.0, A380.0, 383.0, 384.0 and A4
32、13.0 may be made only in cold-chamber machines. ASTM designations were established in accordance with Practice B275. ANSIdesignations were established in accordance with ANSI H35.1/H35.1 (M). UNS designations were established in accordance with Practice E527.E”Others” includes listed elements for wh
33、ich no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements notspecified in the registration or specification. However, such analysis is not required and may not cover all metallic “other” elements. Should any analysis by the produceror t
34、he purchaser establish that the aggregate of several “others” elements exceeds the limit of the “Total” the material shall be considered non-conforming.FThe sum of those “others” metallic elements 0.010 percent or more, each expressed to the second decimal before determining the sum.GWith respect to
