28、 Analysis 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 present in excess of s

29、pecified limits.B For 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 prescribed in

30、Section 3 of Practice E29.C Limits are in percent maximum unless shown otherwise.D Alloys 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 A413.0 may be m

UNS designations were established in accordance with Practice E527.E ”Others” includes listed elements for which no speci

32、fic 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 the purchaser

33、 establish that the aggregate of several “others” elements exceeds the limit of the “Total” the material shall be considered non-conforming.F The sum of those “others” metallic elements 0.010 percent or more, each expressed to the second decimal before determining the sum.G With respect to mechanica
