其他單個或其他合計化學(xué)成分包括表中未指定值的化學(xué)成分。只有在假定存在或在常規(guī)分析中，且有跡象表明其成分將超過規(guī)定值的情況下，才應(yīng)進(jìn)行分析。 ① At minimum, the analysis of samples from the top and bottom of the ingot shall be completed and reported for all elements listed for the respective grade in this table.
② Final product hydrogen shall be reported. Ingot hydrogen need not be reported. Lower hydrogen may be obtained by negotiation with the manufacturer.
③ Single values are maximum. The percentage of titanium is determined by difference.
④ Other elements need not be reported unless the concentration level is greater than 0.1 % each, or 0.4 % total. Other elements may not be added intentionally. Other elements may be present in titanium or titanium
alloys in small quantities and are inherent to the manufacturing process. In titanium these elements typically include aluminum, vanadium, tin, chromium, molybdenum, niobium, zirconium, hafnium, bismuth, ruthenium,
palladium, yttrium, copper, silicon, cobalt, tantalum, nickel, boron, manganese, and tungsten.
⑤ The purchaser may, in the written purchase order, request analysis for specific elements not listed in this specification.
