"Other individual elements or other totals": The chemical composition includes elements not specified in the table. Analysis should only be conducted if these elements are suspected to be present, or if routine analysis suggests that their content may exceed the prescribed limits.

◎ The mass fraction of copper and nickel in titanium and in all alloys shall be not more than 0.10 % (in total), including not more than 0.08 % nickel.

• In all alloys containing molybdenum as an alloying element, its partial replacement with tungsten is allowed in the amount of no more than 0.3%. The molybdenum and tungsten total mass fraction shall not exceed the norms specified in the table for molybdenum.
