a Elements not included in this Table shall not be intentionally added to the steel without the agreement of the purchaser, except for elements which may be added for finishing the cast. All appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steelmaking process.

b The content of these elements need not be reported unless intentionally added to the cast.

c Option 2: In order to facilitate subsequent forming operation, an agreed maximum copper content lower than indicated and an agreed specified maximum tin content shall apply.

d This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements which shall be reported.
