"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.
ⓐ “Others” does not include modifying or refining elements such as Na, Sr, Sb and P.
ⓑ Refining agents such as Ti, B or master alloys containing nucleating particles such as TiB₂ shall not be considered as impurities. Nevertheless, the minimum and maximum content of refining elements should be agreed between the manufacturer and the purchaser.
ⓒ European Regulations and Directives need to be taken into account. See [7] to [10] for information.
