Printable version of the certificate (PDF, 190 kb)

SL-1 was prepared in 1975 from material donated by the Steel Company of Canada Ltd. at Hamilton, Ontario, for use in analytical laboratories associated with the iron and steel industry.

Although the interlaboratory program involving 21 laboratories yielded results for 13 constituents, only 6 met the criteria for certification; values for the other are provisional.
