1 Scope This standard specifies the determination of boron content in steel by curcumin spectrophotometric method. This method is applicable to the determination of 0.0005 % (m/m) ~0.012 % (m/m) boron content in steel and 0.0001% (m/m) ~0.0005% (m/m) boron content in non-alloy steel. 2 Normative References The following documents contain provisions which, through reference in this text, constitute provisions of this standard. At time of publication, the editions indicated are valid. All standards are subject to revision, and parties concerned are encouraged to discuss the possibility of applying the latest edition of the following standards.

In the acetic acid-acetate buffer solution, the boric acid and curcumin will form colored compound. The photometric measurement is carried out at 543nm wave length.
