Standard Test Methods for Chemical Analysis of Chromium and Ferrochromium

Significance and Use

4.1 These test methods for the chemical analysis of chromium metal and ferrochromium alloy are primarily intended to test such materials for compliance with compositional specifications such as Specifications A101 and A481. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.

Scope

1.2 The analytical procedures appear in the following order:

 

Sections

Arsenic by the Molybdenum Blue Spectrophotometric Test Method
 [0.001 % to 0.005 %]

10 – 20

Lead by the Dithizone Spectrophotometric Test Method
 [0.001 % to 0.05 %]

21 – 31

Chromium by the Sodium Peroxide Fusion-Titrimetric Test Method
 [50 % to 75 %]

32 – 38

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6 and in special ”Warning” paragraphs throughout these test methods.
