scope:

1.1 These test methods cover the chemical analysis of chromium and ferrochromium having chemical compositions within the following limits:

  Element Composition, %
  Aluminum 0.25 max
  Antimony 0.005 max
  Arsenic 0.005 max
  Bismuth 0.005 max
  Boron 0.005 max
  Carbon 9.00 max
  Chromium   51.0 to 99.5
  Cobalt 0.10 max
  Columbium 0.05 max
  Copper 0.05 max
  Lead 0.005 max
  Manganese 0.75 max
  Molybdenum 0.05 max
  Nickel 0.50 max
  Nitrogen 6.00 max
  Phosphorus 0.03 max
  Silicon 12.00 max
  Silver 0.005 max
  Sulfur 0.07 max
  Tantalum 0.05 max
  Tin 0.005 max
  Titanium 0.50 max
  Vanadium 0.50 max
  Zinc 0.005 max
  Zirconium 0.05 max

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.
