PUBLISH DATE 1997
PAGES 17
ASTM E35-88(1997)

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

  • Aluminum, % 0.5 to 12
  • Copper, % 0.005 to 0.1
  • Iron, % 0.002 to 0.1
  • Lead, % 0.001 to 0.5
  • Manganese, % 0.01 to 2.0
  • Nickel, % 0.0005 to 0.5
  • Rare earth elements, % 0.2 to 10
  • Silicon, % 0.01 to 0.8
  • Thorium, % 0.2 to 25
  • Tin, % 0.5 to 10
  • Zinc, % 0.3 to 20
  • Zirconium, % 0.03 to 1.0
  • Magnesium, % remainder

1.2 The analytical procedures appear in the following order:

  • Aluminum: Benzoate-Oxinate (Gravimetric) Method 8 to 15; Sodium Hydroxide (Potentiometric) Method (Optional Routine Method) 16 to 23
  • Copper: Neocuproine (Photometric) Method 24 to 33; Hydrobromic Acid-Phosphoric Acid (Photometric) Method 34 to 43
  • Iron: 1,10-Phenanthroline (Photometric) Method 44 to 53
  • Lead: Dithizone (Photometric) Method 54 to 63
  • Magnesium—Analysis for Manganese and Zinc by Direct Current Plasma Spectroscopy (Proposal) 2
  • Manganese: Periodate (Photometric) Method 64 to 73
  • Nickel: Dimethylglyoxime Extraction (Photometric) Method 74 to 83; Dimethylglyoxime (Gravimetric) Method 84 to 91
  • Rare Earth Elements: Sebacate-Oxalate (Gravimetric) Method 92 to 98
  • Silicon: Perchloric Acid (Gravimetric) Method 99 to 104; Molybdosilicic Acid (Photometric) Method 105 to 114
  • Thorium: Benzoate-Oxalate (Gravimetric) Method 115 to 121
  • Tin: Iodine (Volumetric) Method 122 to 129
  • Zinc: Ethylenediamine Tetraacetate (Volumetric) Method 130 to 137; Potassium Ferrocyanide (Volumetric) Method 138 to 144
  • Zirconium: Alizarin Red (Photometric) Method 145 to 154

1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. Specific precautions are given in Section 5.
