scope:
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:
Section Aluminum: Benzoate-Oxinate (Gravimetric) Method 8 to 15 Sodium Hydroxide (Potentiometric) Method (Op- tional Routine Method) 16 to 23 Copper: Neocuproine (Photometric) Method 24 to 33 Hydrobromic Acid-Phosphoric Acid (Photometric) Method 34 to 43 Iron by the 1,10-Phenanthroline (Photometric) Method 44 to 53 Lead by the Dithizone (Photometric) Method 54 to 63 Magnesium---Analysis
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.
