ASTM E62-89(1996) PDF

1.1 These test methods cover photometric procedures for the chemical analysis of copper and copper alloys having chemical compositions within the following limits:

Copper, % 50 and over Tin, % 0.0 to 20 Lead, % 0.0 to 27 Iron, % 0.0 to 4 Manganese, % 0.0 to 6 Silicon, % 0.0 to 5 Aluminum, % 0.0 to 12 Nickel, % 0.0 to 5 Sulfur, % 0.0 to 0.1 Phosphorus, % 0.0 to 1.0 Arsenic, % 0.0 to 1.0 Antimony, % 0.0 to 1.0 Zinc remainder

1.2 The analytical procedures appear in the following order:

Antimony by the Iodoantimonite (Photometric) Test Method 70 to 79 Arsenic in Fire-Refined Copper by the Molybdate Test Method 60 to 69 Iron by the Thiocyanate Test Method 1a Manganese by the Periodate Test Method 41 to 48 Nickel by the Dimethylglyoxime-Extraction Photometric Test Method 1a Phosphorus by the Molybdivanadophosphoric Acid Method: Deoxidized Copper and Phosphorized Brasses 17 to 24 Copper-Base Alloys Containing 0.01 to 1.2% Phosphorus 25 to 33 Tin by the Phenylfluorone Photometric Test Method 80 to 90 Silicon by the Molybdisilicic Acid Test Method 49 to 59
