- Scope
- This method specifies the method for the determination of tin content in copper and copper alloys. Method 1: Zeeman effect electrothermal atomic absorption spectrometry: measurement range: 0.0001% to 0.0020%. Method 2: Phenylfluorone-polyethylene glycol octylphenyl ether spectrophotometry: measurement range: >0.0010% to 0.50%. Method 3: Potassium iodate titration method: Determination range: >0.50%~10.00%.
