    1. Chromium by the Diphenylcarbazide Photometric Test Method (0.004% to 0.04 %)
    2. Iron by the 1.10-Phenanthroline Photometric Test Method (0.05% to 0.25%)
    3. Manganese by the Periodate Photometric Test Method (0.008% to 0.04 %)
    4. Nickel by the Dimethylglyoxime Photometric Test Method (0.001% to 0.04 %)

    What is the scope of ASTM E439?

    These ASTM E439 test methods for the chemical analysis of beryllium metal are primarily designed to be referee procedures for testing such materials for compositional conformity. These test methods cover the chemical analysis of beryllium having chemical compositions within the following limits:

    ASTM E439 Testing Procedure and Requirements

    A standard UV/Vis spectrophotometer is required to monitor absorbance at these exact target wavelengths to measure composition limits. The ASTM E439 specifies the following test procedures:

    1. Chromium by the diphenylcarbazide (photometric) test method:  Chromium is oxidized by peroxydisulfate in the presence of silver nitrate in this test procedure, and the chromium diphenylcarbazide complex is subsequently formed. Photometric measurements are taken at 540 nm.
    1. Iron by the 1,10-phenanthroline photometric test method: Iron is reduced with hydroxylamine hydrochloride and transformed to the 1,10-phenanthroline complex in this test procedure. Photometric measurements are taken at 515 nm.
    1. Manganese by the periodate photometric test method: Manganese is oxidized to permanganate with potassium periodate in a nitric-sulfuric-phosphoric acid medium in this test procedure. Photometric measurements are taken at 525 nm.
    1. Nickel by the dimethylglyoxime (photometric) test method: Nickel is precipitated from an ammoniacal solution using 1,2,3-benzotrazole using cadmium as a carrier, in this test procedure. Following filtration, the paper and residue are washed with HNO3 and HClO4. In an alkaline medium, the nickel is oxidized by potassium peroxydisulfate, resulting in the formation of the nickel dimethylglyoxime hue. Photometric measurements are taken at 465 nm.

    ASTM E439 Result Analysis and Interpretation

    The net photometric reading of the test solutions is converted to milligrams of chromium, iron, manganese, and nickel using their respective calibration curves, according to ASTM E439.
