Determination of Gold in Bullion by Cupellation

    2014 Annual Fee: $1,611.00

    2015 Annual Fee: $1,643.00

    Schedule: May and November



    ABOUT THE PROGRAM

    Fire assay cupellation has been used by gold refiners, fabricators, mines, and mints for the analysis of gold in bullion. This program provides participating laboratories the opportunity to evaluate the accuracy of their assays, using a clear and defined standardized testing procedure. Over 30 laboratories participate in the program. ASTM's Committee E01 on Analytical Chemistry of Metals, Ores, and Related Materials, consisting of over 190 members and developer of over 140 standards, provides the technical direction for these programs.

    The data generated will be statistically analyzed. Final summary reports, provided to participants only, contain:

    • Each participating laboratory's test results (coded for confidentiality)
    • Statistical analysis of test data
    • Charts plotting test results versus laboratory code

    We will accept registration for this program until April 1st to participate in the May and November test Cycles. Orders received after April 1st will only be able to participate in the November test cycle at full price.

    Exception: Proration of your fee for the program is made for those companies participating in the program for the first time.

    TEST SAMPLES

    Test samples are provided by the Metalor USA Refining Corp. The samples provided are homogeneity tested in accordance with Part A of ASTM E 1335 Test Methods for Determination of Gold in Bullion by Cupellation. At the conclusion of testing, laboratories keep the remaining test sample material. Samples are wire (<2mm) or pin tube and are representative of the following concentration ranges of gold: high-range, 90-99 percent Au, 5-9 percent Ag, 0-3 percent Cu; mid-range, 60-90 percent Au, 10-40 percent Ag, 1-5 percent Cu; low-range, 25-60 percent Au, balance Ag, 1-5 percent Cu. Each lab receives two samples each test cycle with one sample each from two of the three ranges above.
