As of today, after extensive beta testing, we have launched the DUX Bullion Testing services at our office/depository in Certis Cisco, Paya Lebar to the public.
DUX offers a fast, accurate and comprehensive method to test bullion by utilizing a combination of three different non-destructive tests whose results are automatically uploaded through our custom developed software into a database. The results are evaluated against allowable tolerances as defined for the type of bullion being tested.
DUX is an acronym that stands for Density Ultrasound and X-ray Fluorescence testing. Each test measures and compares a different physical characteristic (mass and volume, ultrasound celerity, and surface metal composition) in such a way that counterfeit bullion might pass an individual test but not the DUX trio of tests (find out more).
DUX Bullion Testing has been in development for over six months, during which time we have acquired and customized the equipment and necessary regulatory permits to operate two X-ray spectrometers, three ultrasound readers with different aperture probes (for coins and bars), as well as trade approved scales, including highly accurate electromagnetic force compensation scales. The DUX hardware expenditure alone represents an investment of over 90,000 SGD (73,000 USD).
Over the past few months, we were able to demonstrate the process on genuine and gold plated tungsten test bars to several mints and major bullion dealers as well as an LBMA Referee and have consistently received praise and approval of these processes. The recognition is a huge step forward and we believe that DUX will become the leading industry standard for non-destructive bullion testing.
You can make an appointment via e-mail at [email protected] or call us to schedule for a DUX bullion test or simply visit as a walk in customer with the bullion to be tested.
Standard price is 50 SGD for Silver Bullion or Certis Cisco customers (60 SGD for non-customers). The process normally takes 10 to 15 minutes to complete. This compares well with traditional tests which normally cost more than 200 SGD and may involve traditional (destructive) forms of testing.
Tested bullion can be optionally marked with a Tamper Proof Label (TPL) which references the test results. The TPL ID is in turn specified on the Test Report for cross reference and redundancy purposes. Test Report data will also be retrievable online in the near future so that the TPL on the bullion can be keyed in to review test results.
A DUX Bullion Test result is organized as follows:
