I have a bullion bar with no serial code. How is this bar matched with the test results?

Tested bullion is marked with a Tamper Proof Label (TPL) which references the test result ID. The TPL ID is in turn specified on the Test Report for cross referencing and redundancy purposes. The TPL is a custom label that is attached to the bullion during testing which invalidates itself upon removal by leaving “VOID” marks across the label.

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. This means that there is no need to rely on printed test results as the online check is quick and easy. This is also a strong form of security against the possibility of somebody forging printed test results.
