CTS Test Tool

The STS Association has published a Certification tool to enable members to determine which tests are applicable to their meters. The tool allows the member to select their meter or vending system type and support options, and generates a report listing all the relevant documents and test numbers required for compliance. While every effort has been made to ensure accuracy in the test report, the STSA cannot guarantee that all reports are completely accurate - please refer to the STS test documents if in doubt. Please report any inconsistencies to the STSA so that the errors may be rectified. Note that this tool refers specifically to the STS531 set of test documents, which will be published by the end of February 2015., which will be published by the end of February 2015.
