The Test Codes and Schedule in the Paper & Paperboard Program have changed.
CTS is updating all existing Test Codes in the Paper & Paperboard Testing Program. Test Codes are now four-digit numbers, updating from three-digit numbers.
The implementation of this update allows CTS to add new tests and to expand our Paper Program to meet participant needs.
The new, four-digit Test Codes will be in use as you enroll in testing and when claiming data entry on the CTS Portal. Please be aware that the numerical order has shifted as a result of this update.
In conjunction with the Test Code change, the Paper Program Schedule has also changed. Tests will still be conducted every other month. Since testing properties in the new schedule are now comingled, the Original S & G cycles will no longer be used. The new cycles will now be referenced as Odd Month Cycles and Even Month Cycles.
Below is a list of all available tests with their new test codes to aid you in comparing the old test codes to their updated counterparts.
