40/105/56 means the capacitor has been tested between -40 C and +105 C for 56 days.
Same with the 40/85/56.
The ISO/IEC have standard procedures, of which the 56 days is one, that enables someone to compare components.
The main parameters that influence capacitor performance are temperature and humidity.
A standard IEC procedure is placing capacitors in a surrounding with prescribed humidity percentage for 56 days at different temperature.
