I don’t know the legislation word by word but I do know it requires that the repair is possible without specialised equipment. How should a simple consumer without special tools apply a precise torque.
Changing a phone battery should be simpler than repairing a car and the regulation also requires it to be simpler.





There are two possibilities. Either the right torque is critical for successful repair. In which case skill is required with simple equipment that cannot be expected from a simple consumer, or the torque has such a high tolerance that the error margin is what a regular screw driver use would comply with, and therefore no torque has to be specified in the repair manual, other than maybe qualitative statements.
