So, that was what I've read too, for homologue the international championship title is needed IPO1 or Sch1 or 40km endurance.
Thanks for your answer
I agree that run 40km not select behaviour, but select the capacity of the body for work, that is too important as the character.
What's the point to have a dog with super character that isn't able to run few kilometers to catch a bandit and fight with full power, or maybe to walk long and dificult path's for rescue lost people?
Have a dog with bad body and no endurance at work is too bad and even more dangerous than have a dog with no caracter for "work", the dog without behaviour will simply not be used, the dog without resistence will be and can cause some serious problems because this.
Of course I agree that endurance test cannot be considerate exactly a working test because the dog only run, but it test the body capacity of the dog to work, and that is important too seing that some dogs loose their ability to work because the bad selection that only had eyes to win dogshows and impressing judges.
Oterwise, at GSD we can see some show dogs with no behavior even for protect his own territory, with titles as Sch1 or IPO1 only for get the homologation of the Internationa champion, dog's like that never will have body capacity to run as will never work, but can do a very beautifull show at working test in basic level.
In French ( and I think have other countries too) is forbidden to make protection work with CzW (and other breeds), so, if this option of the endurance test not exist these people will never be able to get international champion with their dog's.
