[Star Wars] If Anakin, Obi-Wan, Ahsoka, and several clones were willfully carbon frozen for a mission, why did Vader need to test the process on Han Solo?

Anakin and his allies deliberately undergo carbon freezing so that they may hide from life form scanners and rescue Even Piell from the Citadel. Since they all survive the process with negligible discomfort upon thawing, what made Darth Vader decide that the freezing needed to be tested on Han Solo to make sure a living subject could survive?

Remember in ESB, Vader says "These facilities are crude, but they should suffice". The facilities he was talking about were not designed for doing live specimens. That part was being cobbled together as they spoke.
