Narrative:
On descent, we were given a qnh of 992 hpa. The captain read back 29.92 inches. I corrected him twice. I set 992 hpa and did not notice that he failed to set anything as the aircraft passed through 4000 ft. When we were approximately 500 ft low, I realized he still had standard set on his altimeter. I turned off the autoplt and climbed back to 4000 ft. I tried to get the captain to set 992, but he still thought we should be on 29.92 inches. After we were queried by approach did he ask for the altimeter and then he set 992. I should have been more forceful in getting him to set 992. I should have also involved the jump seat pilot. I was on an IOE, so I was very new in the airplane.
