A320 FO REPORTS DISAGREEMENT WITH CAPT OVER COMPLIANCE WITH COMPANY REQUIRED ENGINE WARM-UP BEFORE TKOF.

Narrative

WHEN A SINGLE ENG TAXI WAS COMMANDED BY THE CAPT; I BROUGHT UP THE 5 MIN WARM-UP. ON J; WHEN WE STARTED THE ENG; I MENTIONED THE 5 MIN WARM-UP AGAIN. PER SOP; I STARTED TIMING FOR THE 5 MINS AFTER THE ENG STABILIZED VERBALIZING WHAT I DID. IT WAS NO SURPRISE TO ME THAT WE ARRIVED AT RWY 9R WITH JUST ABOUT 3 MINS LEFT ON THE WARM-UP. WHEN TWR CLRED US INTO POS AND HOLD; I ACCEPTED THE CLRNC AND INFORMED THEM THAT A FEW MINS WERE NEEDED (I CANNOT REMEMBER THE EXACT TIME I GAVE THEM) BEFORE WE COULD TAKE OFF. AT FIRST; TWR CLRED US STRAIGHT AHEAD BUT THEN RESCINDED AND SAID POS AND HOLD. ALL THE WHILE THE CAPT WAS YELLING 'POS AND HOLD' REPEATEDLY. AFTER WE ENTERED THE RWY; TWR CLRLY CHANGED HIS MIND AND TOLD US TO EXIT THE RWY STRAIGHT AHEAD. I REPEATED HIS CLRNC. THE CAPT WHILE STILL YELLING POS AND HOLD; DISREGARD THE CTLR AND TURNED INTO POS. THEN THE TWR CLRED US TO TAXI STRAIGHT AHEAD AND MAKE A R TURN OFF RWY 9R. THE CAPT AGAIN YELLED POS AND HOLD TO ME. I LOOKED AT THE CAPT AND SAID 'COMPLY WITH ATC INSTRUCTIONS AND EXIT THE RWY' PROFESSIONALLY; CALMLY BUT WAS FIRM AS MY HAND WAS GOING TO THE TILLER TO TAKE THE ACFT TO COMPLY. FORTUNATELY; THIS WAS NOT NEEDED AND THE CAPT EXITED THE RWY. CRM: I CANNOT CONCEIVE HOW I COULD HAVE DONE ANYTHING ELSE TO PREPARE THE CAPT FOR THE WAIT. HE DECIDED TO DO A SINGLE ENG TAXI TO RWY 9R FULL WELL KNOWING WE HAD A WARM-UP. IN HINDSIGHT; MAYBE I SHOULD HAVE REQUESTED HE RETURN TO THE GATE OR TAKE SOME TIME TO CALM DOWN. I NOW WONDER WHERE HIS THOUGHTS WERE DURING THE TKOF. I SHOULD ALSO NOTE WE LANDED 15 MINS EARLY AFTER FLYING A LOW COST INDEX. TIME WAS NEVER A FACTOR.
