With that said, it's extremely difficult at any airline to determine runway conditions. Even the aerodata performance book lists specifications for different contaminants. Yet they are measurements in inches. I have never been to an airport that reported contaminant depth. Ultimately it's up to the PIC to determine.
On the 'bus sometime during the arrival phase of flight there's a place for you enter the reported braking action into the MCDU when you state the landing runway conditions - if the numbers say you can't land then you're holding or diverting no matter what anyone tries to tell you. Can't imagine any Captain I know accepting anything less conservative. Been in that situation myself & never experienced any pushback from dispatch.
