The stiffening of sanctions brought in last month by the governing body has raised the prospect of a rash of sin-binnings and sendings off in the championship.
Jones, who leads Wales in Italy tomorrow, hopes good sense will prevail with referees but has asked teammates and opponents not to fan the flames.
"Players and fans all have a responsibility when there's a 50-50 not to scream for a yellow card when it's actually a penalty," said Jones. "Nothing has really changed in that you can't tackle people round the head but it's up to the judiciary panels to decide intent, recklessness, etc, not players."

Wales had top referee Nigel Owens in their camp last weekend to go through the directives but Jones believes players will be best served relying on their natural instincts.
"If you go in thinking about it you will do yourself an injustice," he said. "You're going to start missing tackles potentially by trying too hard and putting other people in your defensive line under pressure."
Recent Six Nations history favours an emphatic Wales win – they topped 60 points on each of their last two outings against the Azzurri – and with bonus points now available for the first time for four tries that should be Wales's target in Rome.

But as the only surviving starter from the Wales team beaten by Italy in Rome ten years Jones remains wary.
"I have had the experience to be out there and lose so I know both sides of the coin," he said.
Italy's new boss Conor O'Shea says Jones is right to be cautious. "It is possible to change our history and we want a great, great performance this weekend to make everybody understand we are on the right track," he said.
