Mercedes says its reprimand and ban from the Formula 1 young driver test is a "proportionate" punishment for its tyre test with a 2013 car.
The FIA International Tribunal ruled that Mercedes and Pirelli's actions in running for three days at Barcelona in May had breached the rules, but accepted that the team had acted in good faith.
Mercedes issued a statement confirming it saw no need to appeal the decision and felt it was fair.
"The decision of the International Tribunal confirmed that the team acted in good faith regarding the Pirelli tests, never intended to obtain any unfair sporting advantage and had no reason to believe that approval for the Pirelli tests had not been given," it said.
"Mercedes accepts the proportionate penalties of a reprimand and suspension from the forthcoming young driver test that have been decided upon by the Tribunal.
"Mercedes would like to once again restate its firm belief in proper due process and commend the FIA for the principle of an independent disciplinary body.
"The team would furthermore like to thank the International Tribunal and its president for the fair hearing it received yesterday.
"In the best interests of the sport, the team does not intend to avail itself of any right to appeal the decision."
Pirelli had argued that the current testing restrictions made it impossible to properly evaluate its tyres, and Mercedes echoed calls for changes to tyre testing.
"Mercedes looks forward to working with the FIA and its fellow competitors to establish a more rigorous procedure for testing in the future, particularly to support the appointed tyre supplier," said the statement.
"We now wish to bring this matter to a close and focus on the forthcoming British and German Grands Prix."
