It comes after a fevered hunt for more possible wreckage on La Reunion island turned up no new clues Sunday, with authorities saying that metallic debris found by locals did not come from an aircraft.
A Malaysian delegation headed by the director general of civil aviation Azharuddin Abdul Rahman and representatives from Malaysia Airlines and judicial officials will meet Monday in a chamber of the three French magistrates assigned to the case.
The flaperon is being examined in a military laboratory in the southwestern French city of Toulouse that specialises in plane crash investigations, with results expected from Wednesday afternoon.
The conclusion should determine if it is a piece of the Boeing 777 Malaysia Airlines Flight 370 which disappeared mysteriously March 8, 2014 with 239 people on board -- and possibly provide some clues to one of aviation's greatest mysteries.

US aircraft manufacturer Boeing will also dispatch a "technical" team to participate in the investigations in Toulouse.
The flaperon will be analysed using physical and chemical methods including "a scanning electron microscope that can magnify up to 100,000 times" to understand how it was damaged, said Pierre Bascary, former director of the tests at France's General Directorate for Armament.
But beyond the flight identification, analyses are unlikely to draw the story of the disaster, experts say.
Meanwhile, locals on La Reunion island have been combing the shores since the wing part was found last Wednesday, handing over bits of what they believe to be wreckage to police.
"There is a sort of 'treasure hunt' mentality that is taking hold and people are calling us for everything," said a local source close to the investigation.
