Get a hinge that able to withstand the heavy weight of the door . FR door are supposed to be paired with heavy duty hinges only , or best fire tested hinges that comply with the regulations. At least is a sign the door could be fire-rated, as FR door are heavier . If it is hollow and light or with more than 10mm gap at the bottom and 5mm gap at the edge. Seek a refund. Unless their test report is able to prove the door they test is the same. Firedoor with just PSB label at the edge is not enough, without company seal at the edge, as these doors are checks randomly only. Doors without company label does not comply to the standard set by authorities. And is freaking expensive to get one unbranded. If unsure ask them for their test report. Best google first, then buy. I got mine replaced after getting my flat. Realised there are many unbranded ones or unlicensed ones in the market. Some door manufacturers want to save money on materials and labour cost .
