Youn nan fason ki pi senp yo fè yon tès flanm dife se koupe yon echantiyon nan plastik la epi limen li nan yon kofr lafimen. Koulè flanm dife a, sant ak karakteristik boule yo ka bay yon endikasyon ki kalite plastik: 1. Polyethylene (PE) - Degoute, odè tankou sire chandèl;
2.Polypropylène (PP) - Degoute, odè sitou nan lwil motè sal ak undertones nan sire chandèl;
3. Polymethylmethacrylate (PMMA, "Perspex") - bul, krak, bon sant aromat;
4. Polyamid oswa "Nylon" (PA) - Flanm dife swi, odè marigold;
5. Acrylonitrilebutadienestyrene (ABS) - Pa transparan, flanm swi, odè marigold;
6. Polyethylene kim (PE) - Degoute, odè sir chandèl
