Katsekeha koosneb kahest vertikaalselt asetatud ehitusmaterjali proovist, mis on ühendatud täisnurga all. Katsekeha mõjutatakse põleti leegiga, mis paikneb proovide ühenduskoha alumises nurgas. Leegiga mõjutamise aeg on 20 minutit. Parameetrid, mis iseloomustavad toote tuletundlikkust, arvutatakse vastavalt põlemisel kulunud hapniku kogusele ning eraldunud süsihappegaasi kogusele.
