Ingcamango yoVavanyo oluBandakanya ilangatye

Uvavanyo lokulinganisa ilangatye oluthintela ilangatye yindlela esetyenziselwa ukuvavanya amandla ezinto zokumelana nokusasazeka kwelangatye. Imigangatho eqhelekileyo ibandakanya i-UL94, i-IEC 60695-11-10, kunye ne-GB/T 5169.16. Kwi-UL94 eqhelekileyo,Uvavanyo lokutsha kwezinto zeplastiki kwiindawo zezixhobo nakwizixhobo, ukulinganiswa kokurhoxiswa komlilo kwahlulwe ngokwamanqanaba ali-12 ngokusekwe kubunzima bovavanyo kunye nokusetyenziswa kwalo: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, kunye neHF2.

Ngokubanzi, izilinganiso ezisetyenziswa rhoqo zokurhoxisa ilangatye ziqala kwi-V-0 ukuya kwi-V-2, apho i-V-0 ibonisa ukusebenza kakuhle kokurhoxisa ilangatye.
