Thabhairt isteach a táirge ar an Mír Aonair Burning
An Mír Aonair Burning (SBI), tá modh tástála chun a chinneadh an t-imoibriú a iompar tine de na seachtháirgí (gan urlár) a thógáil nuair a nochtar don ionsaí teirmeach ag mír lasta amháin (dóire gainimh-bhosca a sholáthraítear le própán). Is é an t-eiseamal suite ar tralaí atá curtha i bhfráma faoi bhun sceithchóras. Déantar monatóireacht ar imoibriú an t-eiseamal isteach an dóire instrumentally agus amhairc. Teas agus scaoileadh deataigh rátaí a thomhas instrumentally agus tréithe fisiciúla a mheas trí bhreathnú.
