(3) "emission limit value" means the permissible quantity of a substance contained in the waste gases from the combustion plant which may be discharged into the air during a given period; it shall be calculated in terms of mass per volume of the waste gases expressed in mg/Nm3, assuming an oxygen content by volume in the waste gas of 3 % in the case of liquid and gaseous fuels, 6 % in the case of solid fuels and 15 % in the case of gas turbines;
3) heitkoguse piirväärtus — teatava ajavahemiku jooksul põletusseadmest õhku eralduvas heitgaasis sisalduva aine lubatud kogus; see arvutatakse saasteaine massina heitgaaside mahuühiku kohta, väljendatuna mg/Nm3, kui heitgaasi mahuühiku hapnikusisaldus on 3 % vedel- ja gaaskütuste puhul, 6 % tahkekütuste puhul ning 15 % gaasiturbiinide puhul;
