3、lidbyproducts of combustion from boiler furnaces and similarreactors,including ash,flyash,char,slag,and similar materials.1.2 This test method is intended for the use of industry todetermine the performance of boiler furnaces and similarcombustion reactors and aid in determining the quality of theso
4、lid residue from combustion.1.3 This test method comprises the use of any of severalmethods to determine total carbon content combined with anyof several methods to determine carbonate carbon,and thecalculation,by difference,of the combustible carbon remainingin a sample.1.4 Alternatively,this test
5、method applies to the determina-tion of total carbon remaining in a material after acidificationwith strong acid to evolve carbonate carbon.In this case,thecombustible carbon is the total carbon measured in the sampleafter acidification.1.5 The values stated in SI units are to be regarded asstandard
