GOST 32977-2022 PDF

Scope: This standard applies to hard and brown coals, lignites, anthracites, oil shale, coke, peat, fuel briquettes, products of enrichment, processing and combustion of solid mineral fuels (hereinafter referred to as solid fuels) and establishes a method for determining trace elements such as beryllium, chromium, manganese , copper, nickel, vanadium, lead and zinc in solid fuel ash by atomic absorption spectrometry with flame atomization. When solid fuel is ashed in a laboratory electric furnace at a temperature of 500 °C, the indicated trace elements are quantitatively transferred into ash, therefore the content of trace elements found in the ash can be recalculated to the original fuel
