A test portion is deated in a tared platinum crucible, in a furnace at 700 degrees centigrade, under oxidizing and specified conditions, to constant mass. The residue is cooles and weighed. The method is applicable to products (tar pitch, petroleum pitch, etc.) producing a quality of ash greater than or equal to 0,05 % (m/m).
Abstract
Overview
ISO 8006:1985 applies to carbonaceous materials used in aluminium production - specifically (tar pitch, petroleum pitch, etc.) - and specifies a gravimetric method for the . The method is intended for products that yield an ash content greater than or equal to 0.05 % (m/m). The procedure uses a tared and controlled oxidizing incineration in a furnace at 700 ± 10 °C until constant mass is achieved.
