BS ISO 567:2021 pdf download.Coke — Determination of bulk density in a small container This document specifies a method for the determination of the bulk density of coke in a cubical or cylindrical container of small capacity (0,2 m 3 ). It is applicable to coke with a nominal top size not greater than 125 mm. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

The exact volume of the small container shall be known. The container shall be waterproof and be resistant to deformation. A 200 l container (44 gallon drum) or a 100 l container is suitable for this purpose. A 44 gallon drum sliced to a height of 50 % is also suitable for this purpose. 5.2 Mass determination scale/machine, preferably of the platform type, of minimum capacity  200 kg and sufficiently accurate that the mass determination error does not exceed 0,1 % of the maximum load or 250 g, whichever is the smaller. 6 Test sample Take a representative sample in accordance with ISO 13909‑5 or ISO 18283. It is recommended that enough sample is taken to allow...
