BS ISO 15117-1:2004

This standard BS ISO 15117-1:2004 Coal flow properties is classified in these ICS categories:

• 73.040 Coals

This part of ISO 15117 sets out methods for the measurement of the flow properties of coal, primarily for the design of bins and chutes. It also provides some guidance on the presentation of these data for analysis and design.

This part of ISO 15117 consists of a bulk density test and a yield locus test giving information on material flow properties. It also describes a further test, called the wall yield locus, which measures the friction between coal and bin wall material.

Although this part of ISO 15117 is nominally for coal, the principles and apparatus may be used for coke and other semi-cohesive particulate materials where a knowledge of flow properties is required.

NOTE Some discussion of the relevance of coal flow properties to bin design philosophy is provided in Annex A.
