BS ISO 15585:2019

What is ISO 15585-Determination of caking index about?

ISO 15585 specifies a method of determination of caking index of hard coal.

ISO 15585 is applicable to the evaluation of caking power of bituminous coal with random reflectance of vitrinite, Rr, greater than 0,6 % and less than or equal to 1,8 % (>0,6 % and ≤1,8 %).

Who is ISO 15585-Determination of caking index for?

ISO 15585 - Determination of caking index is useful for:

• Thermal power plants
• Coal processing companies
• Regulatory authorities
• Testing houses

Why should you use ISO 15585-Determination of caking index?

Caking index is a key parameter to identify the caking power of hard coal, which is a measurement of the agglutinating strength between the coal particles and inert constituents after heating without the contact of air. Coal caking characteristic is important and widely used in coking, gasification, liquefaction and combustion industries.

ISO 15585 specifies quality test for standard anthracite used for caking index determination.

ISO 15585 guides you to perform the test for measuring caking index with precision and accuracy.

The caking power of the test sample helps you express the abrasive strength, i.e. resistance to breakage of the crucible coke.

What’s changed since the last update?

BS ISO 15585:2019 supersedes ISO 15585:2006. BS ISO 15585:2019 includes some technical changes with respect to ISO 15585:2006.

These include:

• Change to test precision (both for repeatability, r, and reproducibility, R) resulting from ILS conducted in 2016 and 2017
• Additional information provided on anthracite sample packing and homogeneity test in Annex A and standard deviation formula and flowchart for standard anthracite sample taking in Annex B
