Sets out a method for preparing the charge and producing coke in pilot-scale coke ovens having widths approximating a commercial by-product battery oven and methods for preparing such cokes for testing.

This Standard recommends the method of preparing the charge and producing coke in pilot-scale coke ovens having widths approximating a commercial byproduct battery oven (e.g. 350 mm to 500 mm), and the methods of preparing such cokes for testing.
