1.1 This test method is a small-scale test for obtaining information regarding the free-swelling properties of a coal. The results may be used as an indication of the caking characteristic of the coal when burned as a fuel. This test is not recommended as a method for the determination of expansion of coals in coke ovens.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
