A Small-Scale Test for Free-Swelling Index of Coal

Details

• Personal Author:
  Abernethy RF ; Snyder JP
• Description:
  A small-scale method was developed for determining the free-swelling index of coal samples of limited quantity, especially the macerals. Results of a series of tests using a 0.3-Gram sample correlated well with those by the standard method using a 1-gram sample. The standard and small-scale methods are modified to give unrestricted swelling for those coals having swelling index numbers above 7. [Description provided by NIOSH]
