and finally with alcohol. The crucible and contents shall be dried
in an oven maintained at 60C. plus or minus 5C. for 30
minutes, cooled in a desiccator and weighed. The loss in weight
shall be calculated as the percentage of tetracene in the sample on
a dry basis as follows:
Tetracene, percent =
(C-D)1OO
