SPECIAL SCHEDULES 
The hardwood and the softwood schedules together cover almost 
the entire temperature range commonly used in kiln drying. The 
values extend from an initial temperature of 105° F. in hard- 
wood Schedule 8 of Table 2 to a final temperature of 210° F. for 
vertical-grain flooring strips in softwood Schedule 000 of Table 4. 
While most drying can be reasonably well done by the use of the
