IL. The blocks ready for use must
meet the indentation test pressure
made a" follows: The blocks to be
tested are first dried at 400 degrees F.
during IL hourss Then "a polished
steel die 1 inch square on its .Slower
face, square edges, corners and per-
pendicular sides, is placed on dried
block firmly supported in IA Soompfes-
sion testing machine. A pressure of
5000 pounds is applied sql1icklys i and
maintained exactly one minute, The
die must not descend and indent the
block more than one-eighth of an inch.
The measurements are. to be taken
from when the die is lightly pressed
against the block to the instant the
5000 pounds pressure has been ap-
piled one. minute. The die is placed
anywhere within one-half on inch of
the edges of the block and so as to
compress lengthwise the wood fibres,
