9.6 Remove the piston from the bore (see Note 12). Within
60 seconds, charge the cylinder with a weighed portion of the
sample in accordance with the expected flow rate (as given in
Table 1), reinsert the piston and add the appropriate weight.
The charging weights given in Table 1 are merely suggestions,
and the actual charging weight for a specific sample, if not
known, will need to be determined by trial and error. Adjust the
charge weight so that the piston is in the proper position at the
end of the pre-heat period. If necessary, it is acceptable to
purge excess material from the cylinder bore so that the piston
is in the proper position at the end of the pre-heat period.
Purging of material done at conditions with greater force than
testing conditions shall be completed at least 2 min prior to
making the initial cut-off (see Note 13).
