Procedure6.1 Loose PeatRemove the material from the bag orcontainer, pass it through the 12.5-mm (12-in.) sieve and placedirectly into the measu
10、ring box. Pour the contents fromapproximately 2 ft into the measuring box. Determine thecontents of the bag or container only once. The corners of themeasuring box shall be well filled by shaking with a rotarymotion, one rotation per second for 5 s without lifting the boxfrom the floor or other surf
11、ace. When filled, level it off by astraightedge to determine the volume.6.2 Baled PeatThe volume of baled material shall be theproduct of the height by the area of the base. Measurementsmust be corrected for outside wrappers. Determine the amountof loose peat in a bale by passing through the 12.5-mm
12、 (12-in.)sieve and measuring the amount of loose peat using the 12 by12 by 12-in. box and the procedure described in 5.1.7. Report7.1 Report the volume of peat in cubic feet.8.
