1、Designation: D 2978 03Standard Test Method forVolume of Processed Peat Materials1This standard is issued under the fixed designation D 2978; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in par

Scope*1.1 This test method covers the measurement of the volumeof loose and baled processed peat expressed as cubic feet.21.2 This standard does not purport

3、 to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Test Method

5、3.1 The test method consists of dividing the particles of peatby passing them through a 12.5-m (12-in.) sieve and allowingthem to fall into a volume-measuring container.4. Significance and Use4.1 This test method may be used to quantify the volume ofpeats under consideration in commercial transactio

Reliable results depend on manyfactors; Practice D 3740 provides a means of evaluating someof those factors.5. Apparatus5.1 U. S. Standard Sieve, 12.5-mm

Procedure6.1 Loose PeatRemove the material from the bag orcontainer, pass it through the 12.5-mm (12-in.) sieve and placedirectly into the measuring

10、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 surface.

11、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. Precision and Bias8.1 PrecisionDue to the nature of the soil or rock mate-rials tested by this method it is either not feasible
