1、Designation:D297815Standard Test Methods forVolume of Processed Peat Materials1This standard is issued under the fixed designation D2978;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 parenthese
2、s indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 These test methods cover the measurement of thevolume of loose and baled processed peat expressed as cubicfeet and is used as a quality control measurement to
3、 determineif the package contains the labeled amount of material.Theresults of these test methods are highly dependent on theexperience of the personnel running the procedure.1.2 There are two test methods,Method A for Loose Peatand Method B for Baled Peat.Method A is used when thematerial is uncomp
4、acted and Method B is used when thematerial is compacted.1.3 UnitsThe values stated in inch-pound units are to beregarded as standard.Except,that the sieve designations aretypically identified using the“alternative”system in accor-dance with Practice E11,such as 3-in.and No.200,instead ofthe“standar
5、d”of 75-mm and 75-m,respectively.1.4 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.4.1 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as theindustry stan
6、dard.In addition,they are representative of thesignificant digits that generally should be retained.The proce-dures used do not consider material variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives;and it is common practice toincrease or re
7、duce significant digits of reported data to becommensurate with these considerations.It is beyond the scopeof this standard to consider significant digits used in analysismethods for engineering design.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its
8、 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.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD3740 Practice f

11、 of compacted peat(Method B)or dividing theparticles of uncompacted peat(Method A)by passing themthrough a12-in.(12.5-mm)sieve and allowing them to fall intoa volume-measuring container.5.Significance and Use5.1 These test methods are used to quantify the volume ofpeats under consideration in commer
12、cial transactions to deter-mine if the package contains the labeled quantity.As such,material comes into the test area in an“as sold”condition.NOTE1The quality of the result produced by this standard isdependent on the competence of the personnel performing it,and thesuitability of the equipment and
13、 facilities used.Agencies that meet thecriteria of Practice D3740 are generally considered capable of competentand objective testing/sampling/inspection/etc.Users of this standard arecautioned that compliance with Practice D3740 does not in itself ensurereliable results.Reliable results depend on ma
