3、bes a procedure for the labora-tory determination of the concentration of nitroaromatic andnitramine explosives in soil.The explosives involved in thistest method are as follows:HMX(octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine),RDX(hexahydro-1,3,5-trinitrol-1,3,5-triazine),TNT(2,4,6-trinitrotolu
4、ene),TNB(1,3,5trinitrobenzene),DNB(1,3 dinitrobenzene),tetryl(methyl-2,4,6-trinitrophenylnitramine),and2,4-DNT(2,4-dinitrotoluene).1.2 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.2.1 The procedures used to speci
5、fy how data are collected/recorded or calculated,in this standard are regarded as theindustry standard.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
6、studies,or any consider-ations for the users objectives;and it is common practice toincrease or reduce 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.
7、1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address the safetyconcerns associated with its use.It is the responsibility of theuser of this standard to establish appropriate safety and
