SCOPE1.1 This is a general method for determin-ing the moisture in pyrotechnics which donot react with the Karl Fischer reagent andfrom which the moisture is easily extract-able.Note. Al

36、though the application of the Karl Fischerreagent for determining the moisture content ofpyrotechnics is general in scope, its chemical activi-ty with materials other than moisture imposes cer-tain limitations that must be taken into account bymodification of the method for the purpose of adap-tion

37、to specific applications. Detailed specificationsshould be consulted for adaptations to materials thatrequire modifications of the procedure listed herein.2. SPECIMEN2.1 The specimen shall consist of approxi-mately 8 to 10 gm of the pyrotechnic.Note. The specimen shall contain not more than0.01 gm o

38、f water, The specimen weight should beadjusted after a preliminary determination, so thatthe water will not exceed 0.01 gm.3.
