The cutting of the support to obtain the specimen shall not be accomplished by use of heat such as hot wires, heated knives, etc. A knife with a serrated edge has been found to be adequate for this purpose. The specimen shall be weighed t

Add the specimen to the flask and assemble the cover as soon as the specimen is in place. A maximum of five (5) minutes
25、 is allowed from the time when the insert is removed from the polyethylene bag to the time when the cover is assembled to the test flask. If this time period is exceeded, discard the contents of the test flask, the test shall not be completed, and a replacement insert and a specimen shall be selecte
26、d and prepared, adhering to all of the requirements for selecting and preparing the original sample and specimen. The toluene solution contain- ing water from the specimen shall be refluxed by the appli- cation of heat to the test flask until the water level in the distillation trap maintains a cons
27、tant level for i5 minutes minimum. The system shall then be allowed to cool to ambient temperature. Then, 40 to 50 milliliters of toluene, in 10 milliliter increments, shall be poured down the condenser to rinse any water droplets from the surface. The distillation trap shall then be removed from th
28、e system, its contents stirred to assure conlplete separation of the toluene and water. The volume of the water shall be observed and recorded 4.5.1.2 Test procedure. - In general, the precautions, calibra- 14 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from
