16、y ofOrganic Compound Emitted by Paint, Ink, and OtherCoatings3. Summary of Test Method3.1 This procedure measures the loss of VOC from a freshlycoated surface by; (a) determining the difference in weight ofa coated test panel before and after various steps in a process,(b) analyzing a sample of the
17、applied coating for VOC or watercontent, or both, by gas chromatography (GC), or Karl Fisher,or both, before and after various steps in a process, and (c)calculating the VOC directly or after subtracting the watercontent. With these analyses, it is possible to relate the VOCloss to the volume of sol
18、ids deposited on the test panel at eachstep of a process. The information obtained is used to deter-mine the amount of VOC available for removal by the VOCcontrol device at each step of a process (see Fig. 1).4. Significance and Use4.1 This test method provides basic engineering data thatmay be used
19、 to determine the amount of VOC delivered to theinlet of a VOC control device. The procedure is useful forestablishing the quantity of VOC that is evolved from thecoating in the flash zone or bake oven and available to beincinerated, although the same procedure can be followedwhen other forms of VOC
20、 abatement are used.4.2 The total amount of VOC removed from the process bythe VOC control device is a function of the amount available asgiven by this test method combined with the VOC removalefficiency of the control device.5.
