ASTM D5087-02 (R2021) pdf free download.Standard Test Method for Determining Amount of Volatile Organic Compound (VOC)Released from Solventborne Automotive Coatings and Available for Removal in a VOC Control Device (Abatement).
1.1 This test method covers the determination of the amount of volatile organic compound (VOC) released from applied solveniborne automotive coatings that is available for delivery to a VOC control device. This is accomplished by measuring the weight loss of a freshly coated test panel subjected to solvent evaporation or baking in a laboratory simulation of the production process.
1 .2 This test method is applicable to the VOC released from flashofi’ and baking operations after the paint has been applied.
1.3 This test method is applicable to solventborne automotive coating materials and is intended to represent or simulate the production process. The same general principles apply to waterborne coatings that contain volatile organic compounds (VOC). although specific procedural details are not presented herein to differentiate between VOC and water.
3. Summary of Test Method
3.1 This test method simulates the loss of VOC from a freshly coated surface by using the difference in weight of a coated test panel before and after baking. Metal test panels are subjected to a simulation of the production coating process including application, flashing, and baking. The weight loss value obtained is then related to the volume of solids deposited on the test panel to compute the number of pounds of VOC per gallon (grams per litre) of solids applied that is available at the inlet of the VOC control device.
3.2 The information needed to determine the amount of VOC available for removal by the VOC control device is determined by identification of the points in the production process at which coated objects would enter Ilashoff/baking zones whose effluents are vented to the VOC control device.
4. Significance and Use
4.1 This test method provides basic engineering data that may be used to determine the amount of VOC available for delivery at the inlet of a VOC control device (particularly for the automobile industry).6 Typically, the procedure is useful for establishing the quantity of VOC that is evolved from the coating in the baking oven and available to he incinerated, although the same procedure can be followed for other forms of VOC abatement (that is, carbon, adsorption. etc.).
4.2 This test method may be adaptable for use directly in a production environment if all the critical factors (for example, temperature, cleanliness, vibration, accessibility, etc.) can be adequately controlled.
4.3 The total amount of VOC removed from the process by the VOC control device is a function of the amount available as given by this test method combined with the VOC removal efficiency of the control device.ASTM D5087 pdf download.
