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 be 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.
Scope
1.1 This test method covers the determination of the amount of volatile organic compound (VOC) released from applied solventborne 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 flashoff 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.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
