1.1本试验方法涵盖使用40°C下1小时的烘烤周期测定糊状非热定型油墨系统的挥发性有机化合物（VOC40）含量。 1.2本试验方法适用于主要通过吸收、聚合或相关方式干燥而无需加热的糊状印刷油墨和载体。此类系统不包含在正常室温下容易蒸发的大量低沸点溶剂。 注1-本试验方法中的40°C烘烤温度与湾区方法30中规定的温度相同。在几种相关试验方法中，加热温度为110°C，例如D2369， D4713 和EPA参考方法24。挥发性有机化合物测定在ASTM手册系列MNL 4中进行了审查。 1.3本标准无意解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This test method covers the determination of the volatile organic compound (VOC40) content of non-heatset printing ink systems of the paste type using a baking cycle of 1 h at 40°C. 1.2 This test method is applicable to paste printing inks and vehicles that dry primarily by absorption, polymerization, or related means without the application of heat. Such systems do not contain appreciable quantities of low-boiling solvents that evaporate readily at ordinary room temperatures. Note 1-The 40°C baking temperature in this test method is the same as that specified in Bay Area Method 30. The temperature of heating is 110°C in several related test methods, for example, D2369, D4713 and EPA Reference Method 24. VOC determinations are reviewed in ASTM Manual Series MNL 4. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
