1.1 这些试验方法包括测定两种印刷油墨中不挥发物的重量含量。 1.2 试验方法A适用于热定型印刷油墨和树脂溶液；此类系统中的溶剂的初始沸点通常在240至275°C（470至535°F）范围内，蒸汽压小于0.2 mm Hg。 1.3 试验方法B适用于基于水或有机溶剂的液体型印刷油墨和载体，这些溶剂在常温下容易蒸发。 注1: 试验方法A（适用于热定型系统）规定了比相关试验方法产生的薄膜厚度薄得多的样品薄膜厚度；一个例外是测试方法中的测试方法B D1259 ，建议作为裁判测试。 注2: 试验方法B（液体油墨系统）与试验方法类似 D2369 但摊铺试样不需要溶剂。 1.4 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.5 本标准并非旨在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、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 油墨的非挥发性成分有助于生产商和用户之间的规格验收。 4.2 为了在规定的3范围内获得热固性系统的准确结果- h加热时间，试样薄膜厚度必须小于100 g/m 2. ，烤箱必须有强制通风。对于液体油墨系统，试样膜的厚度不太重要。

1.1 These test methods cover the determination of weight content of nonvolatile matter in two types of printing inks. 1.2 Test Method A is applicable to heatset-type printing inks and resin solutions; solvents in such systems typically have initial boiling points in the range from 240 to 275°C (470 to 535°F) and vapor pressures less than 0.2 mm Hg. 1.3 Test Method B is applicable to liquid-type printing inks and vehicles based on aqueous or organic solvents that evaporate readily at ordinary room temperatures. Note 1: Test Method A (for heatset systems) specifies a specimen film thickness that is much thinner than those produced by related test methods; one exception is Test Method B in Test Methods D1259 , which is recommended as a referee test. Note 2: Test Method B (for liquid ink systems) is similar to Test Method D2369 except that a solvent is not required for spreading the test specimen. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. 1.6 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. ====== Significance And Use ====== 4.1 Nonvolatile content of printing inks is useful for specification acceptance between the producer and the user. 4.2 In order to obtain accurate results for heatset systems within the specified 3-h heating time, the specimen film thickness must be less than 100 g/m 2 , and the oven must have forced ventilation. Thickness of the specimen film is less critical for liquid ink systems.
