1.1 这些试验方法涵盖了通过暴露于紫外线或加速电子束而固化的涂料、油墨和粘合剂的重量百分比挥发性含量的测定程序。 1.2 试验方法A适用于基本上为100的辐射固化材料 % 反应性，但可能包含痕迹（不超过3 %) 挥发性物质的杂质或通过加入各种添加剂引入。 1.3 试验方法B适用于所有辐射固化材料，但必须用于含有旨在控制应用粘度的挥发性溶剂的材料，并打算在固化前从材料中去除。 1.4 这些试验方法可能不适用于挥发性材料为水的辐射固化材料，经生产商和用户双方同意，可替代其他程序。 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 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。 具体危险说明见 15.7 . 1.7 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====== 5.1 这些试验方法是用于确定拟通过暴露于紫外线或电子束照射而固化的材料的挥发性成分的选择程序。 这些类型的材料包含液体反应物，在固化过程中反应成为薄膜的一部分，但在试验方法的试验条件下 D2369 ，将被错误地测量为挥发物。这些试验方法的条件与试验方法相似 D2369 包括在重量损失测定之前固化材料的步骤。挥发性成分被确定为处理挥发物和潜在挥发物的两个独立成分。处理挥发物是衡量实际固化过程中挥发物损失的一种方法。 潜在挥发物是对老化过程中或极端储存条件下可能发生的挥发物损失的测量。这些挥发性成分测量对于材料的生产商和用户以及确定排放量的环境利益都很有用。

1.1 These test methods cover procedures for the determination of weight percent volatile content of coatings, inks, and adhesives designed to be cured by exposure to ultraviolet light or to a beam of accelerated electrons. 1.2 Test Method A is applicable to radiation curable materials that are essentially 100 % reactive but may contain traces (no more than 3 %) of volatile materials as impurities or introduced by the inclusion of various additives. 1.3 Test Method B is applicable to all radiation curable materials but must be used for materials that contain volatile solvents intentionally introduced to control application viscosity and which are intended to be removed from the material prior to cure. 1.4 These test methods may not be applicable to radiation curable materials wherein the volatile material is water, and other procedures may be substituted by mutual consent of the producer and user. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in 15.7 . 1.7 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 ====== 5.1 These test methods are the procedures of choice for determining volatile content of materials designed to be cured by exposure to ultraviolet light or electron beam irradiation. These types of materials contain liquid reactants that react to become part of the film during cure, but, which under the test conditions of Test Method D2369 , will be erroneously measured as volatiles. The conditions of these test methods are similar to Test Method D2369 with the inclusion of a step to cure the material prior to weight loss determination. Volatile content is determined as two separate components—processing volatiles and potential volatiles. Processing volatiles is a measure of volatile loss during the actual cure process. Potential volatiles is a measure of volatile loss that might occur during aging or under extreme storage conditions. These volatile content measurements are useful to the producer and user of a material and to environmental interests for determining emissions.
