1.1 本试验方法包括测定总酸接受度，包括卤化有机溶剂中的胺和中性型（α-环氧化物）稳定剂。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 第节中给出了具体的预防说明 7. 。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 稳定剂含量已耗尽的溶剂可能变为酸性。酸会对用于卤化溶剂的加工和储存设备造成腐蚀。 4.2 卤代有机溶剂可以含有胺型（碱性、水性可萃取）接受酸的添加剂、中性型（通常为环氧化物）接受酸添加剂或两者。该试验方法可以确定两种稳定剂的复合酸接受度。此外，如果胺酸验收是通过单独的程序确定的（见试验方法 D2106 )，溶剂中中性酸接受稳定剂的量可以根据组合酸接受值和胺酸接受值之间的差来计算。 4.3 生产商和用户可以使用该测试方法来验证产品是否符合酸接受产品规范，或者用户可以使用此方法来监测使用中溶剂的酸接受能力。

1.1 This test method covers the determination of the total acid acceptance including amine and neutral type (alpha epoxide) stabilizers in halogenated organic solvents. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. Specific precautionary statements are given in Section 7 . 1.4 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 Solvents that have been depleted in stabilizer content can become acidic. Acids can cause corrosion to process and storage equipment used for halogenated solvents. 4.2 Halogenated organic solvents may contain amine type (alkaline, aqueous extractable) acid accepting additives, neutral type (typically epoxide) acid accepting additives or both. This test method can determine the combined acid acceptance from both types of stabilizers. In addition, if the amine acid acceptance is determined by a separate procedure (see Test Methods D2106 ), the amount of neutral acid accepting stabilizers in a solvent can be calculated from the difference between combined and amine acid acceptance values. 4.3 This test method may be used by producers and users to verify that a product is complying with acid acceptance product specifications or by users to monitor the acid accepting ability of a solvent in use.
