1.1这些试验方法（如适用）包括由于卤化有机溶剂中存在可通过标准酸滴定的有机胺而测定其酸接受度。这些试验方法适用于重量百分比为0.001至0.02（10%）的样品 – 200 ppm）碱度，如NaOH。包括以下两种测试方法: 1.1.1 试验方法A — pH法，以及 1.1.2 试验方法B — 指示剂法。 1.1.3 试验方法C — GC方法。 1.2 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法有助于测定胺或碱与其他受酸化合物相比的受酸量。

1.1 These test methods, where applicable, cover the determination of the acid acceptance of halogenated organic solvents due to the presence therein of an organic amine titratable by standard acid. These test methods are suitable for samples of 0.001 to 0.02 weight percent (10 – 200 ppm) alkalinity as NaOH. Two test methods are covered as follows: 1.1.1 Test Method A — pH Method, and 1.1.2 Test Method B — Indicator Method. 1.1.3 Test Method C — GC Method. 1.2 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method is useful for the determination of the amount of acid acceptance contributed by amines or bases as compared to other acid-accepting compounds.
