1.1 本试验方法涵盖AMS（α-亚甲基苯乙烯）聚合物含量的测定。二聚体和三聚体不通过这些测试方法测量。 1.2 该试验方法适用于测定浓度高达15 mg/kg的AMS的聚合物含量。测量前，必须适当稀释聚合物含量超过15 mg/kg的样品。 1.3 在使用该方法确定测试结果是否符合适用规范时，应根据修约方法对结果进行修约 E29年 . 1.4 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。 1.5 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和健康实践，并确定监管限制的适用性。 有关具体的危险说明，请参阅第节 8. . ====意义和用途====== 4.1 该试验方法可用于测定AMS单体中的聚合物浓度。 4.2 本试验方法不会检测二聚体和三聚体。 4.3 该测试方法可用于工厂控制和规格分析。

1.1 This test method covers the determination of the polymer content of AMS (α-Methystyrene). Dimers and trimers are not measured by these test methods. 1.2 This test method has been found applicable to determining the polymer content of AMS in concentrations up to 15 mg/kg. Samples containing more than 15 mg/kg of polymer must be suitably diluted before measurement. 1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29 . 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8 . ====== Significance And Use ====== 4.1 This test method can be used for determining polymer concentrations in AMS monomer. 4.2 This test method will not detect dimers and trimers. 4.3 This test method can be used for plant control and for specification analysis.
