标准摘要
[中文适用范围]： 本文件规定了橡胶和橡胶制品中生物基质量含量的测定方法。 橡胶材料或最终产品的生物基质量含量可通过将样品分离为橡胶、无机成分（包括炭黑）和溶剂提取物，分别测定 14C 含量，然后将结果转换为生物基质量含量来确定。 使用本文档中描述的程序批量内容。 本文件适用于 NR、IR、BR、SBR、IIR、BIIR、CIIR 及其改性橡胶及其混合物。 本文件仅使用加速器质谱（AMS）方法来测定生物基含量。 [外文原描述]： ISO 19984-3:2017 specifies measuring methods for the determination of the biobased mass contents in rubber and rubber products. The biobased mass content of rubber materials or final products can be determined by separating the sample into the rubber, the inorganic ingredient (including carbon black) and the solvent extract, each of whose 14 C content is determined, and then converting the results to the biobased mass content using the procedure described in this document. ISO 19984-3:2017 applies to NR, IR, BR, SBR, IIR, BIIR, CIIR and their modified rubbers, as well as to their mixtures. ISO 19984-3:2017 uses only the accelerator mass spectrometry (AMS) method for the purpose of determination of biobased content.
