ISO 19984-3:20 17规定了测定橡胶和橡胶制品中生物基质量含量的测量方法。 橡胶材料或最终产品的生物基质量含量可以通过将样品分离成橡胶、无机成分(包括炭黑)和溶剂提取物来确定，其各自的14C含量被确定，然后使用本文所述的程序将结果转换成生物基质量含量。 ISO 19984-3:20 17适用于NR、IR、BR、SBR、IIR、BIIR、CIIR及其改性橡胶，以及它们的混合物。 ISO 19984-3:20 17仅使用加速器质谱（AMS）方法测定生物基含量。

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 ¹⁴C 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.
