ISO 19984-2:20 17规定了测定橡胶和橡胶制品（包括聚氨酯）中生物基碳含量的测量方法。这些方法侧重于橡胶或橡胶产品中的碳原子，并通过放射性碳同位素14C的浓度来确定含碳成分是否是生物基的。 ISO 19984-2:20 17适用于橡胶和橡胶制品，如原材料、材料和最终产品。

ISO 19984-2:2017 specifies measuring methods for the determination of biobased carbon contents in rubber and rubber products, including polyurethanes. The methods focus on carbon atoms in rubber or rubber products, and determine whether the carbon-containing component is biobased or not judging from the concentration of ¹⁴C, radiocarbon isotope. ISO 19984-2:2017 applies to rubber and rubber products such as raw materials, materials and final products.
