标准范围

ISO 1407:2009规定了三种定量测定可从天然橡胶和合成橡胶及其未硫化和硫化化合物中提取的材料的方法。方法A测量溶剂蒸发后溶剂提取物相对于原始测试部分质量的质量；方法B测量提取前后测试部分的质量差；仅用于生胶的方法C测量使用沸腾溶剂萃取前后测试部分的质量差。附件中给出了最适合每种橡胶的溶剂的建议。

ISO 1407:2009 specifies three methods for the quantitative determination of the material extractable from raw rubbers, both natural and synthetic, and their unvulcanized and vulcanized compounds.

• method A measures the mass of the solvent extract, after evaporation of the solvent, relative to the mass of the original test portion;
• method B measures the difference in the mass of the test portion before and after extraction;
• method C, which is for raw rubber only, measures the difference in the mass of the test portion before and after extraction using boiling solvent.

Recommendations as to the solvent most appropriate to each type of rubber are given in an annex.
