标准摘要
[中文适用范围]： 本国际标准定义了在橡胶工业中用作配合剂的硬脂酸（包括硬脂酸和棕榈酸的混合物），并规定了描述其性能的测试方法。 附录 L 中给出了硬脂酸和硬脂酸/棕榈酸混合物根据碘值的分类以及用于橡胶工业的此类材料的典型化学和物理性质。 附录 L 仅供参考。 在本国际标准中，原子吸收光谱法是优选的方法。 [外文原描述]： ISO 8312:2015 defines stearic acid (including blends of stearic and palmitic acid) for use as a compounding ingredient in the rubber industry and specifies the test methods for describing its properties. Classification of stearic acid and stearic acid/palmitic acid blends according to iodine value and typical chemical and physical properties for such materials for use in the rubber industry are given in Annex L. Annex L is given for information only. In this International Standard, the atomic absorption spectrometric method is the preferred method.
