标准摘要
[中文适用范围]： 吸油值（OAN）是炭黑吸收液体能力的量度。 该特性是炭黑结构的函数。 邻苯二甲酸二丁酯 (DBP) 或石蜡油均可与标准粒料等级一起使用，包括 ASTM D1765 中发现的 N 系列炭黑，尽管使用石蜡油对某些特种炭黑和粉炭黑进行 OAN 测试可能会导致与使用 DBP 油进行 OAN 测试。 虽然研究表明这两种油具有相当的精度，但石蜡油具有无害的优点。 本标准规定了使用吸光度计测定橡胶工业用炭黑吸油值的方法。 用同样的方法测定炭黑压缩样品的吸油值。 附录 A 中描述了压缩样品的制备程序。 [外文原描述]： Oil absorption number (OAN) is a measure of the ability of a carbon black to absorb liquids. This property is a function of the structure of the carbon black. Either dibutyl phthalate (DBP) or paraffin oil is acceptable for use with standard pelleted grades, including N‑series carbon blacks found in ASTM D1765, although OAN testing using paraffin oil on some speciality blacks and powder blacks might result in unacceptable differences as compared to OAN testing using DBP oil. While studies have shown the two oils to give comparable precision, paraffin oil offers the advantage of being non-hazardous. ISO 4656:2012 specifies a method using an absorptometer for the determination of the oil absorption number of carbon black for use in the rubber industry. The same method is used for the determination of the oil absorption number of compressed samples of carbon black. The procedure for the preparation of the compressed samples is described in an annex.
