标准摘要
[中文适用范围]： 本国际标准规定了一种通过红外反射率测量测定有效残留墨水浓度（ERIC 数）的方法。本国际标准适用于所有类型的脱墨再生纸浆以及由再生纸浆制成的机制纸页，其中残留墨水为黑色。该方法仅适用于在 950 nm 处的不透明度小于 97% 的片状材料。所得的 ERIC 数取决于墨水颗粒的分布，该方法对亚微米颗粒最有效。只有当测试材料在墨水分布、成形和定量方面均匀，以至于将纸页的不同部分呈现给反射率计的测量孔径时产生非常相似的读数，所得值才可靠。 [外文原描述]： ISO 22754:2008 specifies a method for the determination of the effective residual ink concentration (ERIC number) by infrared reflectance measurement. ISO 22754:2008 is applicable to all types of deinked, recycled pulp and to sheets of machine-made paper made from recycled pulp, where the residual ink is black. The method is applicable to materials available in sheet form only if the opacity at 950 nm is less than 97 %. The ERIC number obtained is dependent on the distribution of ink particle sizes, and the method is most effective for submicron particles. The value obtained is reliable only if the test material is uniform in ink distribution, formation, and grammage such that presenting different parts of the sheet to the measuring aperture of the reflectometer produces very similar readings.
