标准摘要
[中文适用范围]： ISO 13099 的这一部分描述了在非均相系统（例如分散体、乳液、具有液体分散介质的多孔体）中电和声学 zeta 电位测定方法。对zeta电位值和分散相的质量分数没有限制；包括稀释系统和浓缩系统。颗粒尺寸和孔径被认为在微米级或更小，不受颗粒形状或孔隙几何形状的限制。平面上zeta电位的表征将单独讨论。分散介质的液体可以是水性的或非水性的，具有任何液体电导率、介电常数或化学组成。粒子的材料可以是导电的，也可以是不导电的。双层可以是隔离的，也可以是重叠的，具有任意厚度或其他属性。 ISO 13099 的这一部分仅限于对电场强度现象的线性效应。假设表面电荷沿界面均匀分布。与含有空间分布表面电荷的软表面层相关的影响超出了范围。 [外文原描述]： This part of ISO 13099 describes methods of zeta-potential determination, both electric and acoustic, in heterogeneous systems, such as dispersions, emulsions, porous bodies with liquid dispersion medium. There is no restriction on the value of zeta-potential or the mass fraction of the dispersed phase; both diluted and concentrated systems are included. Particle size and pore size is assumed to be on the micrometre scale or smaller, without restriction on particle shape or pore geometry. The characterization of zeta-potential on flat surfaces is discussed separately. The liquid of the dispersion medium can be either aqueous or non-aqueous with any liquid conductivity, electric permittivity or chemical composition. The material of particles can be electrically conducting or non-conducting. Double layers can be either isolated or overlapped with any thickness or other properties. This part of ISO 13099 is restricted to linear effects on electric field strength phenomena. Surface charge is assumed to be homogeneously spread along the interfaces. Effects associated with the soft surface layers containing space distributed surface charge are beyond the scope.
