标准摘要
[中文适用范围]： 本文件规定了测定各种纸和纸板，特别是涂层或填充产品中二氧化钛含量的方法。 它包括两个最终测定钛的程序，其中一个依靠分光光度法，另一个依靠火焰原子吸收分光光度法。 测定的限度取决于取样量（8.1）。 注：该方法是为二氧化钛的测定而设计的。 以其他形式存在的钛，例如作为粘土的成分，不会干扰测定。 [外文原描述]： This document specifies a method for determining titanium dioxide content in all kinds of paper and board, in particular coated or filled products. It comprises two procedures for the final determination of titanium, one of them relying on spectrophotometry and the other on flame atomic absorption spectrophotometry. The limits of the determination depend on the amount of sample taken (8.1). NOTE The method is designed for the determination of titanium dioxide. Titanium present in other forms, for example as a constituent of clay, will not interfere in the determination.
