YS/T 575.1-2026Chemical analysis methods of bauxite ores - Part 1: Determination of aluminium oxide content - EDTA titration method (English PDF)

YS/T 575.1-2026 is the English-translated version of 铝土矿石化学分析方法 第1 部分：氧化铝含量的测定EDTA 滴定法.

Part 1 of the series on chemical analysis of bauxite ores describes the determination of aluminium oxide content by EDTA titration. It applies to the determination of aluminium oxide in bauxite ores over a measuring range of 30.00% to 80.00%.

It is used by bauxite mines and traders, by alumina refineries that buy the ore, and by analytical and inspection laboratories. It is a voluntary standard, as the /T in the code shows. It was approved by the Ministry of Industry and Information Technology, issued on 15 April 2026 and takes effect on 1 November 2026. It replaces YS/T 575.1-2007.
