Scope
GB/T 23834.1-2009 is the English-translated version of 硫酸亚锡化学分析方法 第1部分：硫酸亚锡含量的测定 重铬酸钾滴定法.
GB/T 23834.1-2009 sets out the potassium dichromate volumetric method for determining the main content of stannous sulfate.
Clause 1 states that this Part covers the method summary, safety tips, general provisions, analysis steps and calculation of results for that titration, that it applies to the determination of the main content of stannous sulfate, and that the determination range of the method is w(SnSO4) greater than 95%.
Its contents list names Scope, Normative references, Method summary, Safety tips, General provisions, Reagents, Analytical procedures and Calculation of results.
The normative references are GB/T 601 and GB/T 603 on the preparation of standard volumetric solutions and of reagent solutions for test methods, GB/T 6682-2008 on water for analytical laboratory use, and HG/T 3696.1 and HG/T 3696.3 on the preparation of volumetric and reagent solutions for the chemical analysis of inorganic chemical products.
The document is Part 1 of GB/T 23834 Chemical analysis method for stannous sulfate, a series of six parts whose other parts determine insoluble substance in hydrochloric acid, alkali metal and alkaline-earth metal sulfates, lead and copper, arsenic, and iron.
It was proposed by the China Petroleum and Chemical Industry Association and falls under the jurisdiction of the Inorganic Chemical Industry Branch of the National Chemical Standardization Technical Committee (SAC/TC 63/SC 1), and the foreword records it as a first release. It was issued on 18 May 2009 and has applied since 1 February 2010.
