Foreword
This standard is GB/T 2288-1980 "Determination of Water coking products", GB/T 5074-1985 "coking products moisture content
Microcoulometry Determination ", GB/T 6711-1986" Determination "Huang blood sodium salt water on the basis of three criteria, the distillation, constant weight method
And determination of Karl Fischer method of moisture combined three coking products as a standard for high-temperature coal tar processed resulting product moisture
Determination.
This standard replaces GB/T 2288-1980, GB/T 5074-1985, GB/T 6711-1986.
This standard and GB/T 2288-1980, GB/T 5074-1985, GB/T 6711-1986 compared to the main changes are as follows.
--- Increasing the foreword, normative references, etc;
--- Revised the scope of content;
--- Increased principle, take the sample requirements, the revised test procedure;
--- Revised measurement method, the test procedure for the revision of law capacity, and increases the Karl Fischer reagent water titer repeatability.
