Foreword
SN/T 0065 "Importers rich europium, yttrium-rich, samarium, europium, gadolinium oxide measurement method" standard series is divided into three parts:
--- Part 1: Determination of moisture
--- Part 2: Determination of loss on ignition
--- Part 3: Determination of total rare earth oxides
This section SN/T Section 20065 of.
This Part replaces SN 0065.2-1992 "export rich europium, yttrium-rich, samarium, europium, gadolinium oxide --- Gravimetric Determination of ignition loss."
": Chemical analysis methods - Part 4 standard writing rules" provisions of this section in accordance with SN 0065.2-1992 GB/T 20001.4
Be revised.
This section compared with SN 0065.2-1992 main changes are as follows:
--- Add a description of the preamble;
--- Delete the obsolete GB 4471 "between Chemical test method precision laboratory tests to determine the repeatability and reproducibility";
--- Given precision repeatability limit, the reproducibility of the method has been covered limit measurement range, delete the original standard "critical difference between the 6.2 meter
Operators "clause.
